Plants make molecules that chemists could never imagine. Chemical poisons that deter herbivores are advantageous for organisms that can’t move.  For humans, depending on the dosage, these molecules can be either poisonous or medicinal. The small shrub circled here is Pacific Yew.  In 1962 it was discovered that its tissues, especially the bark, contain ‘taxol’ effective in treating cancer.  It took many kg of bark (in 1993 34,000 kg were harvested in BC) for a single dose – and killing the tree. Now the drug is synthesized in a lab using precursors from the needles.  The seed is surrounded by red, fleshy tissue called an ‘aril’, sometimes incorrectly called a ‘berry’.

    In an earlier post I mentioned that Luke Halpin was out surveying marine mammals and birds from the deck of the CCGS John P. Tully, and spotted something totally different west of Brooks Peninsula. The fish was estimated at 3.5-4 meters in length, and was cruising against the current just below the surface.

    But until the paper announcing his find was accepted by a scientific journal, I didn’t want to spill the beans and say what he had found. His research paper (Halpin et al. 2018) will be published in the spring issue of the Northwestern Naturalist.

    This picture says it all – there is no debating what this fish is – only one species that fits the bill. Swordfish are known north to the southern Kuril Islands in the western Pacific, but Luke’s find is the northern-most record for the species in the eastern Pacific and is conclusive evidence of this species right along our coast.

    A Google Earth image showing where the Swordfishes from 2017 and 1983 were found relative to Vancouver Island.

    A previous record from 1983 (see Sloan 1984, and Peden and Jamieson 1988) was from just inside of our exclusive economic zone (EEZ) and barely qualified as a BC fish. The 1983 specimen was caught as by-catch at 47°36’N, 131°03’W, during an experimental fishery survey by the M/V Tomi Maru. The rostrum and tail were preserved in the Royal BC Museum’s fish collection (RBCM 983-1730-001). I am guessing the edible bits in between were cut into steaks, and ended up on someone’s dinner table. At least Luke’s Swordfish was left alone and for all we know, is happily cruising south to slightly warmer water.

    Keep your eyes peeled for deep-sea fishes while strolling along our shores. In the last month, three King-of-the-Salmon (Trachipterus altivelis) have washed up in the Salish Sea. Two were found in September (21st and 26th) in the Oak Bay area, Victoria. One of these was still swimming when found. A third was found October 3rd in Hood Canal, in Puget Sound. The first Oak Bay specimen will be preserved for the Shaw Centre for the Salish Sea in Sidney, the second was not recovered, and the third will be preserved in the Burke Museum’s collection. The Royal BC museum has 18 Trachipterus specimens, with several of these from the Salish Sea area.

    The King-of-the-Salmon from Hood Channel, photographed by Randi Jones.

    Is this species new to the region? No. The species ranges from Alaska to Chile, and knowledge of this species pre-dates European arrival on this coast. Is this trio of King-of-the-Salmon a case of post-spawn mortality? A sign of change in our oceans? We don’t know. Actually, when you look at the diversity of marine fishes off our coast, there is a lot of basic biology that we don’t know. We also get Longnose Lancetfishes (Alepisaurus ferox) washing up from time to time, although it has been a few years since I have heard report of a Lancetfish in the Victoria region.

    King-of-the-Salmon swim by passing a sine wave down their dorsal fin – they can get a fair bit of speed just by doing that. They can also reverse using the same fin flutter. They slowly turn by putting a curve in the body. However, in the first few seconds of the linked video you can see that they also swim in a more typical fishy way (using eel-like body oscillation) when they need a burst of speed or a really quick turn. If you’d like to see this form of locomotion in person – you can see it in a pet shop. Knife fishes use the same basic locomotion method – except they use their anal fin rather than the dorsal.


    Close up of the head of the King-of-the-Salmon showing the premaxillary (red) and maxillary (green) bones extended, photographed by Randi Jones.

    Note also in the video that the fish has a very short face compared to the Hood Channel specimen photographed onshore. As with many fishes, the jaws of the King-of-the-Salmon are protrusible – the premaxillary and maxillary bones swing out to create a tube – the gill chamber dilates, and water rushes into the mouth along with the prey. The same sort of suction pump mechanism is used by a wide variety of fishes – from tiny seahorses to giant groupers. Once the prey item is inside the fish’s mouth, the mouth closes, water is released through the gills and the prey is swallowed. The entire sequence is lightning fast – even in pipefishes and seahorses – blink and you miss it. In some fishes, the process is even audible – you can hear a snapping sound when seahorses slurp up crustaceans (and fishes). You can’t hear the same snapping sound when larger fishes engulf their prey, but it is no less dramatic an effect.

    In 2014, a Louvar and a Finescale Triggerfish were found in BC – a double-header of interesting southern fishes in our waters. But wait…  it looks like 2017 is also a double-header for cool coastal fish.

    This summer of 2017 (and in 2016), Basking Sharks were sighted here in BC. I think every Basking Shark is newsworthy given that they were nearly eliminated here in an ill-conceived plot to protect BC fisheries (see Wallace and Gisborne 2006 for that sad story). This year’s Basking Sharks were found in Caamano Sound in July, and near the Delwood Seamounts in August. Was it one roving shark? Or two? Are there others?

    This September however, Luke Halpin was out surveying marine birds from the deck of the CCGS John P. Tully, and spotted something totally different west of Brooks Peninsula. The fish is estimated at 3.5-4 meters in length, and was cruising against the current just below the surface.

    We are really fortunate that it was sunny and seas were so calm – because his picture leaves no doubt as to the fish’s identification. The best part about the story is that the fish is still out there. Don’t get me wrong, I’d have loved to have the fish as a specimen for the museum’s collection – but then again, it would require a custom vat – three to four meter fishes don’t fit in jars.

    This species is known north to the southern Kuril Islands in the western Pacific, but Luke’s find is the northern-most record for the species in the eastern Pacific and is conclusive evidence of this species as a new addition to our coastal fish fauna. Which species did he find? You’ll have to wait until he publishes his observations in a scientific research paper. Consider this a trailer – a teaser – there’s a big fish out there – it is cool… and I am jealous. I would love to see this fish alive.

    The Doncaster population of the European Wall Lizard probably is 6 years old based on conversations I have had with home owners. In the Google Earth image – the white dots are known locations – the green dots are new locations for 2017.

    How do I know these are new? Homeowners specifically said they had no lizards in 2016 – but they certainly do now. That’s the power of local knowledge and citizen science. The green dots along Oak Crest Drive were newly reported in the spring of 2017, with at least three adult lizards now known on the property. The two green dots along Cedar Avenue to the northeast are based on sightings of at least three young lizards – probably lizards that hatched this year and got well-clear of their parent’s territory. Cannibalism is a good emigration motivation.

    Based on where lizards were known in 2016, these 2017 records represent range extensions from 20 to 100 meters. Compared to their body size, that’s pretty decent dispersal given that adult lizards only grow to 21 cm (those fortunate enough to have a perfect tail), and in many cases, the dispersing lizards are young-of-the-year at 8 or so centimeters in total length.

    If younglings continue to bolt at this rate and make a bee-line south, I will have lizards in my garden in 2 years. More realistically, it will be another 3 years before we see them along our raised beds or in our greenhouse – not that I’m counting.

    We now have 21 orca specimens at the Royal BC Museum—the latest to arrive was T-171, a 6.07 meter female Biggs Orca which was found near Prince Rupert, October 19th, 2013. She had pinniped skulls, vibrissae (whiskers) and partially digested bones in her gut but was emaciated. Why was she emaciated?

    During the necropsy, researchers discovered that T-171 had mid-cervical to lumbar vertebrae with severe overgrowth of the neural arches and lateral processes (noted as spondylosis in the necropsy) – the overgrowth looks roughly like popcorn or cauliflower – and had the effect of interlocking some vertebrae. This likely explains her emaciated state. Was she able to hunt? Was she supported by her relatives?

    The skull of T-171 (ventral (palatal) view [left], right side [center], and dorsal view [right]) awaiting its catalog number and final place in the Royal BC Museum collection.

    Comparison of T-171’s vertebra (left) with overgrowth of bone vs. the normal vertebra of another Biggs Orca (12844) (right). The two vertebrae are not from the exact same position along the spine, but the difference between the two is still shocking.

    Many of T-171’s vertebral centra are eroded and porous – not like those of a healthy animal (12844).

    The overgrowth of the neural arches pinched the spinal chord of T-171; compare to a neural arch of 12844 (right). The vertebral malformation must have limited this animal’s mobility. It is hard not to anthropomorphize and imagine the discomfort due to this deformation.

    T-171 originally was prepared for exhibit at the Royal Ontario Museum, but they wanted a clean articulated skeleton for exhibit. In contrast, we were interested in T-171 because of its skeletal malformation. To make a short story long, we came to an agreement with the ROM to transfer T-171 to the Royal BC Museum, and since, the ROM has acquired L95 (Nigel), a 20 year old southern resident who was found near Esperanza Inlet, March 30th, 2016.

    Which Orca is next? In most cases we have no clue – it is not like we hunt orca just to add them to the collection. And we don’t usually have a production line of specimens in preparation. New specimens are acquired when a body washes up, and we make a snap-decision to cover the cost of specimen recovery and preparation. However, September 15, 2016, T-12A (Nitinat) was found off Cape Beale and towed to Banfield. I was contacted September 16th to see if the Royal BC Museum was interested (obviously that was a YES), and now his massive skull is being prepared. Once degreased, Nitinat’s skull will be added to the Royal BC Museum collection – sometime in 2018 – and made available for scientific research.

    As a kid I collected many things – from reptiles and amphibians to model airplanes to Star Wars cards – and now look where I am. I dress in black and white as a Stormtrooper with the 501st legion and collect black and white delphinids – Killer Whales – for the Royal BC Museum. Life sure takes you to unexpected destinations.

    A little while back I was musing over a spot on my Wall Lizard map that shows a large expanse east of Highway 17 between Cordova Bay Road to Mt Newton Cross Road that appears to be Wall-Lizard-free turf. Wall Lizards are crawling everywhere just the other side of the highway on Tanner Ridge. Either no one has reported lizards from this area – and it seems unlikely given how many reports I receive each year, or lizards have not been able to cross HWY 17.

    Cedar Hill Road in the Southeast Cedar Hill area also seems to be a decent barrier even though it is not a particularly busy road. Lizards have been in that area for about 6 years(as of 2016) and have crossed Derby Road without a problem – but not Cedar Hill Road. Cedar Hill may be just busy enough to limit the survival of adventurous lizards.

    It seems interesting that a lizard as fast as the Wall Lizard could not cross – but then again – why would they? Young ones disperse to avoid cannibalism, but perhaps the noise, vibration and sight of passing vehicles is enough to dissuade all but the most suicidal of lizards.

    I recently tripped across an article detailing road crossing behaviour in snakes (Andrews and Gibbons 2005). In their study, smaller snakes seemed to avoid crossing roads, whereas larger snakes have no problem with the concept. I wonder if the same is true for Wall Lizards? Interestingly, all snake species they studied crossed perpendicular to the road’s length – an adaptive behaviour minimizing distance and time on the tarmac. Some species froze in place when a car passed – that is maladaptive – and significantly increased an animal’s exposure to vulcanized rubber.

    I have not seen Wall Lizards crossing a street – but would be interesting to see if they too cross perpendicular to the curb, and whether they blast across or dart and pause – unintentionally increasing their risk of catastrophic z-axis reduction.

    Another lizard arrived in BC last week. We can add Brown Anole (Anolis sagrei) to our list of accidental imports – but this certainly is not the first one to have arrived by accident in BC. Many lizards travel the globe as stow-aways. This one travelled here in its egg along with a Snake Plant (also known as the Mother-in-Law’s Tongue). Sansevieria are popular houseplants – Snake Plants are easy to keep and look neat. My wife bought one for our living room – no lizards in our plant though.

    Where was the plant from? Who knows. This plant could have come from anywhere. Brown Anole’s have invaded Florida, and southern parts of Georgia, Louisiana, Mississippi, and Alabama. They also have invaded Hawai’i, southern Texas and southern California along with their relative the Green Anole (Anolis carolinensis). The Green Anole is native to the south-eastern United States, and in their native range, Green Anoles may be forced out of their usual habitat by their exotic relatives. Brown Anoles are native to Cuba and the Bahamas.

    Even if it got loose, this anole would not survive our winter. It was no real threat to our environment or fauna, but does show that the transport of exotic species is ridiculously easy – an egg in the soil in a plant pot. This time we are fortunate. Only one egg was present. Anoles are light-weight arboreal lizards which lay one egg at a time, and they are not parthenogenetic. Anole eggs develop in alternate ovaries at about a two week interval – if I remember correctly. This ensures the female lizard is not excessively encumbered, and for us it meant that only one egg likely was present in the pot (or any other pot at the home hardware store).

    Brown Anole eggs are a bit bigger than a Tic-Tac candy, so no wonder they are overlooked – they also are buried a centimeter or so in the soil – so they’d be out of sight. As long as the soil was not disturbed, was warm and moist – but not too wet, and the egg was not rolled, the developing embryo would survive transport.

    I wonder where this lizard’s brothers and sisters ended up? They could be anywhere. Since the lizard travelled here in an egg, I vote we name it Mork. Na-Nu Na-Nu.

    Just tripped across this fish while sorting out odd records in the RBCM fish database.

    999-00114-001 – unidentified fish – Family Triglidae (Searobins, Gurnards)

    Well, it turns out to be Prionotus stephanophrys – a Lumptail Searobin – and a new family, genus and species for BC.  Three other triglid species (two of them are Prionotus species) are known to stray into Atlantic Canada.

    This one was caught in 1998 on La Perouse Bank, it was added to the RBCM collection in 1999, and sat there ever since. No one had taken a second look at this specimen – until today. It was completely new to our system and as such, I had to add the genus and species to our database’s taxonomic tree.

    Until now, its northern record was off the mouth of the Columbia River – this new(ly rediscovered) record extends this family north about 260 km in the eastern North Pacific Ocean.

    The lower three pectoral rays of this fish are almost like fingers – it probably walks along the bottom like other triglids – the walking mechanism makes me think of face-hugger Alien larvae.

    I took these photos of Royal BC Museum lizard specimens with my iPhone 4 through the eyepiece of the old dissecting microscope in my lab. Then sent the photos via two emails to office thanks to WiFi – and to think – this is the “low-tech” way of doing things these days. Low-tech – sending files through the air from a hand held device… I have to laugh how technology has changed since I was a kid with my first pet lizards. The nerd in me can’t help but hear James Earl Jones’ voice – “Several transmissions were beamed to your inbox. I want to know what happened to the scans they sent you.”

    In earlier blogs I have mentioned scale differences between BC lizards – so I thought I may as well take close-up shots to clearly show the differences. Under a dissecting microscope (diss-secting, not die-secting), you can easily see the shape of the bead-like back scales of the European Wall Lizard (Podarcis muralis). It’s like a microscopic cobblestone pavement. Each scale is about the diameter of a standard sewing pin.

    European Wall Lizard (2112)

    The larger back scales of the Northern Alligator Lizard (Elgaria coerulescens) are painfully obvious, and each scale has its own raised keel. The keel gives each scale an angular appearance.

    Northern Alligator Lizard (1358)


    The Pygmy Short-horned lizard (Phrynosoma douglasii) has a really complex squamation with tiny granular scales interspersed between clusters of larger keeled scales. The larger scales are raised into spires above the general scale-scape (the lizard equivalent of landscape).

    Pygmy Short-horned Lizard (323)


    Western Skinks (Plestiodon skiltonianus) by contrast are painfully even and smooth – yawn. It’s a good thing they have speed-stripes and a bright blue tail to make them stand out in a crowd.

    Western Skink (1964)


    Western Fence Lizards (Sceloporus occidentalis) have scales each with a trailing spine – characteristic of all Sceloporus species. Some, like the Crevice Spiny Lizard in the United States have really robust spines on their scales, others like the Sagebrush Lizard have tiny spines. Cordylids in Africa take spiny scales to a whole new level.

    Sorry, I forgot a scale bar in the photos, but the images were fairly close to the same magnification.

    Abstract: Phragmites australis (common reed) is a widespread perennial grass of wetland habitats, with cryptic native and introduced subspecies in North America. We determined the relative abundance of the subspecies and the distributions of plastid DNA haplotypes throughout British Columbia, Canada, at the northwestern distribution limit of common reed in North America. Of 203 specimens assigned to subspecies using molecular markers, we identified only 9 plants as the introduced ssp. australis; all remaining samples were the native ssp. americanus. The two subspecies co-occurred at only one locality. We identified four native haplotypes (one widespread in British Columbia and three others more localized) and two introduced haplotypes. Using plants of known haplotype, we assessed the utility of different morphological traits and trait combinations for distinguishing native and introduced subspecies in this geographic region. No single morphological trait was diagnostic, but principal components analysis and identification indices based on combinations of traits consistently separated the native and introduced subspecies in our sample. Two- or three-trait combinations of ligule length, lemma length and stem anthocyanic coloration gave the best separation. These indices could reduce the need for confirmation of the introduced subspecies using molecular tools, facilitating efforts to monitor and control this invasive plant.

    You’d think that sharks and rays would be pretty well known along our coast. Did you know that two Hammerhead Sharks have been found off Vancouver Island? Even a Tiger Shark has strayed north to Alaska. Did it swim along the BC coast, or did it take a more direct route from Hawai’i? We’ll never know. However, in 2016 a new shark was added to our fish fauna – the Pacific Angel Shark (Squatina californica) – based on a clear photograph by Mark Cantwell and his detailed description of the dive location.

    We have known since 1931 that Angel Sharks ranged north to Seattle, and there is a single record from Alaska. The specimen label for this 35 cm Alaskan female had been lost (Evermann and Goldsborough 1907) and we cannot pin down its collection location with certainty. Until now, we had no Angel Shark records for British Columbia – but it was only a matter of time.

    On the 30th of April, 2016, a single adult Angel Shark was sighted by a diver off Clover Point right here in Victoria. The shark’s gender cannot be determined from the photograph since claspers, if present, are not visible. The Angel Shark was found in about 12 meters of water, about 30 meters off the point. The diver estimated the shark’s length at about 1.1 to 1.2 meters in length. The specimen was not collected, but it would have made a fantastic museum specimen.

    King and Surry (2016) published the discovery of this shark in BC in a recent issue of the Canadian Field-Naturalist. While this now is not breaking news – in fact it is a year late – people may still want the primary reference to our latest elasmobranch.

    PDFs are available here [as a new paper, King and Surry (2016) is available by subscription to The Canadian Field-Naturalist or by contacting the primary author]:

    Belted Kingfishers (Megaceryle alcyon) usually take fishes – why else would they be called kingfishers. They sometimes take crustaceans and frogs, and I’d be shocked if they turn their beaks up at big juicy insects. However, mammal predation is quite a dietary shift. Apparently no one explained the meaning of “fisher” to a kingfisher in the southwestern Yukon.

    This female obviously read its species description. Looks like she caught a young goldfish. (From:

    A paper came out in a recent issue of the Canadian Field-Naturalist (see Jung 2016) detailing the capture of a Western Water Shrew (Sorex navigator) by a Belted Kingfisher. That would make a decent meal and a real energetic boost for the Kingfisher. Jung (2016) mentioned that Belted Kingfishers have been known to take Eastern Water Shrews (Sorex albibarbis), and he (Jung 2013) also reported on a kingfisher trying to subdue a Spotted Bat (Euderma maculatum).


    Imagine if kingfishers changed tactics to regularly prey on other small animals? Their ecology could converge on that of butcher birds (shrikes). What’s next? Lizards and snakes?(Yes, shrikes impale their prey on thorns (or barbed wire) to age a bit).

    Sure glad kingfishers aren’t the size of a Banshee or Leonopteryx from Avatar, or we’d all be at risk when swimming.

    Keep your eyes on the sky. And as for that specific Water Shrew, all you can say is: “Hair today, gone tomorrow.”

    Was this an odd title? Actually I think the song went,

    “On top of spaghetti…  all covered with cheese,

    I lost my poor meat ball…  When somebody sneezed.

    It rolled off the table…  and onto the floor.

    And then my poor meat ball…  rolled out of the door.

    Wow that was a dredged from deep cephalic crevices…

    Anyway, I got a tip from Purnima Govindarajulu, my herpetological counterpart in the Ministry of Environment that she’d seen a European Wall Lizard on Mount Tolmie here in southern Saanich. Given how fast and far Wall Lizards are spreading, it was only a matter of time before they colonized this rock. This pocket of lizards will form another expanding sub-population – pretty-much midway between the single lizard I saw at the University of Victoria and the lizards near Doncaster School.


    This morning (April 27th) was nice and sunny, and I hiked up to the summit after dropping my daughter at daycare. What did I find first? A Northern Alligator Lizard. That made me very happy – I don’t see those everyday and this lizard was more than patient with the iphone-wielding twit who wanted its picture.


    Then less than 2 meters away were the Wall Lizards – five of them. A meter or so along the road, another Wall Lizard. Up along the southeast corner of the reservoir – another large male Wall Lizard.

    Yep, looks like they have found a solid toe-hold in this region. Cedar Hill X Road may make a decent barrier to northward dispersal (not that Wall Lizards aren’t north of there anyway) – but they will easily spread southeast and southwest into gardens adjacent to the park. Note the small scales and green colour on this Wall Lizard’s back, compared with the larger coppery scales on the Alligator Lizard (above).


    Keep your eyes on rock gardens, rock walls, woody debris, and any bedrock with decent cracks for shelter. The photo below shows just how slender the Wall Lizards are – this one with an intact tail is the largest lizard I have caught to date (21.2 cm total length). After checking the RBCM’s herps database, I see that the only months where I haven’t caught Wall Lizards are January and February – too bad that this spring was consistently cold and wet. I have missed my chance to get a full year’s worth of lizards in 2017.

    Yesterday I worked with Chris O’Connor from our Learning Department – we took some children on a tidepool tour. The main point was to chat about museum collections and things we record or measure when we are out sampling. We didn’t go crazy catching fishes, only taking 3 Tidepool Sculpins (Oligocottus maculosus) in the end. But we talked about our role as museum researchers, and why we take more than 1 specimen (if possible) to get an account of variation within and between species.

    You can see slight differences between these fishes – even an injury – just like the subtle, or not so subtle differences we see in each other.

    The three fishes will be added to the Royal BC Museum’s ichthyology collection, but before that, they are fixed in 10% Formaldehyde. Researchers used to drop fishes directly into Formaldehyde – many fishes died horrible deaths. When I accidentally get Formaldehyde in a cut – it stings intensely – I couldn’t imagine being dunked directly into that chemical.

    Today we are more humane, and give fishes an overdose of anaesthetic before immersion in Formaldehyde. They are dead before they are fixed, and are preserved with a relaxed posture. The primary anaesthetic I use is 2-Phenoxy-Ethanol, but it is hard to get without ordering from a chemical supply company, and the chemical is a suspected carcinogen. I still have about 500 ml of the stuff – so I will use up what I have. Do I really want to buy more? Maybe not.

    Do we have safer options? Yes, Clove Oil is a good anaesthetic if mixed as an emulsion in a small volume of 99% Ethanol. But you have to carry a jug of 99% Ethanol everywhere you go – that may not go over well at a Police check-stop. The up-side to this chemical mix is that you smell spicy at the end of the day if you accidentally spill some on yourself.

    People have tried Alka-Seltzer tablets. They fizz and release CO2, which knocks-out fishes – but the process is slow and some fishes (those like catfish that gulp air to survive in low oxygen conditions) are resistant and survive way too long in a stressful condition.

    A few months ago I tried using Oragel (20% Benzocaine) on European Wall Lizards – colleagues had found it worked well on amphibians. They put Oragel along the spine of an amphibian and it soaks into the skin; I give lizards an oral dose. It renders bullfrogs and wall lizards unresponsive in 20 seconds to a minute.  Oragel seems to be a convenient anaesthetic for these invasive herpetiles.

    Yesterday, I told the tidepool group that we’d be performing an experiment – I tried Oragel for the first time on the 3 sculpins we caught. As I hoped – less than 20 seconds and the fishes were out cold. 2-Phenoxy-Ethanol takes about the same time on similar sized fishes.

    The beauty of Oragel is that it is readily available, and if you run out, you can stop by the nearest pharmacy. It also is safe – we use it on sore teeth or gums. Perfect – it works fast on specimens and is safe for the researcher.

    Perhaps someone needs to do a larger scientific study to see how effective over-the-counter Oragel is on larger fishes. Maybe this is an effective over-the-counter tool for preserving new museum specimens.

    A specimen with no data is not worth keeping. A specimen with vague data is not worth keeping either. The Royal BC Museum’s ichthyology collection contains a vertebral centrum with cartilaginous remnants of its respective haemal arch and neural arch from a shark that washed up November 5th, 1975 (only a few months after Jaws was released in cinemas). It was cataloged as 976-00052-001 in the fish collection (with a variant of the catalog number listed as a previous number ~ B.C.P.M. #97652). Our electronic database only had a collection date for this centrum (no location, no collector).

    Flip to our original paper catalog, and we find that there is indeed a collection location: Ahousaht Village, Flores Island – but this never got translated to our electronic database. The paper catalog states that the shark washed up on a beach – but there was no latitude and longitude provided for the record beyond 49°N, 125°W. If you plot the western-most limit of 125°W, it is nowhere near Flores Island – so the location is questionable. Ahousaht Village’s nearest beach is at about 49°16’N, 126°03’W.

    Worse yet, the vertebral centrum indicates that this was a big shark – we don’t have a lot of big sharks here…

    Great White Shark (Carcharodon carcharias) reaches 6 meters

    Pacific Sleeper Shark (Somniosus pacificus) reaches 5-6 meters

    Basking Shark (Cetorhinus maximus) reaches at least 9 meters

    The shark centrum in the Royal BC Museum collection is about 7.3 cm in diameter – it spans most of the palm of my hand. This must have come from a decent-sized shark. Was it a small Basking Shark? A large Great White? A large Sleeper Shark? It’s not ‘reptilian’ so we can rule out Cadborosaurus (whew). Hang on, Cadborosaurus’ so-called “type specimen” was a photograph of a digested basking shark – Hmmm…

    It is a shame no one bothered to take a skin sample – the scales may have been diagnostic. What about teeth? A sample of teeth – even one tooth – would have been enough to identify this fish. Sadly though, nothing remains other than this centrum and a bit of cartilage. It was fixed in formaldehyde and stored in isopropanol – so I think we can forget sending a chunk to Guelph for DNA barcoding. DNA barcoding wasn’t a thing back in 1975, so tissue samples were not preserved for future analysis.

    If no one in Ahousaht has a photo of this shark on the beach, or some teeth stashed away, all I have to say is , “Sorry Charlie, the Royal BC Museum wants specimens with good data.”

    This winter has been cold here in Victoria – relatively speaking. We have had lots of rain, several rounds of snow – and I even had to shovel my driveway and sidewalk. Actually I have had to shovel several times this winter. The rest of the country is not all that sympathetic to the wintery-woes of its Pacific Islanders.

    One odd feature of Victoria is that Anna’s Hummingbirds are present year-round – because people feed them. Without artificial feeding stations, they likely would migrate south in autumn with the Rufus Hummingbird and return each spring. It still strikes me as strange to see a hummingbird in winter – given that I moved here from Winnipeg.

    In my neighbour’s yard there is Holly bush that is a regular nesting site for our resident male Anna’s Hummingbird – the spot must be coveted because the prickly leaves are a great deterrent to would-be nest thieves.

    This nest from 2005 was near the junction of Government Street and Niagra Street in James Bay – also in a Holly bush.

    Our hummingbird – yes we are possessive even though we don’t feed hummingbirds in winter – is a regular visitor to our veggie garden and flowers in summer. It stayed this winter even though it was snowy and cold. Someone nearby must have a hummingbird feeder.

    Not all Anna’s Hummingbirds were so lucky this year. Today I received a nest containing two feathered nestlings which were snuggled together in their soft little lichen-cup nest. This is certainly an early nesting attempt – they are known to nest from February to August, but nesting this early in the spring is a big risk.

    The fate of the female is a mystery (males don’t raise their young). Did she hit a window? Run short of food and die? Did a free-range domestic cat get her? These two nestlings were in a sheltered spot alongside a house here in Victoria, but without a parent, they didn’t last long. Natural selection can be as cold as this winter.

    In 2006 I spent a month at sea on the CCGS W.E. Ricker, collecting hundreds of deep sea fishes during a Tanner Crab Survey. Most fishes were identified the traditional way using anatomical features, but we didn’t have an extensive library on board, so many ‘field’ identifications were wrong. Such is life on the high seas when you are rushed to process samples.

    Several snailfishes and of course the poorly known Flabby Whalefishes were only identified to genus. One snailfish with its distinctive pelvic girdle resembling a pair of bat’s wings – was simply labeled as “Batwing.” It was a few years later while sorting out some of the samples, that I tripped across a paper by David Stein (1978) describing our “Batwing” species in detail – Osteodiscus cascadiae. Keep in mind that the last comprehensive book on BC fishes – Pacific Fishes of Canada – was published in 1973… I was 6 years old. Pacific Fishes of Canada needs an update – it is woefully out of date.

    This week I have been cataloging the last of the fishes caught on the 2006 Tanner Crab Survey – Screech – I know what you are thinking. A decade has passed since these fishes were caught. I am not a slacker – well, some would argue that – but there are many reasons why I am only now sorting and cataloging the last of the Tanner Crab specimens. Forgive me if progress is slow.

    Many of the specimens we collected in 2006 had a small plug of tissue removed for DNA Barcoding. Three specimens (DNA barcode field tags from left to right, G5036, INV792, and 0738-Bo2), from Queen Charlotte Sound and west of the northern end of Vancouver Island were identified as Careproctus canus. If this is correct, they are the first for British Columbia.

    The same can be said for specimens (barcode field tags from left to right, R5826 and G5026), both from Queen Charlotte Sound which were identified as Careproctus attenuatus. If correct, they are the first of their kind for BC, and both species C. canus and C. attenuatus, are way-south of their known ranges in the Aleutian Islands. We also caught one other snailfish identified as Paraliparis melanorhabdus (15943) – if correct it is the first specimen for the RBCM, but not the first for BC.

    When I got down to the last few unidentified fishes to catalog in the RBCM database, I found that they had tags from the DNA Barcoding project. Obviously I looked up the molecular identification, but I have to wonder whether a genetic sequence was used to identify these new snailfishes, or whether the DNA barcoding team used our field identifications. We certainly do not carry an exhaustive library at sea, and we do our best to identify fishes with what we have at our finger-tips while the decks are heaving and rolling. Since I don’t trust my own eye regarding snailfishes – these noteworthy records need to be verified – and I think I’ll send them to a snailfish expert that I know just south of the border.

    However, two specimens of Gyrinomimus (lovingly known as Flabby Whalefish) were identified as G. grahami (barcode tags, left to right INV0718 and R5828), and both were from west of the northern end of Vancouver Island. They don’t look much better in person. We left these specimens identified to genus because we had no literature for Flabby Whalefishes on board. As a result, I know the species-level identification did not come from me – and had to be based on molecular information. YAY, Gyrinomimus grahami (15942, 15935) is new to BC.

    These interesting records alone justify the time taken to collect and send DNA samples to Guelph for the barcoding project. I may not be a gene-jockey, but if the identifications of these fishes are correct, we will rack up another three new species for BC, boost our knowledge of biodiversity, finally have two of our whalefish specimens o-fish-ally identified. Now to compare the newly identified whalefish specimens to the other 10 jar-loads of specimens to see if we have one or more species in our collection.

    Thanks all you DNA barcoders – particularly Dirk Steinke who was out with us in 2006 – couldn’t have done this without you.


    In Canada, there are no native catfish west of the continental divide and until recently, the list of extant exotic catfishes in British Columbia only included introduced Black Bullhead (Ameiurus melas) and Brown Bullhead (Ameiurus nebulosus). We report that a single Yellow Bullhead (Ameiurus natalis) was collected from Silvermere Lake in the Lower Fraser River drainage. This represents the first record of the Yellow Bullhead in western Canada, and its introduction likely was accidental with a shipment of Largemouth Bass (Micropterus salmoides) rather than dispersal from Washington. Warm, eutrophic, weedy habitat in the Fraser Delta provides ample habitat for Yellow Bullheads and other exotic fishes. A Blue-eyed Panaque (Panaque suttonorum), a loricariid catfish found in 1995 in Shawnigan Lake, Vancouver Island, probably represents a single, illegally released aquarium fish, as does a large Silver Pacu (Piaractus cf. P. brachypomus), which was found in Green Lake on Vancouver Island in 2004.

    Polymerolepis whitei Karatajūtė-Talimaa, 1968 was described based on isolated polyodontode scales recovered from the Ukraine, and originally was thought to be heterostracan (Agnatha). Additional scales with neck canals were described years later, and as a result, P. whitei was reclassified as a bradyodont holocephalan because it had scales similar to those of Listracanthus Newberry & Worthen, 1870. Until now, no articulated body fossils were known, and so the classification of this taxon has remained uncertain and based only on the original author’s opinion. New specimens of P. whitei from the Mackenzie Mountains, Northwest Territories, Canada, show articulated scale patches from the head, with the best specimen showing part of an anal fin, caudal peduncle, and caudal fin. This new material confirms that the original account of scale variation was accurate, but also that P. whitei possesses an anal fin spine, a feature that, until recently, was thought to be a synapomorphy of acanthodian fishes among Palaeozoic fishes. Several primitive chondrichthyans (Obtusacanthus Hanke & Wilson, 2004; Lupopsyroides Hanke & Wilson, 2004; Kathemacanthus Gagnier & Wilson, 1996; Seretolepis Karatajūtė-Talimaa, 1968; Doliodus Traquair, 1893; Antarctilamna Young, 1982, and also problematic taxa such as Gyracanthides Woodward, 1902, and now Polymerolepis Karatajūtė-Talimaa, 1968), are known from articulated remains and show a fin-spine complement like that of acanthodian fishes. They also have placoid scales or polyodontode scales that grew by areal rather than superpositional accretion. These taxa blur the distinction that exists in historic literature between acanthodians and early chondrichthyans.

    New anatomical details are described for the acanthodian Lupopsyrus pygmaeus Bernacsek & Dineley, 1977, based on newly prepared, nearly complete body fossils from the MOTH locality, Northwest Territories, Canada. New interpretations of previously known structures are provided, while the head, tail, and sensory lines of L. pygmaeus are described for the first time. The pectoral girdle of L. pygmaeus shows no evidence of pinnal and lorical plates as mentioned in the original species description. Instead, the dermal elements of the pectoral region appear to comprise a single pair of prepectoral spines which rest on transversely oriented procoracoids, and large, shallowly inserted, ornamented pectoral fin spines which contact both the procoracoids and scapulocoracoids. The scales of L. pygmaeus lack growth zones and mineralized basal tissue, and superficially resemble scales of thelodonts or monodontode placoid scales of early chondrichthyans, and not the typical scales of acanthodians. However, L. pygmaeus possesses perichondrally-ossified pork-chop shaped scapulocoracoids, a series of hyoidean gill plates, and scale growth that originates near the caudal peduncle; these features suggest a relationship to acanthodians. Prior to this study, both authors conducted separate cladistic analyses which resulted in differing tree positions for L. pygmaeus and its relationships within the Acanthodii. However, both analyses did agree that there is no evidence allying L. pygmaeus to the traditional “climatiid” acanthodians contrary to previous historical classifications.

    Mid- to Late Palaeozoic sharks and holocephalans display a wide range of armour, with bodies that range from sleek, pelagic forms to slow-swimming, chimaeroids or ray-like bottom dwellers. Despite this Late Palaeozoic diversity, there still is an expectation that early chondrichthyans will be anatomically like later species. Recent discoveries from eastern Canada (Doliodus problematicus), and several heavily spined fishes from the MOTH locality in the Northwest Territories, including Kathemacanthus and Seretolepis, described here, challenge this expectation. These fishes show scale and endoskeletal features thought to be characteristic of chondrichthyans, yet they have paired fin spines, anal fin spines, and in some cases rows of prepectoral and prepelvic spines as would be expected from primitive acanthodians. Kathemacanthus and Seretolepis do not fit neatly within the cur- rent taxonomy, demonstrating that previous distinctions between acanthodians and chondrichthyans, including scale-based criteria, fail to account for the diversity being discovered in the fossil record.

    Two new acanthodian taxa are described. The ischnacanthid Xylacanthus kenstewarti is based on large, dentigerous jaws, and Granulacanthus joenelsoni is based on isolated spines. The isolated remains of these species are similar in that they both possess pustulose denticles or tubercles, either on the mesial ridge (X. kenstewarti) or on the fin spines (G. joenelsoni). Jaws of X. kenstewarti are similar in size to those of Xylacanthusminutus, Ischnacanthus kingi, and I. wickhami and smaller than those of X. grandis. The jaws of X. kenstewarti are most similar to those of X. minutus, but are distinguished from this and other ischnacanthid species by a tapering patch of pustulose denticles that is widest midway along the jaw, mesial denticles that are simple blisterlike structures, the monocuspid, striated primary teeth that are subcircular in cross section, and a posterodorsal process that is enlarged. The spines of G. joenelsoni have distinctive tubercular ornamentation. Tubercles, or nodular ornaments on fin spines, are characteristic of primitive acanthodians, but the slender shape of the spines, the low number of spine ribs, and the fine striations posterior to the main ribs of each spine suggest that G. joenelsoni is a relatively advanced acanthodian. Xylacanthus kenstewarti and G. joenelsoni are from the Silurian (Wenlock or Ludlow) of the southern Mackenzie Mountains. Xylacanthus kenstewarti represents the earliest representative of the genus, the earliest unequivocal remains of a gnathostome from the Mackenzie Mountains, and extends the known geographical range of the genus from the Mackenzie Mountains east to Spitsbergen.

    An acanthodian, Tetanopsyrus lindoei gen. et sp. nov., is described. All specimens are from Lochkovian of northwestern Canada. The body is covered with unornamented, flat scales, with two finely noded dorsal spines, finely noded anal, pelvic and pectoral spines, a high scapulocoracoid, and toothless jawbones with large, flat, crushing surfaces. Tetanopsyrus lacks pectoral dermal plates and intermediate pre-pelvic fin spines. Tetanopsyrus is classified in the new family Tetanopsyridae, and possible relationships of the family to diplacanthids are discussed.

    Specimens of two new fish species were collected from the Lower Devonian ichthyofauna of the Mackenzie Mountains, Northwest Territories, Canada. These two species are interesting in that they have monodontode scales, lack teeth, and have an unossified axial, visceral, and appendicular endoskeleton. These characteristics have been suggested to be primitive for jawed fishes. However, the new taxa have combinations of median and paired fin spines which are similar to those of acanthodian fishes. The new taxa show no obvious characteristics to suggest relationship to any particular group of acanthodians, and for the moment, we will not try to determine their relationships, but to use them as outgroups in an analyses of relationships within the class Acanthodii. Our cladistic analysis results suggest that climatiiform fishes are basal relative to acanthodiform and ischnacanthiform taxa. However, in contrast to previously published analyses, the order Climatiiformes appears paraphyletic relative to the other two acanthodian orders. Lupopsyrus pygmaeus is placed as the basal-most acanthodian species, Brochoadmones milesi, Euthacanthus macnicoli, and diplacanthids are relatively derived “climatiiform” fishes, and the heavily armored condition in Climatius reticulatus and Brachyacanthus scutiger appears as a uniquely derived state and not primitive for all acanthodians. In addition, Cassidiceps vermiculatus and Paucicanthus vanelsti seem to be related to acanthodiform fishes based on fin spine structures. Cassidiceps vermiculatus originally was placed with climatiiform fishes in the original description. Given our character coding, we identified several primitive characteristics which were retained in relatively derived acanthodian taxa.

    A mesacanthid acanthodian, Promesacanthus eppleri n. gen., n. sp., is described based on specimens collected from the Lower Devonian (Lochkovian) Manon-the-Hill locality of the Mackenzie Mountains, Northwest Territories, Canada. The head and body resemble that of other mesacanthids, but unlike all other acanthodiforms, this new taxon has a small prepectoral spine anterior to the pectoral fin spine. This new mesacanthid also possesses ornamented, blade-like hyoidean gill covers, enlarged lobate head scales, fin spines with ribs and fine striations, a scapulocoracoid with a triangular coracoid portion and a dorsal blade which is elliptical in cross section, procoracoids that articulate with a rounded fossa on the anteromedial face of the scapulocoracoids, and jaws which articulate at a simple, single joint. Mesacanthids are thought to be basal among acanthodiforms and are grouped based on a phenetic argument and their shared retention of features which likely are primitive for acanthodiforms (most notably, enlarged head scales, blade-like hyoidean gill covers, and a single pair of prepelvic spines). Based on overall similarity, P. eppleri n. gen., n. sp. appears most similar to Mesacanthus mitchelli, but the relationships of P. eppleri n. gen., n. sp. within the Mesacanthidae have yet to be determined with a cladistic analysis.

    The acanthodian Paucicanthus vanelsti gen. et sp. nov. is described from six body fossils from Lower Devonian (Lochkovian) rocks of the southern Mackenzie Mountains, Northwest Territories, Canada. This new species is unique among acanthodians in that it lacks both pectoral and pelvic fin-spines. In the absence of fin-spines, the leading edges of the pectoral and pelvic fins are reinforced by enlarged scales. The anatomy of the acanthodiform Traquairichthys pygmaeus is similar to P. vanelsti in that both lack pelvic fin-spines, although T. pygmaeus also lacks pelvic fins. Similarly, the acanthodian Yealepis douglasi lacks both paired and median fin-spines, and its anatomy resembles that of P. vanelsti based only on the loss of paired fin-spines. The lack of paired and (or) median fin-spines in these three taxa contrasts with the widely held view that acanthodian fins all were preceded by spines. The anatomy of P. vanelsti also is similar to that of the acanthodian Brochoadmones milesi in that both have a completely unossified endoskeleton, slightly elevated pectoral fins, and deep, compressed bodies. The median fin-spines of P. vanelsti have an anterior leading edge rib followed by a field of fine striations. This striated ornamentation coupled with few leading edge ribs also is seen on fin-spines of Cassidiceps vermiculatus and primitive acanthodiform acanthodians (e.g., Mesacanthus and Lodeacanthus species). I tentatively suggest that this fin-spine ornament indicates relationship between P. vanelsti, acanthodiform acanthodians, and C. vermiculatus. However, a cladistic analysis is required to test whether or not the characteristics such as fin-spine loss, unossified endoskeleton, elevated pectoral fins, deep compressed bodies, and (or) median fin-spine ornamentation are synapomorphies within the Acanthodii or evolved convergently within the class.

    New anatomical details are described for the acanthodian Brochoadmones milesi based on nearly complete body fossils from Lochkovian rocks at MOTH, Mackenzie Mountains, Northwest Territories, Canada. The body and caudal peduncle are deep, and a prominent nuchal hump is present before the dorsal fin origin. The caudal fin is correspondingly deep and ventrally, the caudal fin lies close to and is partly joined to the slender anal fin. A delicate pectoral fin trails the flattened pectoral-fin spine where previously known specimens showed only a fin spine resembling a bivalve shell. Seen for the first time in any vertebrate, each of the six pairs of prepelvic spines supports a small, scale-covered finlet. Both prepelvic spines and scalecovered finlets increase in size posteriorly. The series of paired prepelvic finlets originates ventral to the branchial chamber and anteroventral to the pectoral fin, and extends posteriorly as far as the pelvic fins. The scales of the body and fins are thin and flat, without obvious evidence of ossified basal tissue or entry point for vascular tissue. The main lateral-line canal passes dorsal to the branchial chamber and terminates at the trailing edge of the caudal fin web. Lateral-line scales are thicker than body scales and show concentric growth zones. Scales from the dorsal midline of the caudal fin are also thicker, showing few superpositional growth zones in the mesodentine of the crown together with what appears to be cellular basal tissue. The structure and position of the pectoral spine and fin, the extremely thin body scales, the slender anal fin, and the prepelvic finlets are all unique and appear to be autapomorphic features compared to those of other acanthodians. Brochoadmones milesi is derived relative to other fishes traditionally classified in the Climatiiformes. Kathemacanthus rosulentus is removed from the Brochoadmonoidei, leaving only B. milesi in a monotypic suborder.

    An undescribed genus and species of pachyosteomorph arthrodire, Squamatognathus steeprockensis gen. et sp. nov., from the Middle Devonian (Eifelian) Elm Point Formation in Manitoba is described. It was found in the LaFarge Quarry at Steep Rock, Manitoba, and is represented by the anterior portion of a large, right inferognathal with a large terminal cusp, similar to inferognathals of the family Dinichthyidae. It has unique sculpture on the lingual surface not reported from any other dinichthyid arthrodire.

    Fish remains from the Middle Devonian (Late Eifelian) were found in three limestone quarries in the Elm Point and Winnipegosis formations, near Lake Manitoba, south-central Manitoba. The arthrodire material represents a taxon previously unknown from Manitoba. Eastmanosteus lundarensis sp. nov., is described based on an articulated, nearly complete cranial roof and incomplete cranial roof, a suborbital plate and thoracic shield fragments. E. lundarensis is the oldest representative of the genus, and is the first record of the genus in Canada. E. lundarensis is most similar to the other North American and European Eastmanosteus species rather than the two Australasian Eastmanosteus species and Golshanichthys.

    Trawl samples along the British Columbia coast between 1999 and 2006 revealed many previously undetected species living in deep water. This increase in knowledge underscores the importance of survey collections for non-game fishes, which form a vital link in marine ecosystems. Although there are few records of albuliform fishes in the eastern North Pacific Ocean, Aldrovandia oleosa (Halosauridae) and Polyacanthonotus challengeri (Notacanthidae) are known from British Columbia. The notacanthid Notacanthus chemnitzii is known from off California, Oregon, and Alaska, but until now it was not confirmed from British Columbia. The ranges of these 3 albuliform fishes are updated in this paper. Until now, 7 species of true eels (Anguilliformes) were known to exist in British Columbia based on literature records and museum specimens; Nemichthys scolopaceus, Avocettina infans, Serrivomer jesperseni, Xenomystax atrarius, Thalassenchelys coheni, Venefica ocella and V. tentaculata. Two synaphobranchids, Synaphobranchus affinis and Histiobranchius bathybius, also occur in adjacent waters of Alaska, and until recently S. affinis was thought to exist in British Columbia based on a misidentified specimen. This paper provides a re-identification of the Synaphobranchus from British Columbia as the 1st record of S. brevidorsalis for the province and also adds Nemichthys larseni and Cyema atrum (Saccopharyngiformes) to the diversity of eels now known from British Columbia waters. We also provide significant range extensions for Serrivomer jesperseni, Thalassenchelys coheni, and Venefica tentaculata along the British Columbia coast.

    Cusk-eels and brotulas of British Columbia have been poorly studied, and until now, there were published records of only Spectrunculus grandis and Brosmophycis marginata from our waters. However, a single specimen of S. crassus has been identified from among the few S. grandis from British Columbia held at the Royal British Columbia Museum. Furthermore, increased sampling effort from deep-water surveys, shrimp surveys, and the commercial fishery revealed 5 additional cusk-eel species and 1 brotula offshore of British Columbia. Two specimens of Chilara taylori were collected from the southern Strait of Georgia at depths of 78 to 109 m. A single specimen of Acanthonus armatus was taken from near Triangle Island at 1778 m and is the 1st record for the eastern North Pacific Ocean. One specimen of Cherublemma emmelas was found at 1097 m in Kyuquot Canyon, west of Vancouver Island; 4 specimens of Bassozetus zenkevitchi were collected from depths of 1909 to 2125 m west of Vancouver and Graham islands; and a specimen of Cataetyx rubrirostris from 2000 m and a Porogadus promelas from 1967 m were taken in Queen Charlotte Sound, east of the Tuzo Wilson Seamounts. Because of increased sampling effort from 1999 to 2007, we now understand the number of cusk-eels and brotulas in British Columbia to be 9 species.

    Between 1999 and 2006, the Department of Fisheries and Oceans performed deep-water sampling and discovered new range records for many species of fishes. Here we report 3 species new to British Columbia: Idiacanthus antrostomus, Benthalbella linguidens and Scopelengys tristis, and update the known ranges of 7 additional species (Argyropelecus sladeni, Sternoptyx pseudobscura, Aristostomias scintillans, Opostomias mitsuii, Bathophilus flemingi, Scopelosaurus adleri, and Magnisudis atlantica) in British Columbia waters.

    Deep-sea anglerfishes were taken in trawls between 1999 and 2006. The 3 most commonly encountered species, Oneirodes thompsoni, O. bulbosus and Chaenophryne melanorhabdus, were known already from British Columbia waters, and here we report significant range extensions for these 3 species. Ceratias holboelli also had been reported from British Columbia, but until now, no specific collection localities had been published. In addition, 3 oneirodids (Oneirodes eschrichtii, O. acanthias and Chaenophryne longiceps), Melanocetus johnsonii (Melanocetidae), and Cryptopsaras couesii (Ceratiidae) are reported for the 1st time from British Columbia.

    Single specimens of Finescale Triggerfish (Balistes polylepis) and Louvar (Luvarus imperialis) were found in British Columbia’s coastal waters in 2014. Both B. polylepis and L. imperialis normally are found off southern-most California and Baja California. Although a stray B. polylepis was caught as far north as Metlakatla, Alaska, during the 1982–1983 El Niño event, and L. imperialis is known to stray north along the Washington coastline, these 2 new specimens represent 1st records for British Columbia. Both probably moved north during the warm-water anomaly that has persisted along the North American coast since 2013.

    Allium acuminatum

    We are fortunate to have six species of attractive native flowering onions in British Columbia. Nodding onion (Allium cernuum) is widespread. But Hooker’s onion (Allium acuminatum) or taper-tip onion is uncommon BC but widespread on the con­tinent.

    Hooker’s onion of the Lily Family (Liliaceae or more recently Amaryllidaceae)   grows as a bulbous perennial. The generally creamy to light brown true bulb has the shape of a slightly flattened globe. It is small, less than the size of a thumb nail on average 1.5 cm (0.6″) across. Wild, bulbs occur in clusters of about the size that would fit easily into the palm of a hand. Each bulb bears two to four channeled leaves which are predominantly grey-green with a reddish base. At first the leaves stand erect, but by the time they reach 15 cm (6″) long they reflex. By onion standards, the leaves seem nearly insignificant reaching a maximum of scarcely half a centimetre across and 30 cm (12″) long or less. Leaves usually dry out and break off by flowering time.

    Hooker’s onion flower from bulbs grown in pot by Richard Hebda. Photo Dr. Richard Hebda.

    Flowers are borne on a firm rounded stalk which ran­ges from 10-30 cm (4-12″) tall. Two papery bracts sur­round the bud which contains five to 30 flowers. The blooms sit upon more or less equally long stalklets (called pedicels by botanists), so that the head forms a loose umbel reaching about 7.5 cm (3″) across. Each flower consists of six perianth segments, three petal-like sepals and three petals. The lance-shaped petal-like sepals reach about 1 cm (0.4″) long. Their tips notably reflex espe­cially with age. Six short an­thers surround a slightly crested ovary which bears a clearly visible stigma. Mostly the sepals and  petals are pink, but may vary from intense rosy purple to nearly white.

    In mild coastal climates the first signs of life appear in early February as leaf tips emerge. In Victoria, this occurs well before the end of winter, and sometimes the snow and frost may freeze back young shoots. During April, leaves continue to get longer and reach their maximum length. By the end of the month the first flower stalks poke out of the ground reaching up to 30 cm (12″) tall in June when flowers open. Capsules split in July to reveal black seeds which are easy to harvest by sharply shaking seed heads into a bag.

    Hooker’s onion ranges from southern British Columbia to northern California and eastward to Colorado and Wyoming then southward to Arizona. In BC its distribution includes dry parts of Vancouver Island and the adjacent mainland extending into the Fraser Canyon. In our region Hooker’s onion clearly favours dry rocky sites, typically growing in pockets of soil on rocky knolls and coastal headlands. Sometimes it survives in only about 5 cm (2″) of mossy crust cover over bedrock, yet it flowers reliably every year. Occasionally this onion thrives under Garry oaks (Quercus garryana), albeit in very shallow stony soil.

    These bulbs are little cultivated and rarely available, yet they thrive under appropriate conditions and pro­duce a pleasing display. The site must be in full sun, sharply drained and with a sandy soil. Avoid summer watering. Rock gardens, the front of dry peren­nial beds and pots of gritty soil suit Hooker’s onion well in the milder parts of southern B.C.

    Plant bulbs about 5 cm (2″) deep about 5 – 7.5 cm (2-5″) apart so that the flower heads touch. Divide the clusters every five to ten years in late summer.

    Order Hooker’s onions from specialist native plant suppliers or grow them from fall-sown seed. Do not dig this relatively rare plant in the wild.

    First Nations of coastal British Columbia savoured various wild onion species including Hooker’s onion. Bulbs were eaten raw or steamed in great pits. In some areas the pits were lined with pine boughs and covered with lichens and alder boughs. Bulbs and shoots have a mild onion flavour and smell.

    Hooker’s onion may be hardy to as low as zone 4 in BC, but its natural distribution suggests zone 5 or higher. We have several native onion species in the Native Plant Garden of the Royal B.C. Museum which flower mainly in June

    Heracleum maximum

    Many of the vegetables we eat came originally from Europe, Asia and Latin America. The aboriginal peoples of British Columbia were un­familiar with these food plants, ne­vertheless they feasted on several in­digenous green vegetables. The most widely eaten among these was the cow-parsnip (now called Heracleum maximum, recently known as Heracelum lanatum), also referred to as Indian rhubarb or wild rhubarb.

    Cow-parsnip belongs to the Parsley Family (Umbelliferae or Apiaceae) and grows in the form of a gigantic perennial herb. A thick hollow stem stands 1-3 meters (40-120”) tall and bears large broad leaves. Stems are lightly ridged and woolly. Each leaf is divided into three segments with coarse teeth. Leaves occur at the base of the stalk and along it. Sometimes you will see big swollen structures at the leaf bases. These are flower buds just waiting to emerge.

    The stem top is crowned by several handsome, flat-topped flower heads. Each head consists of numer­ous umbrella-like clusters of small white blossoms that vary in di­ameter from 0.5 to 1 cm (0.2-0.4”) across. There are five creamy-white petals in each flower. The blooms circling the outside of each cluster are usually larger and often slightly irregular in form. Five spin­dly stamens bearing greenish anthers sur­round a greenish pistil. Cow-parsnip produces robust flattened seeds which remain on the stalk well into the summer.

    Cow-parsnip thrives in rich moist soil along streams and rivers, road­sides and in meadows. You will often find it forming large colonies. It has a wide climatic tolerance, growing from sea level to the alpine zone. The Parsnip River in east central British Columbia is named after this plant. Cow-parsnip may be seen almost any­where in North America in suitable habitats.

    Almost every First Nations group in Brit­ish Columbia ate cow-parsnip as a green vegetable. Before the flowers appeared in spring, young stalks and leaf stems (petioles) were peeled and eaten raw.  Sometimes they were boiled, steamed or roasted. Bruised cow-parsnip plants emit a strong smell but the stems are sweet and juicy, somewhat like celery. Coastal people ate cow-pars­nip with eulachon fish grease.

    According to Saanich Elders Violet Williams and Elsie Claxton, the stalks had to be collected for eating before the flower buds opened. Otherwise they were tough to chew and tasted too strong.

    Be aware that members of the parsley family, especially water hem­lock (Cicuta douglasii) and poison hemlock (Conium maculatum) con­tain terribly strong poisons which can kill a human. You must be certain that the plant you intend to eat is a cow-parsnip.

    Cow-parsnip plants can make a bold addi­tion to your garden but you must give them room. They are best raised from seed, collected as soon as it is ma­ture, and planted in a rich moist soil. You may be able to carefully transplant very young seedlings too, but I su­spect that this technique is not often successful.

    Cow-parsnip has one characteristic you should be wary of. Like its gigan­tic relative, giant cow-parsnip or hogweed (Heracleum mantegazzianum), cow-parsnip contains chemicals that may cause sev­ere skin inflammation known as dermatitis. The sap of the plant has particularly strong activity. Ul­traviolet rays from the sun activate the compound and may cause the skin to redden and even produce per­manent discoloration. Not all people are so affected but be warned to han­dle the plant carefully especially on a hot sunny day.

    The plant supposedly obtained its name after the Greek god Heracles (Hercules). The previously-used species name “la­natum” refers to the “woolly” leaves and parts of the stem.

    As you see great stretches of cow- parsnip along our province’s high­ways, think of it not as a roadside weed but as a valuable food of British Columbia’s First Nations. Cow-parsnip is hardy to zones 2-3 in Canada.

    Oxyria dignya

    Wild nibbles make a pleasant treat while hiking in the bush. Most often the tasty treat con­sists of berries of one sort or anoth­er, but the occasional green pro­vides a refreshing chew. Mountain sorrel (Oxyria digyna) can spare a leaf or two for the adventurous alpine wanderer.

    This delightful hardy herb grows from the top of a tenacious stout tap root. Fleshy, kidney-shaped leaves arise on leaf stalks attached to a short erect stem. Leaf blades range from 1-5 cm (0.4-2”) wide, their stalks 4-8 cm (1.6-3.2”) long. Normally they are coloured bright green but may turn greenish red  as the season advances or in really tough sites. There is usually also a single leaf on the stem. The leaves have a sour, but refreshing, acid taste, hence the botanical name Oxyria derived from Greek the word “oxys” which means sharp.

    Like all members of the Buckwheat Family (Polygonaceae), mountain sorrel has small hard- to-see flowers. They cluster irregularly along a 10 to 60 cm (4-24”) tall, narrow flower stalk. Each green to reddish flower consists of four tiny “petals” joined at the base. Two of the petals are keeled, the other two are not. Inside the flowers reside six sta­mens and a two-parted pistil. Flowers appear from June to August accord­ing to elevation and latitude. At maturity, the fruit is broadly winged, turning a showy reddish purple. The fruit is mostly translucent and literally shines when the sun’s light passes through it.

    Mountain sorrel ranges through­out the mountains of British Columbia and Alberta, south to New Mexico and California, and north through Alaska and the Yukon and across the Arctic.  It also inhabits most of the mountains of Asia and Europe. In our province, moun­tain sorrel thrives in alpine scree and rock crevices and can be found in suit­able habitats on almost every high mountain, to the elevation where no other plants can survive.

    Surprisingly this delightful little moun­tain nibble will grow in lowland rock gar­dens. It needs a relatively moist gritty run for its root and full sun. In our coastal lowlands mountain sorrel probably needs to be sheltered from full scorching mid-day heat. Plants are best raised from seed sown carefully in the site where it is to grow. Sow the seeds in very stony and moist, but not rich, soil.

    Okanagan First Peoples ate fresh raw leaves, but never too many at a time because the oxalic (sour) acid in the plant can be harmful if taken in large quantity. This sorrel contains abundant Vitamins A and C and was used against scurvy in Europe. Like other wild and cultivated sorrels it was widely cooked as a pot herb. A few leaves add a spritely bite when mixed into a salad.

    This amazing plant has an incredible story to tell about the glacial history of our province. Studies of the chloroplast DNA by Royal BC Museum and University of Victoria reveal that the genetic makeup of the alpine herb in BC is surprisingly diverse. Within BC, the high diversity and the occurrence of ancient genetic forms suggest that high elevation mountains in the north escaped the last glaciation, contrary to widely accepted thinking.

    Mountain sorrel is hardy to zone 0 in Canada. In fact,it is pretty much the hardiest of all plants in the world.

    Rubus parviflorus

    Highly ornamental flowers of British Columbia’s native thimbleberry. Photo by Dr. Richard Hebda. Saanich, Vancouver Island, British Columbia.

    British Columbia is home to shrubs with many uses. For ex­ample our Oregon-grapes (Berberis or Mahonia species) make excellent year-round or­namentals, whose fruits produce tasty jelly. Few of our shrubs however can match the thimbleberry of the Rose Family (Rosaceae) for utility. Not only does it have tasty fruits, but this shrub produces ed­ible shoots, soap from its stems, and is an attractive and widely-adapted subject for gardens.

    Thimbleberry forms waist- to head-high thickets of numerous erect stems. The stems are thorn-free, unlike the closely related raspberries and blackberries. The bark is distinctively flaky and especially hairy on new growth. Maple-like leaves, 10-30 cm (4-12″) across occur at the ends of the stems. Each one has seven to nine lobes and a texture like soft sandpaper.

    Open flower clusters, containing three to eleven blooms develop at the ends of the branches. Each bright white flower can be as wide as 7-8 cm (3″) across. Five long greenish sepals surround five clear white oval petals. A ring of many stamens encircles a central fleshy dome. This dome is the swollen end of the stem, and attached to its surface are numerous tiny greenish pistils. Once the egg in each pis­til is fertilized, the pistil transforms into a tiny red fruit with a hard seed inside. The mass of little fruits forms a shallow “thimble” over the central dome, looking like a thin raspberry. The velvety thimbles are somewhat dry but usually taste very sweet.

    Thimbleberry grows throughout much of British Columbia except the far north. On the con­tinent you can encounter it from Alaska to northern Mexico and eastward to Ontario and Colorado. Typical haunts include open sites, often at the edge of woods, roadsides and shorelines. Surprisingly thimbleberry inhabits both moist and dry sites and occurs across a wide range of elevations from sea level to the high subalpine zone; a widely-adapted plant. Notably, it is one of the species to colonize early after disturbance par­ticularly along highways.

    Thimbleberries are excellent sub­jects for naturalizing in corners of suburban lots. They seem not to be choosy about soil conditions and will grow on raw unprepared surfaces. In fact, in some places they will appear on their own, presumably inoculated from bird droppings. They will grow in full sun to part shade. These shrubs quick­ly form thickets, generating wildlife cover and stabilize the soil. Butterflies love the flowers and birds relish the fruit.

    You can often purchase thimbleberries from the local nursery or garden centre by asking them to order it in. There are several suppliers in British Columbia. This native species has recently become available through mail-order from seed and nursery catalogues. Thimbleberries can be raised from seed sown in place in the garden in the fall for germination in the spring. Rooted offset stems will also transplant in a dormant state.

    First Nations of British Columbia used thimbleberry for many purposes. Fruits were eaten fresh by most groups or pressed and dried into cakes for later. People of the west coast of Vancouver Island gathered canoe-loads of sweet and juicy spring shoots, peeled and ate them raw. Okanagan people lined their steam-cooking pits with the large leaves. Shuswap Carrier First Nations used the leaves to separate dif­ferent types of berries in a picking bas­ket. The Cowlitz of nearby Washington State boiled the bark for soap. Today hikers nibble on the wild fruit during their wanderings.

    The technical name “Rubus” is based on an ancient Roman name for a related plant. The species name “par­viflorus” means “small-flowered”, hardly appropriate for the large attrac­tive blooms produced by thimbleberry.

    Thimbleberry is a widely adapted native shrub for most gardens in the province; fruit, vegetable, ornamental and soil healer all rolled into one. It is hardy to Zone 3 in Canada.

    Malus fusca

    Have you sometimes wondered what the wild ancestors of our highly-bred food plants may have looked like? The wild apples that spring up in hedgerows on Vancouver Island are often as large as our cultivated forms. Our cultivated crab apples, though they may seem closer to the wild than regular apples, are still the result of breeding. British Columbia’s native Pacific crab apple (Malus fusca or Pyrus fusca), however, may look very much as the ancestors of cultivated apples did many thousands of years ago. Bearing scented blooms, edible fruit and growing to a small stature, it has much potential as a garden and landscape plant.

    Pacific crab apple, also known as Oregon crab apple, forms shrubs to small trees from 2 to 12 m (6½ to 40 ft.) tall. Plants branch widely and often form extensive thickets.  Distinctive, spine-like, short shoots line the branches but are not nearly as vicious as those of black hawthorn (Crataegus douglasii) or English or common hawthorn (Crataegus monogyna). The grey bark becomes scaly or deeply fissured with age. Oval and pointed leaves look as if they are a cross between those of the domesticated pear and apple. These weakly-toothed leaves sometimes may be lobed near the base.

    Delightful blooms have an apple-blossom scent and appear in flat-topped clusters in the spring. Most flowers are white or creamy, but sometimes they take on a warm pink blush and can be very showy. Each flower is about 2 cm (slightly less than an inch) across. The five petals extend well beyond the cluster of stamens in the centre. As in apples and pears, the ovary is inferior, meaning that it is located below, not on the inside of the petals and sepals. In late summer, bunches of oval to cylinder-shaped fruits dangle from long red stalks. Each fruit is about the size of the end of your little finger. An open-grown tree can be “dripping” in fruit similar to some cultivated crab apples. At first the fruits are green and shiny but within a few weeks they turn yellow, pinkish and sometimes even purplish-red. Ripe fruit clusters, especially those well exposed to sunlight, are very attractive. The fruit tastes pleasantly tart when coloured up. After frost it turns brown and mushy but sweet.

    Pacific crab apple occurs along the British Columbia coast well up many of the main river systems from Alaska to Vancouver Island and on the adjacent mainland to elevations as high as 800 m (2600 ft.). The full geographic range extends all the way from the Aleutian Islands to northern California. The natural habitat tends to the moist side and includes damp woods, stream sides and coastal bogs. These amazing bog trees resemble large gnarled and twisted “creatures” that seem to hail from some distant prehistoric times. They also occur frequently just inland of the ocean shoreline, especially behind beaches and at the edges of estuaries, which suggests that they tolerate salt spray. On some outer coast islets, exposed to the full influence of the sea, our native crab apples may be the only broad-leaved tree among a mass of Sitka spruce (Picea sitchensis) and other conifers.

    The hard wood of the Pacific crab apple was widely used along the coast. From it, First Nations people fashioned tool handles, bows, sledgehammers and smaller items, such as spoons and fish hooks. The Nisga’a of northwest B.C. pegged their house boards in place with crab apple wood. The fruit was harvested in early fall and eaten fresh or stored in boxes under water. Apparently, this stored fruit sweetened and softened over time. Medicines, often in combination with other plants, were made from the bark. These medicines were used for a range of internal and external ailments such as stomach problems and skin complaints. The bark and other parts of the tree release hydrogen cyanide, so use only with caution. The flesh of the fruits apparently does not produce much cyanide.

    In the garden, Pacific crab apple features best as a specimen tree in an open area. Slow growing, the crown eventually spreads farther than the tree reaches in height. Leaves turn gold and then even red in the fall and combine very attractively with the colours of the ripening fruit. The fruit makes excellent jelly and can be added to other jellies as a natural source of pectin. Wild birds enjoy the ripe fruit, too. Closely planted trees can from a fine dense hedge, and might be good candidates for hedges near the seashore. Plants are best raised from seed sown in the fall in pots and left outside. Seedlings normally take two years to become large enough to plant out.

    Up to now the native plant literature has not given much attention to Pacific crab apple, but it has considerable possibilities. The attractive form, flowers and potential for heavy wild fruit production all point to a valuable native species for the garden landscape.  Pacific crab apple is hardy to zones 5-6 in Canada.



    Achillea millefolium

    Details of yarrow flowers, taken along a roadside in Colwood BC in December. The petals of the white ray florets have been twisted by frost. The brownish grey disk florets are visible in the centre of each little flower head. Photo by Dr. Richard J. Hebda.

    Numerous plant species release strong scents when brushed. In the past, these smells were taken as a sign that the plant may have medicinal prop­erties. Even today, some popular remedies still depend on aromatic compounds from plants. For example several brands of cough candies con­tain derivatives of the eucalyptus plant notable for its distinctly flavoured  oil. Many strongly-scented plants thrive in British Columbia, including common or white yarrow (Achillea millefolium), a species well known around the world for its healing value.

    Yarrow, a member of the Aster Family (Asteraceae), grows as a herbaceous perennial with leaves and flowers arising from creep­ing underground or near-surface root stocks. The aromatic fern- or feather-­like leaves are finely divided and feel soft. Leaves cluster mostly at the base of the flowering stalk; these leaves are mainly 10-15 cm (4 – 6 inches) long. Many soft small hairs cover the plant making it appear greyish-green.

    Tiny flowers crowd into small flower heads, that are further arranged into flat-topped clusters on stalks up to 100 cm (40 inches) tall. Each small flower head in the cluster consists of three to eight tiny ray flowers with a strap-shaped petal, and disk flowers with only reproduc­tive parts. The flowers are white to pinkish and appear from May to October depending on the local cli­mate. On south Vancouver Island they even bloom as late as December. The flower tops dry and turn brown by the end of summer, produc­ing many one-seeded, smooth and flattened fruits.

    Yarrow occurs from low to high elevations and often becomes weedy in disturbed settings. This herb thrives in coastal meadows and the arid sage brush steppe of the interior of BC. We also encounter it often in the lower part of the alpine zone during our studies of BC’s mountain flora. You can find yarrow throughout British Columbia and over much of North America. It also occurs across northern and central Europe and Asia.

    Yarrow has been valued as a gar­den plant for centuries.  Various forms are available for you to purchase as plants from garden centres and through mail order. Seeds of many colourful selections, especially red and pink shades, are sold through seed catalogues. Plants are easily raised from seed sown into light seed compost or peat pellets in the fall or spring. Rhizome divisions transplant easily too.

    Dwarf varieties thrive in rock gardens. Larger types are suitable for mixed borders, perennial beds and the cutting garden. When mowed reg­ularly, yarrow forms a soft-scented ground cover especially valuable for dry lawns. Yarrow is also an excellent subject for the xeriscape garden. This tough plant  has been suggested for erosion control on slopes too.

    Many First Nations Elders of the B.C. inte­rior value yarrow as a medicine, espe­cially to treat sores. Ulkatcho people of the west Chilcotin soak the leaves in hot water, then apply them in a poultice to sore mus­cles. This same poultice can also be used to treat saddle sores on horses. Washed and crushed roots were rec­ommended for toothaches. Various teas and concoctions were prepared for internal problems and as a gener­al tonic. Fresh leaves crushed and rubbed on the skin or put to smoke away in a fire act to repel mosquitoes.

    Herbal users should be aware that yarrow is “phototoxic.” Skin exposed to crushed or rubbed yarrow may become irritated when exposed to strong sun.

    The name Achillea derives from the Greek hero, Achilles, who well knew the medicinal properties of the plant. The finely divided leaves are responsi­ble for the species name “millefolium” meaning “thousands of leaves”. Yarrow is hardy to zone 2 in Canada.


    Eriophyllum lanatum

    Traditional garden plants often have substitute native species, often hardier, less invasive and easier to manage. The native tall Oregon-grape (Mahonia aquifolium) is an excellent alternative to many cultivated shrubs for mass bedding for example. With a few exceptions, native perennials have yet to replace imports or join the display in more formal settings. Woolly sunflower (Eriophyllum lanatum) is a multi-use native prospect for British Columbia and the west coast of North America.

    Woolly sunflower is a spreading fibrous-rooted perennial herb, resembling a restrained version of dusty miller (Artemisia stelleriana). Several hairy stems scramble upwards from the base and bear numerous much-divided silvery leaves. Robust mature plants reach to 60 cm (24”) tall but most often wild specimens rise about 30 cm (12”).


    Eriophyllum lanatum (Common woolly sunflower). Photo by Dr. Richard J. Hebda.

    Buttery yellow blooms, 5 cm (2”) wide, face brightly upwards like miniature sunflowers. As is typical of the Aster Family (Asteraceae) the flower is actually a flower head of numerous florets. The rays or outside flowers have narrowly oval petals 1-2 cm (0.4 -0.8”) long. About 8-13 of these frame a disc of tightly-packed inner florets without the showy rays, just as you find in a typical garden marigold. Flowers are borne singly on long stems rising well above the silvery blue foliage. Flowers appear from early May to August, generally in June in southwest BC.

    Woolly sunflower populates relatively dry open habitats such as bluffs and rocky slopes, largely being confined to low to mid elevations. In BC, it ranges along the coast southward from Vancouver Island and the adjacent mainland, and inland to the Fraser Canyon with a population in the southern Interior. In the United States, the range extends well into California and eastward to Montana and Wyoming. The inland occurrences of woolly sunflower suggest a strong potential for BC interior gardens.

    This marvellous plant has several garden uses. First, it thrives in the dry and sunny rock garden, even on poor stony soil. Although it may take a year or two, your plants will become established, persist, and flower from year to year. A patch placed in raw subsoil mixed with gravel has grown for more than 15 years at the Royal BC Museum Native Plant Garden. I have spread it widely along my driveway where it thrives! Woolly sunflower grows well in pots too, as a perennial surrounded by annuals planted freshly year after year. April Pettinger and Brenda Costanzo in their excellent book Native Plants in the Coastal Garden recommend woolly sunflower for shoreline plantings, use in repeated drifts, and in containers. They also note its resistance to deer.


    Eriophyllum lanatum (Common woolly sunflower). Photo by Dr. Richard J. Hebda.

    Woolly sunflower is grown in many native plant nurseries especially in the western United States and is known even in Europe. You can propagate it by root cuttings in late winter, seeds sown in fall and crown divisions. I multiply my woolly sunflowers by pulling out rooted stems or digging out small plugs at almost any time of the year and replanting. Once in while pull out invading grasses and other weeds from the spreading mats.

    The First Nations people of the Thompson River region knew this species as either yellow flower or as “friend or relative” of the much larger and related Balsamroot (Balsamorhiza sagittata). In Washington State, dried flowers were used as love charms and the leaves could be rubbed on one’s face to prevent chapping.

    Eriophylllum lanatum is also known as Woolly Eriophyllum and Oregon Sunshine. In Canada it is hardy to Zone 5 meaning it likely will grow in many gardens throughout the south.

    Take a chance on the wild side and try growing woolly sunflower in your garden. Experiment with it as a replacement for silvery-leaved ground covers and enjoy the annual display of golden blooms.

    Empetrum nigrum

    Heathers (Calluna species) and heaths (Erica species) are popular ground cover plants worldwide. True heathers and heaths are not native to British Columbia, but many heather relatives and heather-like plants thrive in our province, some under harsh inland climates. Crowberry (Empetrum nigrum) (also known as curlew-berry and crake berry) is an excellent, extremely hardy, heather substitute that fulfils the role of ground cover and produces abundant attractive black berries.

    Crowberry plants consist of scrambling woody stems rising to 20 cm (8″) tall, and enveloped in wooly hairs and short evergreen leaves. Small roots anchor the stems into the soil. Often a mass of better developed roots associated with a loose crown in the middle of a patch provide a firm grip. Numerous needle-like leaves are arranged in alternate fashion or grouped in fours. These grooved leaves extend 4-8 mm (0.15-0.3”) long and have their margins rolled under.

    Tiny purplish flowers appear early in spring, scattered along the stem at the base of the leaves. There are male and female flowers, which sometimes occur on separate plants. Each flower has either one tiny ovary, or three purple stamens, sometimes with up to three purplish petals, all cupped in tiny sepals and bracts.

    Unlike the inconspicuous blooms, the shiny black bead-like fruits are easily visible and very attractive. These globe-shaped berries are fleshy and juicy, about half a centimeter (1/5 “) across. On loose leafy plants the berries often occur singly, spaced along the stems. On low growing plants they cluster in bunches and appear to nearly smother the plant. The berries contain large white seeds and are a favourite food of bears.

    Crowberries are widespread plants with a most hardy constitution. You can find them almost anywhere in our province in suitable habitats except in the dry lowland climates of the southern interior. Plants have been observed to nearly 2500m (about 7750 feet) above sea-level in BC. Crowberry’s geographical range extends across all of Canada, southward on the west coast to California and around the northern hemisphere. It is largely a plant of full sun environments. At low elevations, especially on the coast, it inhabits bogs and openings in bog forests. Inland you may encounter it in conifer forest openings and almost everywhere in the alpine tundra and subalpine turf as well as on dry rocky mountain knolls. Crowberry favours acid to very acid soils usually with abundant organic debris.

    This creeping shrub has great potential as a ground cover species in most BC gardens. It is especially suited to interior gardens in regions with cold harsh climates. On the coast it is better suited to open moist rock gardens or bog gardens where it will grow into a loose luxuriant mass of heather-like stems. Plants are most easily grown from root-bearing stem pieces planted in moist sandy peat soil until well rooted. Nursery material has also been grown from cuttings and fresh seeds sown in the fall. Crowberry is hardy to zone 1 in Canada.

    Crowberries were eaten widely throughout British Columbia. Anyone who has munched a crowberry on a wilderness hike knows they tend to be somewhat watery and slightly tart, but pleasant nevertheless. On the coast crowberries were mainly eaten fresh by Haida and Tsimshian peoples in whose lands they can occur in great abundance. Haida Elders thought that eating too many of them might lead to internal bleeding. In the northern interior many First Nations people ate the berries because they are available all winter long under the snow. Some Carrier people mixed the berries with bear grease. Berries were also prepared by mashing them and cooking with heated stones in spruce bark troughs. Dried mash was soaked in water and consumed later. Mixed with sugar the berries can be used for pies and jellies.

    Crowberries are an excellent heather-like ground cover for coastal and especially cool interior gardens, despite the absence of showy flowers. And unlike true heathers you can nibble tart fruit in fall and even in winter. So, enjoy this widespread native in the wild and maybe find a spot for it in your garden.

    Cornus unalaschkensis

    British Columbia forests are re­nowned for the trees they grow. Wi­thin these great forests there are other botanical treasures that live on the forest floor. Among these the bunchberries (Cornus  spp.) are among the most wi­despread.

    Bunchberries belong to the Dog­wood Family (Cornaceae) along with our provincial floral emblem the western flowering or Paci­fic dogwood (Cornus nuttallii) and red-osier dogwood (Cornus stolonifera). Bunchberries grow as low, carpeting herb-like shrubs. A root-stem system (rhizome) spreads just below the ground surface and from it arise 5-20 cm (2-8″) tall flexible stems. Each erect stem bears a pair of small highly reduced leaves about halfway up, and a whorl of 2-8 cm (0.8-3.2”) long oval leaves at the top. The leaves are usually dark green and somewhat glossy but may yellow in full sun. The veins appear to be well pressed-into the leaf sur­face. Tear through the leaf and you will see several thin whitish strands along the torn edges, a characteristic of dogwood leaves.

    A flower head develops in late spring to early summer at the top of the stem. Four to six modified leaves cal­led bracts surround the cluster of tiny flowers in the centre. Most people think that these white bracts are the petals but they are not. True flowers huddle cheek-to-jowl in a central clump. Each mini-bloom consists of a tiny toothed tube of greenish sepals which in turn surrounds a tiny funnel of four pur­plish petals. The pistil hides within the throat of the flower. Four spindly stamens poke out from the mouth. The berry-like fruits mature in late summer and early fall into a bright red bunch (hence the common name). Alaskan bunchberry differs from the common and widespread bunchberry (Cornus canadensis) which has greenish white petals and no well-developed leaves on the stem.

    Alaskan bunchberry haunts mo­ist old-growth forests and thickets of British Columbia’s coastal strip. It thrives on acid soils rich in humus, draping over rotting logs and crowd­ing under shrubs at the edges of bogs and in the sub-alpine zone. The geographic range of the species extends both north and south along the coast into Alaska and the northwestern Un­ited States. Common bunchberry re­places Alaskan bunchberry east of the Coast Mountains.

    Alaskan bunchberries were much savoured by First Nations people of the coast. The berries were eaten raw, with eulachon fish grease and with sugar. Haida occasionally steamed the fruit, mixed it with water and grease and stored it for the win­ter. Although the berries have a pu­lpy texture and a large seed, their taste is pleasantly sweet.

    Bunchberries make excellent gar­den subjects especially in moist sha­ded settings under trees and on the north side of buildings. They com­bine well with shrubby members of the heather family (Ericaceae) such as rhododendrons or azaleas. They need moist, airy and humus-enriched soil to thrive and do not enjoy warm sunny set­tings. We have grown bunchberries with tall ferns under a tree in the Native Plant Garden of the Royal British Co­lumbia Museum but they never seemed to flower the way they do in the wild.

    Raise Alaskan bunchberries from seed or buy them from a garden centre or nursery where they are occasionally availa­ble. Sow the seed in the fall in a pot of peaty soil and leave over the winter. Plants with a vigorous root system raised in a pot succeed best.

    The name “Cornus”, an ancient name for dogwoods, may be derived from “cornu” an old name for horn, because of the very hard wood of some of the tree dogwood species. The species name “unalaschkensis” recalls that the plant was named after Unalaska Island in the Aleutian Islands.

    Saskatoon Berries. By Walter Siegmund (talk)Own work, CC BY-SA 3.0, Link

    Northern North America is not known as a source of important of fruit crops. Most of our familiar fruits such as ap­ples, plums, and cherries originated elsewhere. Several of our native species, such as coas­tal strawberry (Fragaria chiloensis) have been used in breeding programs. However, Saskatoon (also Saskatoon serviceberry), a showy shrub of the Rose Family (Rosaceae), provides wild fruit and is now grown as a commercial crop.

    Saskatoon grows as a medium shrub to small many-stemmed tree reaching to 7 m (23’) high. The smooth stems are reddish brown to dark grey, and young twigs often silky. The 2.5 – 3.0 cm (1-1.2″) long leaves have an oval outline, but may be slightly pointed at the tip and heart-shaped at the base. Small teeth line part, or all the leaf’s mar­gin. Young leaves are bright green but turn bluish green with age.

    Bright white flowers occur in leafy clusters toward the ends of the branches. Somewhat hairy sepals form a base for the 1-2 cm (0.4-0.8”) long strap-shaped petals. About 20 stamens choke the throat of each flower, where they surround four to five styles.

    The ovary of Saskatoon, like that of the apple or pear, is placed in an inferior position. This means that the sepals and the petals arise from the top of the ovary rather than below it, as is the case in a su­perior ovary.

    The fruit is about 0.5 to 1.0 cm (0.2-0.4”) across, and globe shaped. Its colour ranges from purple to nearly black, often covered by a greyish blue bloom. Good quality fruit is juicy and sweet, however on the coast some of the berries dry out quickly becoming mealy or crunchy with little flavour.

    Saskatoons thrive throughout British Columbia. The continental range extends along the coast from Alaska to California, eastward to New Mexico and north through the plains and prairies into Canada’s Northwest Territories. This shrub favours open to lightly shaded sites such as thickets, fence rows, clearings and edges of woods. A well-drained soil is essential.

    Saskatoons were and are widely picked by First Nations. The Nlaka’pamux (formerly the Thompson) people recognized several types of bushes. Some types were gathered and dried for winter use. Other types were cooked to a jam-like form before being dried. Ed­ible roots of other plants were sometimes soaked in Saskatoon juice to make them more flavourful and sweeter. Dried and rehydrated berries were added to dried vegetables and cooked into soups and puddings.

    Many parts of the Saskatoon plant were used. A drink was made from the bark for stomach problems. Bark and twigs were turned into a medicine for recovery after childbirth and, in combination with other plants, to make a contraceptive. The tough hard wood made excellent arrows. Other uses included digging sticks, spear shafts and handles for tools. Saskatoon sticks were used to spread out cleaned salmon for drying, and the branches to construct shelters.

    Today many British Columbians eat fresh berries off the bush or bake them in tasty pies. You can buy Saskatoon bushes specially bred for the home gar­den. These varieties produce bigger and sweeter fruit than most wild plants. In the prairies Saskatoon plantations yield the raw material for a regional specialty, Saskatoon wine.

    Growing Saskatoons is an easy mat­ter if you have a sunny well-drained site. In the late winter or early spring, buy a bush from the garden centre or order it through the mail. Plant the sapling in a moderately rich, but not heavily-fertilized, soil and mulch around the base. You may have to water during the first year to help the young plant settle in. Saskatoon shrubs can be used in many parts of the garden; the spring flowers are stunning and the bright yellow to red fall leaves provide a cheerful accent. Plants can be grown from seed and dug up as self-sown seedlings too.

    The origin of the name Amelanchier remains unclear. The species name “al­nifolia” means alder-leaved.

    Saskatoon is an outstanding native shrub widely adapted to B.C.’s varying climates. Not only does it yield tasty fruit, but it serves well as a showy gar­den subject. To see Saskatoon berries visit the Native Plant Garden of the Royal British Columbia Museum, Vic­toria, B.C.


    Oemleria cerasiformis

    Spring arrives early in south­western British Columbia, and many plants waste no time producing flowers. June or Indian Plum, known botanically as Oemleria cerasiformis or not long ago as Osmaron­ia cerasiformis, is one of the  earliest of all shrubs to bloom.

    June Plum (also called Oso berry) is a deciduous shrub in the Rose Family (Rosaceae), which grows from 2-5 m (6.5-16.5’) tall. Stems and old branches are grey, but young branches appear dark wine red. The branches form a graceful up­swept pattern. Thin, bright green leaves unfold as early as February. Tapered and oblong, they are usually widest above the mid-point. The leaf margin is smooth-edged and the lower surface paler than the upper. Leaves alternate along the branch, often standing erect when young. Crushed leaves smell like cucumber or watermelon rind.

    Clusters of flowers dangle from the branch tips as the first leaves appear. A fully open flower cluster may reach 10 cm (4″) long and have six to 12 blooms. Each greenish-white  blossom is about 1-1.5 cm (1/4-1/2″) across. Some people describe the flowers as almond-scented, whereas others call them bad smelling! In any case, once you have smelled them, their scent will be forever recognizable.

    Five small greenish sepals and five greenish-white rounded petals arise from the edges of a cup-shaped structure, called a hypan­thium. The hypanthium is formed from the swollen end of the stalklet bearing the flower. Stamens or pis­tils reside in the cup of the flower with male and female flowers on separate plants. In the male flower, 15 stamens form three rows at the edge and just inside the cup. Five pistils crowd together in the bottom of the female flower cup.

    Male plants, perhaps surprisingly, produce the most abundant and showiest flowers. Having male and female flowers on separ­ate bushes reduces the chances of in-breeding. But a great mystery surrounds the question of pollination. At flowering time there are few if any, bees out. Possibly na­tive beetles do the honour, but even after many hours of observation, the responsible party has yet to been seen for sure.

    Small fruits appear in spring. At first these are a pleasant peach colour but soon darken to dark blue or nearly black. Like their distant relatives, the true plums, the fruits are covered in a greyish bloom. A prominent groove marks one side of the fruit. Birds especi­ally Cedar Waxwings gobble up ripe fruit and disperse the seed.

    The distribution of June plum, hugs the southwest coast of British Columbia, on south Vancouver Island north to about Campbell River,  and on the mainland as far as Yale and Squamish. Moist thickets, open woods and stream banks are its favourite haunts. June plums occur along the Pacific Coast, west of the Cascade Mountains as far south as northern California.

    Where the climate permits, June plum makes a fine early spring shrub for the wild or woodland gar­den. It thrives in the Native Plant Garden of the Royal British Colum­bia Museum where it requires little maintenance. The coloured fruits also draw much attention in early summer.

    For flower and fruit display you will need one male and one female plant. This shrub is raised from suckers, twig cuttings or seeds. Seeds need a long, cold moist spell followed by a warm interval to germinate, so best plant them in the summer when fruit ripens and leave until the following spring. You may often find seedlings in fence lines and shrubs where birds perch and pass seed.

    Generally, the fruit has a bitter choking taste, though I find fully ripe fruit tasty.  Ne­vertheless, First Nations people around the southern Strait of Georgia and Puget Sound ate small quantities of fresh or dried “plums”. The fruit is not poisonous, although at the Royal BC Museum we get  calls from concerned parents whose children have tried it. First Nations of the Saanich Pe­ninsula still boil Indian plum bark (sticks) in water and drink the li­quid for diarrhea. Bark is also used in a complex mixture to treat several serious ailments.

    Oemlaria got its name from an obscure individual called “Oemler”. The species name cera­siformis refers to the cherry-shaped appearance of the fruits.

    See June plum in the Native Plant Garden at the Royal BC Museum at any time of the year. It is at its best in the warming days of late February and March when the first flowers open to greet the sun.

    Hanging flower clusters of bigleaf maple. Note the protruding stamens. Photo by Dr. Richard Hebda.

    We have long recognized the vital role of shade trees in creating a pleasant environment around our homes. Most shade tree species and varieties hail from distant regions and lands. British Columbia is home to one of the noblest, but for some reason little-used shade trees, bigleaf maple.

    Bigleaf, broadleaf, common or Oregon maple grows as a tall spreading tree to 30 m (100′) high, casting filtered shade beneath. In undamaged trees, the widely spreading root system supports a short trunk 60-150 cm (2-5′) across, from which reach out great limbs. However many trees have been cut, and hence grow as groups of tall greyish sapling stems. Old branches are bedecked and festooned with colourful mosses, leafy and crusty lichens. Young twigs are coloured an attractive medium green. Fat green buds end the branches during the winter.

    Leaves of bigleaf maple are the largest of any tree in British Columbia. Their form is typical for maples; three to five sharply-tipped lobes with deep indentations between them. Spring foliage emerges soft yellow green in the sun’s light and soon expands to full size, some leaves more than 30 cm (12″) across. In fall the foliage mantles each tree in a rich yellow-orange cloak, before the leaves fall to earth to be crunched underfoot.

    The 10-15 cm (4-6″) long flower clusters rival any in the genus of maples. They burst forth in early spring revealing often 50 or more small greenish yellow fragrant blooms. Male and female flowers are separate, but occur in the same cluster. Each flower consists of petal-like sepals, and five petals surrounding either a group of long protruding spindly stamens or a two-parted ovary with two stigmas. The clusters magnetically attract pollinating flies until each tree hums softly like a giant machine. The large fruits have the typical form of maple keys consisting of a wing and body. The spiny hairs, which cover the surface of the body, will penetrate and irritate the skin.

    In British Columbia the maple’s natural range includes most of Vancouver Island and the adjacent mainland coast, extending well up major valleys. Bigleaf maple is reported as far north as Alaska, but the main distribution extends from BC mostly west of the Cascade Mountains south to California with an outlying population in Idaho. Bigleaf maple thrives in rich moist soils especially along rivers, streams and floodplains. Curiously you will also find it on moist rocky slopes often rooted in the rubble at the foot of cliffs. The tree grows well in disturbed settings along roads and fence rows.

    Although some authors consider bigleaf maple of little horticultural value, it makes an outstanding shade tree. The airy canopy produces light, rather than oppressive shade. Once the leaves fall, weak but welcome winter sunlight can penetrate into the home. Because of its size, this maple may not suit refined urban gardens, but it cannot be beat as a huge specimen tree for a large yard, park or street planting. You can easily raise maple trees from seeds planted in ordinary soil. Often, hundreds of seedlings struggle to survive under majestic parent trees. These seedlings transplant easily in the moist coastal winter and spring. You may have a problem growing a traditional flower gar­den below the thirsty tree. However, native species such as salal (Gaultheria shallon), Oregon Grape (Mahonia spp.) and sword fern (Polystichum munitum) thrive beneath its umbrella.

    Bigleaf maple wood found many uses among British Columbia’s coastal First Nations. From it they made dishes, spoons, rattles, bark shredders, axe handles and numerous other tools. The wood is perhaps best known for the carving of beautiful spindle whorls and canoe paddles. Many aboriginal peoples valued the wood as a fuel, for it burns hot and clean. Bigleaf maple is an excellent fuel tree today too, because it can be cut to harvest the firewood and re-sprout fresh new suckers for future wood production. Well-managed root systems and stumps  yield firewood for many decades. Aboriginal people also used the bark to weave ropes and baskets. The large leaves were spread over and under food in steam pits and picking baskets.

    Incidentally people have tried to make syrup from spring sap but the sugar concentrations are mostly too low and the day-night temperature changes too slight for a good flow.

    The scientific name Acer derives from the classic Latin name for maple. The species name “macrophyllum” celebrates the tree’s most obvious feature, the big (macro) leaves (phyllum). This handsome arboreal giant and other maples were once happily in the Maple family (Aceraceae). Now through the wonders of DNA analysis they have been added to the Horse-chestnut family Sapindaceae.

    Looking for a shade tree or an excellent permanent firewood source, try our native bigleaf maple. This under-appreciated native species deserves to be more widely grown. For more information on native species please visit our Native Plant Garden, of the Royal British Columbia Museum in Victoria.




    The introduction of potentially invasive species remains a global threat to biodiversity and ecosystem services. The spatial distribution of introduced species can provide insight into present and historical vectors of invasion. Here, we aim to investigate the influence of environmental, demographic and vector variables on the spatial distribution of non-indigenous species (NIS) in coastal marine ecosystems.


    Coastal British Columbia, Canada.


    We used subtidal settlement plates to sample NIS richness at 81 sites. Spatial patterns for seventeen environmental, population, and vector variables were created using a Geographic Information System (GIS). We used multiple regression with model selection and spatial autocorrelation to define a statistical model that best explained the spatial distribution of NIS.


    Four variables, salinity, human population density, port arrivals and marina propulsiveness (probability of boater travel from home marina), best explained the observed spatial distribution of subtidal NIS. Aquaculture, an original global introduction pathway, did not significantly explain the contemporary distribution of NIS. Results suggest that recreational boating is the most probable pathway of fouling NIS spread in this region, driving their current distribution. Spatial autocorrelation was significant for environmental, demographic, and aquaculture variables. However, marina propulsiveness and attractiveness were not autocorrelated, suggesting that boater behaviour varies on a finer scale.

    Main conclusions

    A simple model using a combination of vector, demographic, and environmental characteristics can explain 43.6% of the variation in the spatial distribution of NIS. Our study provides further evidence that recreational boating is a significant pathway for the contemporary spread of NIS in marine environments. With projected increases in human population, we expect a continued rise in introduction rates and spread in this region and elsewhere in the world.

    Here, we report the first records of the non-native amphipod Caprella mutica along the coast of British Columbia, Canada. Between 2006 and 2009, we surveyed marine fouling communities across 81 subtidal sites, and sampled hulls and sea-chests from 18 domestically operated commercial vessels. Caprella mutica was present at 33% of the sites and on 22% of the vessels, sometimes at remarkably high densities (>10,000 individuals m-2). Our findings confirm an extensive distribution of C. mutica along the coast of the northeast Pacific, and offer additional evidence in support of hull fouling as an important vector for secondary spread. Key words: caprellid, introduced, northeast Pacific, biofouling, sea-chest, vector, museum records

    Marine fouling communities on artificial structures are invasion hotspots for non-indigenous species (NIS). Yet, little is known about NIS in fouling communities of British Columbia (BC), Canada. To determine NIS identity and richness in BC fouling communities, we deployed settlement plates at 108 sites along the coast of BC between 2006 and 2012. Of the 295 invertebrate taxa identified to species, 20 were NIS while an additional 14 were cryptogenic, including several global invaders. This study documents the range expansion of tunicates Botrylloides violaceus Oka, 1927 and Botryllus schlosseri (Pallas, 1766), including the first known records on Haida Gwaii. NIS were detected within each of the six distinct geographic regions with the southern, more populated regions of BC (Straits of Georgia and Juan De Fuca) having the highest NIS richness and frequency of occurrence compared to the less populated northern regions. This study provides a contemporary baseline of invertebrate NIS identity and richness in fouling communities that will allow comparisons through time and a means to focus research and prioritize management efforts.

    Sedum spathulifolium

    British Columbia is full of rocks, and rocks are not hospitable places to make a living. One group of plants, the stonecrops (Sedum spp.), have adapted super­bly to this often harsh setting. Broad-leaved (also broadleaf)  stonecrop (Sedum spathulifolium) is an exceptionally attractive and abundant stonecrop reveling in the stony outcrops on the coast of our province.

    Broad-leaved stonecrop of the Stonecrop Family (Crassulaceae), forms low, spreading mats in patches of densely-packed rosettes of flattened leaves. These leaf rosettes arise along a creeping stem called a stolon. Clusters of fibrous roots from the stem cling tenaciously to rocks and shallow soil spreading from crevice to crevice. About 15 leaves form the rosettes which typically re­ach 2-4 cm (0.8-1.6″) across. The fleshy, greyish-green leaf blades sit almost directly on the stem.  Each leaf broadens out wider than the base to a broad tip, hence the common name. Like many plants which survive in harsh dry places, this herb stores water in its thick leaves.

    Brilliant yellow flower heads adorn stiff stalks which stand about 10-15 cm (4-6″) tall. Small five-petalled star-like flowers crowd the flower head. The narrow pointed petals sur­round a cluster of 10 yellow stamens 5 pistils.  In British Columbia, the flowers appear mostly from May to July.

    Broad-leaved stonecrop grows abun­dantly on coastal cliffs and dry sites on Vancouver Island and adjacent Gulf Islands but less frequently on the nearby mainland. The range ex­tends southward as far as California. Look for stonecrop along the shore and even well up mountain slopes in dry forest openings.

    This stonecrop excels as a garden plant for dry sites. Simply plant a small piece of rooted stem in a little bit of soil. Try it in a rock garden, on a stone wall or next to a stone or gra­vel path. Even tuck it into a roadside rock face. Can you image what our rocky roadsides might look like covered in brilliant yellow? Once this plant takes hold, it will spread in a most attractive manner plugging cracks between rocks and blanketing rough spots. This species tolerates some shade too, although its form becomes gen­erally looser. Stonecrop needs little attention once established; remove dead stems after flowering if you wish, and keep grasses from rooting in the mat. As the patch expands you will be rewarded with plenty of offsets for new plantings. I have watched  a small piece double in size after a month and quadruple after a season. Broad-leaved stonecrop is one of the easier native plants to get because it is occasion­ally available through garden centres. Indeed, several forms, in­cluding some with reddish or pur­plish leaves, others with a bluish hue, are being sold. A grey-white variety called ‘Cape Blanco’ seems to be widely available. You could create a rock garden of varying hue by planting several different colour forms. Broad-leaved stonecrop is hardy to zones 5-6 in Canada.
    First Peoples put stonecrop to some interesting uses. Nlaka’pamux (previously Thompson) People of the Fraser River Canyon boiled the whole plant and used the liquid to soothe cross babies and relieve constipation. Stonecrops, in general, were used to make poul­tices for treating piles.

    The scientific name Sedum appar­ently was used for stonecrops in an­cient times, possibly derived from the Latin “sedeo” which means “I sit” as indeed it does on its favoured stony substrates. Come and see broadleaf stonecrop sitting around on the rocks in the Native Plant Garden of the Royal British Co­lumbia Museum in Victoria.

    Mahonia aquifolium

    British Columbia is home to a diverse collection of gorgeous native shrubs. Many of them produce edible wild fruit too. Few are as versatile and adaptable to the home garden as the Oregon-grapes (Mahonia spp.) and of these Tall Oregon-grape (Mahonia aquifolium) has the highest profile.

    Tall Oregon-grape forms handsome shrubby clumps of few to many upright greyish canes. Wild clumps normally grow half to one and a half metres (20-60″) tall, but straggly individuals can reach 2.5 m (100″). The inside of the stems and roots is coloured brightly yellow. Shiny, com­pound evergreen leaves, with 5-9 leaflets crowd toward the ends of stems. Spiny teeth line leaflet edges giving rise to the species name “aquifolium” which is a classical name for holly (Ilex  spp). Hollyleaved barberry is another name for the plant and as is the case with the holly the leaves can be painful. In the summer, leaves shine lustrous green, but in the winter they turn an attractive bronze or even red. Delicate new spring growth emerges reddish too.

    On the coast many-flowered clusters of brilliant yel­low blossoms appear as early as late February and persist into April. Often several clusters throng the end of a stem creating a colourful display. In the blooms of this plant, the petals and sepals are both coloured so that each delicately scented flower has three whorls of three petal-like segments. Glands at the base of the seg­ments produce clear drops of nectar. Inside a ring of seven yellowish stamens, each with peculiar projecting “ears”, squats a greenish pistil. Grape-like bunches of small blue berries replace the flowers in late spring and sum­mer. The stunning display of abundant fruits is so appealing that you might be tempted to stuff them into your mouth. Avoid that temptation because the berries are mouth-pucker sour and contain large seeds.

    In British Columbia this shrub occurs from Prince George southward in the inte­rior and to the north end of Vancouver Island on the coast. The range extends southward into Oregon and eastward to Idaho. The natural habitat includes open wood­land, edges of meadows and, in the in­terior, sagebrush covered hills.

    Tall Oregon-grape was introduced to European gardens in the early 1800s. Generally it is a co-operative horticultural shrub especially for partly-shaded to open well-drained sites. Once planted it may need oc­casional pruning immediately after flowering to keep a neat form. Cold, drying winter winds kill exposed foliage. Try tall Oregon-grape in a shrub border, hedge, or naturalized thickets along with Nootka rose (Rosa nutkana) and snowberries (Sym­phoricarpos spp.). Landscapers use it widely around institutional buildings on south Vancouver Island. A dense hedge of it may keep out nosy intruders.

    Tall Oregon-grape plants are easi­ly obtained from garden centres and nurseries on the west coast. They can be grown from seed too. Sow ripe seed in the fall and transplant young seed­lings the following fall into nursery beds. At the Native Plant Garden of the Royal British Columbia Museum tall Oregon-grape spreads widely by seed into adjacent herbaceous beds. Thickets spread outward underground so prepare to keep them in check.

    First Peoples knew tall Oregon-grape well. They ate the fresh berries and, on south Vancouver Island, used them as an antidote to shellfish poisoning. Nlaka’pamux (previously Thompson) People of the Fraser River Canyon boiled the outer bark of the roots to make a bright yellow dye for baskets. Liquid from the bark of boiled woody stems helped treat red itchy eyes.

    The blue berries make an excellent wild jelly. Use lots of sugar to moderate the tartness, and screen out the large and bitter seeds.

    Our Oregon-grapes have been known botanically by two names: Mahonia and Berberis. Mahonia, honours an 18-19th century American horticul­turalist Bernard M’Mahon. The name Berberis (barberry in English) originates in a similar Arabic name for barberry fruit.

    Tall Oregon-grape is a wonderful coastal landscape shrub. It is attractive all year round and produces edible ber­ries. Look for it and its berries in the wild and come and see masses of it at the Native Plant Garden of the Museum in Victoria.

    There isn’t a month of the year where European Wall Lizards are completely torpid here on Vancouver Island. We are nearing the solstice, and lizards are still out and about.

    AI went out with my wife and daughter to Crumsby’s this weekend, and later, we had plans to do some shopping – and groceries – the usual weekend activities.

    But the weather was nice – 7 degrees Celsius and sunny – so I suggested we divert to the Moss Rocks area for a few minutes and see if we could find a European Wall Lizard. My wife now accepts such requests as normal – we may be talking about christmas shopping and trying to entertain our daughter, but she knows I am looking for lizards if it is sunny. At least lizards in a cup, tub, or zip-lock bag don’t smell as bad as some of the road-kill we have collected.

    I saw – or more accurately heard – the first lizard just as I stepped out of the car. Within seconds I had evidence of lizards active in December. They were high up on the bedrock wall along May Street. A patient wait of a few more minutes was rewarded by sight of three lizards which crawled out of a cold crevice, and lined up to absorb as much heat as possible from the sun.

    BFarther along the street was a concrete wall covered in roots – an easy place to ambush a lizard. There were at least 8 lizards on that small concrete wall – I caught these three in two minutes. They now are preserved a cataloged as 2127 in the Royal BC Museum’s herpetology collection as evidence of the winter activity of an invasive lizard.

    Interesting tidbit of information was that the lizards were warm to the touch – they must find really effective basking sites to warm themselves that much above the ambient air temperature. The rocks themselves were not that warm.

    We report the recent discovery of Oxypolis occidentalis, a species that is new to both British Columbia and Canada, disjunct on the Queen Charlotte Islands.

    Aim  Late Pleistocene ice sheets are thought to have covered most of western Canada, including all of British Columbia (BC). We examine patterns of genetic variation in an Arctic–alpine plant to evaluate the possibility of full glacial refugia within the area covered by the Cordilleran ice sheet (CIS) and to uncover post-glacial migration routes.

    Location  Western North America.

    Methods  We sampled 1030 individuals of the Arctic–alpine plant Oxyria digyna from 117 populations distributed over much of its range in western and northern North America. DNA haplotypes were identified using restriction site analysis of two chloroplast DNA intergene spacer regions, psbA-trnH and trnT-L. We examined the geographical distribution of haplotype diversity in relation to latitude, and also compared various indices of diversity in putatively glaciated and unglaciated regions. Patterns of migration were inferred using nested clade analysis.

    Results  We detected a total of 20 haplotypes. High haplotype diversity was found in Beringia, in unglaciated western USA, and in northern BC at 57–59° N, well within the accepted limits of the CIS. Ancestral haplotypes were also centred in northern BC.

    Main conclusions  High genetic diversity of Oxyria digyna is expected in unglaciated regions, but unexpected in northern BC if British Columbia was entirely covered by ice during the late Pleistocene. Our observations suggest the presence of unglaciated areas providing late Pleistocene refugia in northern BC. Such refugia would have important implications for the origins and migrations of many plant and animal species in north-western North America.

    The ranges of arctic-alpine species have shifted extensively with Pleistocene climate changes and glaciations. Using sequence data from the trnH-psbA and trnT-trnL chloroplast DNA spacer regions, we investigated the phylogeography of the widespread, ancient (>3 million years) arctic-alpine plant Oxyria digyna (Polygonaceae). We identified 45 haplotypes and six highly divergent major lineages; estimated ages of these lineages (time to most recent common ancestor, T(MRCA)) ranged from ∼0.5 to 2.5 million years. One lineage is widespread in the arctic, a second is restricted to the southern Rocky Mountains of the western United States, and a third was found only in the Himalayan and Altai regions of Asia. Three other lineages are widespread in western North America, where they overlap extensively. The high genetic diversity and the presence of divergent major cpDNA lineages within Oxyria digyna reflect its age and suggest that it was widespread during much of its history. The distributions of individual lineages indicate repeated spread of Oxyria digyna through North America over multiple glacial cycles. During the Last Glacial Maximum it persisted in multiple refugia in western North America, including Beringia, south of the continental ice, and within the northern limits of the Cordilleran ice sheet. Our data contribute to a growing body of evidence that arctic-alpine species have migrated from different source regions over multiple glacial cycles and that cryptic refugia contributed to persistence through the Last Glacial Maximum.

    Many plant species comprising the present-day Arctic flora are thought to have originated in the high mountains of North America and Eurasia, migrated northwards as global temperatures fell during the late Tertiary period, and thereafter attained a circumarctic distribution. However, supporting evidence for this hypothesis that provides a temporal framework for the origin, spread and initial attainment of a circumarctic distribution by an arctic plant is currently lacking. Here we examined the origin and initial formation of a circumarctic distribution of the arctic mountain sorrel (Oxyria digyna) by conducting a phylogeographic analysis of plastid and nuclear gene DNA variation. We provide evidence for an origin of this species in the Qinghai-Tibet Plateau of southwestern China, followed by migration into Russia c. 11 million yr ago (Ma), eastwards into North America by c. 4 Ma, and westwards into Western Europe by c. 1.96 Ma. Thereafter, the species attained a circumarctic distribution by colonizing Greenland from both sides of the Atlantic Ocean. Following the arrival of the species in North America and Europe, population sizes appear to have increased and then stabilized there over the last 1 million yr. However, in Greenland a marked reduction followed by an expansion in population size is indicated to have occurred during the Pleistocene.

    We investigated genetic variation in Bistorta vivipara, a widespread Northern Hemisphere tundra species, to infer patterns of migration and where it may have survived during the Last Glacial Maximum (LGM).


    Samples came primarily from western North America, with a few from the Arctic and Eurasia.


    We sequenced two chloroplast DNA spacer regions, trnH–psbA and trnSG, in individuals from 199 populations and mapped haplotype distributions and their relationships using a haplotype network. We calculated genetic and molecular diversity statistics for the seven geographical regions from which we obtained samples.


    Fifteen haplotypes were detected, with very little divergence among them. The haplotypes are separated into two main groups by the presence or absence of a 22 bp tandem duplication. Four haplotypes are common, widespread and with substantial range overlap; 11 are rare and mostly unique to one region. Two rare haplotypes were found only in British Columbia (BC). Western North America and Asia have the highest levels of genetic and molecular diversity. Northern and southern BC have different haplotype complements.

    Main conclusions

    Bistorta vivipara has relatively low genetic diversity, with much less genetic structure than we expected for such a widespread species. We expected significant geographical structure due to the combined effects of genetic drift and geographical isolation. The asexual reproductive mode of B. vivipara may facilitate relatively rapid population establishment and spread compared with sexual reproduction by seed. Bistorta vivipara probably originated in Asia and spread to North America and Europe prior to the LGM. In western North America it spread to its modern distribution from Beringia and the western USA following the LGM. Populations in northern and southern BC may have different histories, possibly related to the timing and extent of glaciation. The occurrence of two unique haplotypes within BC suggests that some individuals may have survived in full glacial refugia within BC.

    Many plants, especially at high latitudes, have both widespread and highly discontinuous geographical distributions. To increase understanding of how such patterns originate, we examine genetic patterns in the arctic–alpine plant Sibbaldia procumbens. We evaluate the contributions of refugia and the role of long-distance dispersal in shaping the current range of this species.


    Northern Hemisphere, especially North America.


    We sampled Sibbaldia from 176 localities, including 168 for S. pro-cumbens. We analysed sequence variation in three plastid DNA non-coding regions (the atpI–atpH and trnL–trnF intergenic spacers and the trnL intron), performed Bayesian phylogenetic analyses and statistical parsimony analyses on the combined sequences, and analysed the geographical patterns of haplotype distribution and genetic diversity using data from all populations.


    Sibbaldia procumbens probably originated in the mountains of South and East Asia. We identified highly distinct clades in Europe and North America, which overlapped on oceanic islands of the North Atlantic indicating long-distance dispersal capability. The North American clade included two lineages, one in California and the other widely distributed across the continent and North Atlantic. Haplotype diversity in the latter lineage was markedly higher to the south, suggesting mid–late Pleistocene southward displacement of North American populations with subsequent migration northwards into previously glaciated regions. In Europe, disjunct geographical regions generally harboured distinct haplotypes.

    Main conclusions

    Multiple Pleistocene refugia for S. procumbens occurred in both North America and Europe. North American refugia existed in California and in the southern Rocky Mountains, but in contrast with most widespread arctic–alpine species we found no evidence for a Beringian refugium. Cryptic refugia may have existed within the Cordilleran Ice Sheet. Episodes of range expansion and contraction and long-distance dispersal have all contributed to the genetic structure and widespread but fragmented distribution of this species.

    PREMISE OF THE STUDY: Many arctic-alpine species have vast geographic ranges, but these may encompass substantial gaps whose origins are poorly understood. Here we address the phylogeographic history of Silene acaulis, a perennial cushion plant with a circumpolar distribution except for a large gap in Siberia.

    METHODS: We assessed genetic variation in a range-wide sample of 103 populations using plastid DNA (pDNA) sequences and AFLPs (amplified fragment length polymorphisms). We constructed a haplotype network and performed Bayesian phylogenetic analyses based on plastid sequences. We visualized AFLP patterns using principal coordinate analysis, identified genetic groups using the program structure, and estimated genetic diversity and rarity indices by geographic region.

    KEY RESULTS: The history of the main pDNA lineages was estimated to span several glaciations. AFLP data revealed a distinct division between Beringia/North America and Europe/East Greenland. These two regions shared only one of 17 pDNA haplotypes. Populations on opposite sides of the Siberian range gap (Ural Mountains and Chukotka) were genetically distinct and appear to have resulted from postglacial leading-edge colonizations. We inferred two refugia in North America (Beringia and the southern Rocky Mountains) and two in Europe (central-southern Europe and northern Europe/East Greenland). Patterns in the East Atlantic region suggested transoceanic long-distance dispersal events.

    CONCLUSIONS: Silene acaulis has a highly dynamic history characterized by vicariance, regional extinction, and recolonization, with persistence in at least four refugia. Long-distance dispersal explains patterns across the Atlantic Ocean, but we found no evidence of dispersal across the Siberian range gap.

    We used PCA of morphological characters to confirm the presence of an undescribed Calamagrostis species in Washington and Oregon that has historically been attributed to Calamagrostis vaseyi. We propose to name this grass Calamagrostis tacomensis. It is most similar to C. foliosa although it has often been confused with C. purpurascens and C. sesquiflora all of which have similar lemma awn characteristics (i.e., the awn relatively long, exserted, and bent). Calamagrostis tacomensis has been collected at high elevations (490–2170 m) in the Washington Cascades, the Olympic Peninsula and the Steens Mountains of Oregon. The name C. vaseyi has been misapplied to our new species. The description of C. vaseyi is similar to C. rubescens. We have studied the specimen that has been attributed to be the type of C. vaseyi and it is C. purpurascens. We lectotypify C. vaseyi.

    The taxonomically difficult and ecologically and phytogeographically important genus, Calamagrostis, was examined for British Columbia (BC). Morphological characters were analyzed by Principal Components Analysis (PCA) to characterize taxa and to aid in the development of a new key. Eight native species (Calamagrostis canadensis, C. lapponica, C. montanensis, C. nutkaensis, C. purpurascens, C. rubescens, C. sesquiflora, and C. stricta) are confirmed to occur in British Columbia, of which C. montanensis, C. nutkaensis, C. purpurascens, C. rubescens, and C. sesquiflora are reliably distinguishable. Comparison of species distribution to regional climatic and vegetation history suggests that Calamagrostis nutkaensis and C. sesquiflora likely survived in coastal refugia during late Wisconsin glaciations. Calamagrostis purpurascens likely persisted beyond the glacial limits or within nunataks and then spread into previously glaciated sites. Two interior continental species, C. montanensis and C. rubescens, probably spread north and west from the unglaciated zone south of the Cordilleran and Laurentide ice sheets. Calamagrostis lapponica likely persisted north of the ice sheets, and then spread southward into high-elevation sites in northern and eastern BC. Calamagrostis canadensis and C. stricta probably survived south and north of the ice sheets, and then spread into the previously glaciated terrain.


    Between 2002 and 2011, we collected vascular plants from alpine areas of northern British Columbia (B.C.). We have found one species that has not previously been collected in the province: Phippsia algida. Collections of an additional three species represent significant range extensions of species already known to occur in the province: Aphragmus eschscholtzianus, Papaver alboroseum, and Montia bostockii. Our collections of Delphinium brachycentrum initially appeared to be the first records for the province; however, examination of herbarium specimens at the Royal British Columbia Museum herbarium indicated that this species had been collected prior to our field work but had been misidentified. We indicate the distribution of this species in B.C. for the first time, and we present a corrected distribution map for Tephroseris yukonensis that includes our
    own collections.

    The distribution of northern British Columbia alpine plants is poorly documented. To improve our understanding of the flora of this vast, remote region, we collected more than 11 000 specimens from 65 mountains during 2002–2011. Most of these locations had not been visited by botanists. Of the more than 400 species we have collected, two are new to the province, others represent significant range extensions. Twelve species share elements of a disjunct distribution that has apparently not been previously recognized and consists of three regions: (1) northwestern North America; (2) Beartooth Plateau; and (3) northern Colorado. These 12 species appear to be absent from the extensive areas of suitable habitat that occur in the intervening areas. The most reasonable explanation for this pattern is that these species, adapted to arctic–alpine tundra conditions, migrated throughout western North America during the Pleistocene, a time when suitable habitat was much more widespread than now, and subsequently went extinct in many areas as the climate warmed during the Holocene.

    Polystichum munitum

    Western Sword Fern (<em>Polystichum munitum</em>) growing in the Columbia River gorge, June 24 2006. <a href="">Jami Dwyer.</a>

    A young clump of sword fern.

    British Columbia’s moist and mild coastal climate provides ideal conditions for ferns to thrive, so much so that several fern species are obvious and characteristic features of the conifer forest floor. Most abundant of all these ferns is the stately and lush sword fern of the Wood Fern Family (Dryopteridaceae).

    Sword ferns grow into a large perennial clump of leaves spreading out from a massive crown. This crown consists of a woody mass of rhizomes (root-stems) buried in reddish brown scales and dead leaf bases. Roots explore the soil outward from the rhizome. In a mature well-established clump the crown may stretch half a meter (20”) or more in diameter.

    Dark evergreen fronds stand stiffly from the crown. Fronds reach as tall as 1.5 metres (60”) and up to 25 cm (10″) wide. The lower third of the frond consists of a den­sely scaly brown stalk, called a stipe by botanists. The upper two-thirds of the frond have numerous narrow, pointed and toothed leaflets. Near the tip of the frond the leaflets become progressively shorter. Young unfolding leaves are at first curled like a shepherd’s crook or crozier, then gradually un­furl and expand.

    Ferns are not flowering plants; they reproduce by spores which are microscopic pollen-grain like bits of plant tissue. Spores form inside tiny thin-walled sacs called sporangia. The sporangia of sword fern cluster in brown dot-like structures called “sori” (singular “soros”), which line the back of each leaflet of the frond. These many (= “polys” in Greek) lines (= “stichos” in Greek) of sori give rise to the scientific name Polystichum. The species name munitum (“armed”) derives from the numerous pointed teeth along the leaflets.

    Sporangia split open and the spores drift to the ground where they germinate only if it’s moist. The spores grow into small delicate mini-plants called gametophytes with only one set of chromosomes, half of the double set of the much larger and robust parent. Male and female struc­tures develop on the gametophytes and male sperm swim to fertilize the female egg. Once fertilized, the egg develops into a proper leafy fern plant.

    In British Columbia sword fern is dominantly a coastal species, occurring more than two-thirds of the way to the Yukon border. The range extends across extreme southern B.C. and adjacent Washington and Idaho in moist climates in the southeast part of the province. The North American range extends along the coast from Alaska almost to the Mexican border. Generally sword fern thrives in the shaded humus of the damp to moist conifer forest floor. In very wet forests you may see it perched on a shady rock face. Sword fern forms a distinctive association with western redcedar (Thuja plicata) on nutrient rich seepage sites. Fern clumps completely cover the forest floor, in a manner some­what reminiscent of a lush tropical jungle. A stiffer narrow-leaved species of sword fern, called imbricate sword fern (Polvstichun im­bricans) grows among boulders and in rock crevices in dry, usually open settings.

    Aboriginal British Colum­bians used sword fern for various purposes. In spring rhizomes were dug, cleaned and roasted in open fires or earth pits. Cooked rhizomes were then peeled and eaten usually with grease or salmon eggs. The fronds were used to line pits for cooking root foods and to line boxes and baskets. Fern fronds also provided a decorative motif for basket designs.

    Sword fern is among the easiest ferns to grow in the garden. Since this fern is so ubiquitous in coastal lowland sites, many suburban building lots come with their own supply. If possible it’s best to leave the clump where it sits, making sure there is shade. However the plants transplant readily and many can be easily rescued from development projects. Sword fern is one of the more widely available of our native species. So ask the owner of your local garden centre or nursery to order it in if you cannot get it from a friend or rescue site. Spores spread about a moist and shaded site will yield even more fern plants in a few years.

    For best results, choose a shaded to partly open damp setting. In the Native Plant Garden at the Royal BC Museum we have used it in a mass planting under trees between two buildings where it suits the poorly lit situation much better than a high care lawn. Sword fern is ideal for a woodland garden, providing a lush verdant framework for the garden’s further development. Once established, the only care the fern needs is the removal of unsightly dry fronds in winter.

    Try ferns in your garden: many are well suited for those difficult shaded sites. Ferns also illustrate how less-advanced plants reproduce without flowers. Visit the Native Plant Garden at the museum and see luxuriant clumps of sword fern and other fern species.

    Arbutus menziesii

    The Heather Family (Ericaceae) is well known in Canada for its many shrubby species such as blueberries (Vaccinium spp.), salal (Gaultheria shallon) and Labrador tea (Rhododendron gro­enlandicum; previously Ledum groenlandicum). We in British Columbia are fortunate to have the only tree-sized member of the Heather Family in Canada, the distinctive and handsome arbutus (Arbutus menziesii) also known as Pacific madrone, madrona and strawberry tree.

    Arbutus grows into a multi-stemmed shrub or tree with crooked trunks sometimes twisting their way up to 35 m (approxi­mately 120′) tall. The smooth reddish bark stands out from that of all other trees in our province. It flakes off in the late fall, being replaced by young greenish yellow bark from beneath as the trees begin to swell and grow with fall mois­ture.

    Leathery, oval evergreen leaves cluster toward the ends of the branches. Above they are shiny green, but below they are pale. Typical leaves range from 5-15 cm (2-6”) long, Young shoots bear finely toothed leaves whereas those of mature shoots have no teeth.


    Arbutus flowers. Photo by Dr. Ken Marr.

    Like bunches of grapes, great clus­ters of creamy or pinkish white, honey-scented flowers adorn the ends of the branches. Each small flower resem­bles a tiny white bell, pinched in at the mouth. The tips of the petals form five little teeth, a feature common to many flowers of the Heather Family. Within the flower nestle 10 stamens and a sin­gle five-parted pistil.

    Brick-red berries form in the late fall and persist well into winter. Each fruit in the cluster is about a centimeter (0.4″) across and covered by tiny little bumps. Birds, especially grouse, feast on these attractive fruits.

    The geographic range of arbutus hugs the Paci­fic Coast of North America from south­ern British Columbia to California. In our province, arbutus occurs on the southern two-thirds of Vancouver Island, especially the east side, and the adjacent Mainland almost to Knight Inlet. Rocky knolls and cliffs provide the classic hang-out for the species. The tree appears to wrest nu­trients from the bare rock itself. Arbu­tus grows extremely well in open dry Douglas-fir (Pseudotsuga menziesii) woodland and forest, where the soils are deeper. On these sites, trees can re­ach great girth and height at times forming “magical” groves. In Victoria arbutus trees and shrubs appear in boulevards and on roadside banks “inoculated” so to speak, by perching birds

    Once established, arbutus makes a superb, undemanding garden and landscape plant. Evergreen leaves, exquisitely attractive bark, beautiful flowers and brilliant berries are out­standing features. The only draw­backs may be the cleanup of the leaves, particularly in the late summer, and the lack of frost tolerance. There is also a stem canker present in the re­gion which can kill branches.


    Arbutus Berries. Image courtesy of Dr. Richard Hebda.

    The easiest way to have arbutus on your property is to leave and encourage already estab­lished plants. You can raise arbutus with relative ease from seed sown in the fall and covered lightly in a peat-potting soil-sand mixture. If you have a very dry south, or west-facing site, simply spread fruits collected in the fall, and you will be surprised at the rate of successful germination in places where you could never expect to plant a seedling. Arbutus plants lar­ger than 20 cm (8″) tall are almost im­possible to transplant and should ne­ver be dug up. Move only seedlings from waste sites with loose soils in the wettest part of the winter. Be sure to dig up the entire root and keep as much of the soil attached as possible. Occasionally, potted seedlings are available at garden centres and native plant sales.

    Aboriginal peoples put arbutus to assorted uses in technology and me­dicine. Saanich people used the wood for spoons and gambling sticks. The Sechelt made keels and sterns for small boats from the hard wood. Dye from bark was used to color wooden utensils and camas bulbs in cooking pits. On the Saanich Peninsula, leaves and bark yielded medicines for colds, stomach problems, tuberculosis and birth control.

    The dense hard wood is widely used for artistic carving, taking polish very well. It also provides hot slow-burning firewood.

    The scientific name Arbutus is the same name as Romans used for a simi­lar and closely-related tree known as the Strawberry tree (Arbutus unedo) The spe­cies name, menziesii, honours Archi­bald Menzies, Royal Navy botanist and surgeon, who collected many plants in our area in the 1780’s and 1790’s.

    You can see and learn more about arbutus and many other members of the Heather Family at the Native Plant Garden of The Royal British Columbia Museum, 675 Belleville Street, in Victoria, B.C.


    Antennaria rosea

    The search for strong growing, attractive ground-cover plants is a major focus in the low-care gardening of the modern day. Many widely used ground cover plants are not native to British Columbia region and have the bad habitat of being aggressive invaders into our natural environment. Periwinkle (Vinca) and English ivy (Hedera helix) are good examples, and are now the target of removal efforts.

    These non-native garden plants often do not thrive in the drier colder climates of inland British Columbia. Many native species spread widely and establish attractive and tough natural ground covers but are not nearly so invasive grow more vigorously in our inland climates. Rosy pussytoes (Antennaria rosea) is a widespread BC native species of the Aster Family that offers an alternative ground cover choice.

    The pussytoes genus (Antennaria) is not well known to gardeners, yet there are as many as 15 species growing in open and even lightly shaded situations in BC from the hot valley bottoms to the alpine heights. Typically these are low growing plants that hug the ground surface and spread by densely spaced rooting stems called stolons. Rosy pussytoes is typical of this form. It forms a dense interwoven mat with numerous fibrous roots firmly anchoring it to the soil. Numerous spoon-shaped to broadly elongate leaves cover the horizontal stems and persist through the winter. Their gray green hue provides a pleasing textural effect.

    Leafy branching stems rise from the matted surface to a height of about 5-40 cm (2-16”) tall. Densely packed wooly hairs cover the stems. Stem leaves are mostly narrow, ranging from 0.5-3.5 cm long and end in a sharp tip.


    Antennaria rosea. Image courtesy of Stan Shebs.

    Half centimeter tall flowerheads occur in tight rounded clusters at the tips of the stems, each flower head soft and firm like a kitten’s toe. The flower head consists of modified leaves called bracts that surround a mass of tightly packed individual flowers. The bracts are very hairy at the base hence the softness. They also provide the colour, in the case of Antennaria rosea varying shades of pink. The whitish, true flowers emerge somewhat from the surrounding bracts in an attractive effect.  A close relative and sometimes considered the same species, white pussytoes (Antennaria microphylla) has mostly greenish to white bracts and is also a good garden plant. Males and females are on separate plants and flowers appear from June to August.

    Rosy pussytoes is a widely adapted plant growing throughout most of our province except the wet climates of Haida Gwaii and the central and north coast. The geographic range also extends to Alaska, Yukon and eastward to Quebec and southward to New Mexico and California. The natural habitat includes moderately moist to dry slopes, terraces along rivers, openings in forests, grasslands and dry sub-alpine meadows. It grows across a wide range of climates extending from lowland to high mountain elevations. We see rosy pussytoes occasionally during our expeditions to document the plants of BC’s northern mountains, where it appears on south-facing slopes just into the upper part of the subalpine zone.

    The species is widely adaptable to uses in open garden settings. In the book by Wendy Mee and other authors Waterwise: Native Plants for Intermountain Landscapes (Utah State University Press 2003) rosy pussytoes is recommended for rock gardens, small spaces and borders. To this I would add small eroding banks with poor soils and in and around paving stones. It tolerates a modest level of foot traffic. Make sure the soil has good drainage. Plants can be propagated like strawberries from rooted horizontal stems, best in the early spring or fall. Plant on loose gravelly soil to get them started. Propagation from fresh fall sown seed is easy, with seedlings ready to plant out in 4 months after germination. Rosy Pussytoes is hardy to zone 2 and can be grown in most gardens in BC.

    BC First Nations people of the southern interior had several uses for the plant. Dried roots were powdered, put into hot coals at winter dances and the smoke was believed to drive away bad spirits and revive passed out dancers. The leaves could also be chewed and swallowed to increase male virility.

    Expand your choice of ground covers beyond the common and sometimes invasive foreigners. Try rosy pussy toes as a native alternative.

    It’s a sunny November 14th, 2016. Halloween is a distant memory. Remembrance Day is still fresh in my mind. And now comes the season where shops compete with dreary songs to get us into the shopping, I mean christmas spirit. I used to hate this time of year – the rustle of dry cattails in my favorite swamps, heavy frost, the puddles with their morning skim of ice, the crisp air, Canada Geese flying off like bomber squadrons over the English Channel… It all meant one thing – snow and cold.


    Ah what am I saying, I live in Victoria now, we haven’t had snow in my neighborhood for two years now. Winter here is cool and wet, and on warm, sunny winter days you can still find lizards. Yes, the European Wall Lizard is active in winter as long as it is sunny. On November 14th, there were almost as many Wall Lizards crawling around as in summer. They were intent on basking, and given how warm the bedrock was in the sunlight, thigmothermy must play heavily into their winter behavior. Homeowners along May Street in Victoria say that Wall Lizards poke their heads out of rock walls as soon as the sun comes out in January. Other reptiles here emerge by late February to early March; the amphibians of southwestern BC are active all winter. Elsewhere in Canada amphibians and reptiles hibernate until mid-April at the earliest.

    As far as I know, the only month where we haven’t seen wall Lizards is December. Guess what my mission is this year?

    You guessed it – I am on the hunt for the elusive lézard d’hiver. I hope the solstice is sunny and warm… It’d be really fun to find lizards on the shortest day of the year.

    Who doesn’t love Lego? Lego is one of the greatest toys ever imagined by the human brain. Kits range from fantastically complicated, to incredibly simplistic. But the underlying element of completeness is the same. The kit must be complete to be built as the instructions suggest, but that doesn’t mean a Lego kit stays in its original configuration.


    Sometimes pieces vanish – but you can easily find substitutes. The more changes you make, the more obvious those changes become.

    It’s the same with nature. Ecosystems are incredibly complicated (such as the Amazon jungle) while others seem simple (the dune sea of the Sahara). Swat one gnat and you won’t see change in an Amazonian forest, remove a gnat species and you still may not see a change. Each missing species is far more obvious in relatively simple ecosystems. Fortunately, nature is resilient and has recovered from repeated perturbation and mass extinctions (the loss of many pieces (I mean species)) all the way to the present epoch (the Plasticcene ?).

    When you replace missing parts in a Lego kit, the final product will not be exactly the same, but will look reasonable and will hold together. You can look at the instructions to know what’s missing. You can swap parts from other kits (part 302126 is common to many Lego™ models). You can order replacement parts.


    In nature there is no list of parts to identify exactly what’s missing, and once things are lost, there is no mail-order replacement. Once something biological is gone, it is irreplaceable. Given enough time though, nature will fill an ecological void and restructure an ecosystem, but the ecosystem will never be the same. A restructured ecosystem may look unchanged to our eyes, but it is different in both function and species composition. Fortunately for us, change is the only constant in nature. Our origin (and subsequent invention of plastic – and Lego) and our continued existence on this plastic-polluted-planet, is a direct result of nature’s resilience.

    The loss of a Keystone Species changes the ecology of a region significantly. There are parts in each Lego kit which are critical to the model’s integrity, and in this sense, they parallel Keystone Species. Lose one keystone piece and your model won’t be as structurally sound, but will still hold together if there is built-in redundancy – in nature, this could represent the death of one cell in a phytoplankton bloom. You’ll never notice its absence. Organisms die every day and populations muddle on as nature permits.


    In this Lego™ model, there are several hinge parts per wing which keep the entire model together – the model has built in resilience. Imagine how the model changes as one by one, more of these hinge pieces go missing? Bit by bit, the wing joint weakens. Hinges have to interact with other pieces of the model to maintain the integrity of the entire population of Lego™ pieces. If the population of hinge parts is depleted, the wings will fall off.

    In recent years, large numbers of dead alcids are not an uncommon sight in the eastern North Pacific Ocean. The warm north Pacific conditions from 2012-2015 have correlated with mass mortalities all along the North American west coast. Rhinoceros Auklets and Common Murres have washed up right here in the Victoria region – this is not someone else’s problem. This Common Murre was found this summer and was photographed by Allan Eppler. Wings have fallen from our skies.


    The fishes that our alcids eat still exist along our coast – so why are marine birds starving? What piece of the ecolegological model is missing? The recent and rapid decline of plankton communities may be to blame. Phytoplankton feeds zooplankton, zooplankton feeds small fishes, and small fishes feed our alcids. These stumpy birds rely on small fishes like sandlance and herring, and in this way, are indirectly connected to phytoplankton (and so are we). Is the decline in phytoplankton populations having a trickle-down effect? Are local zooplankton and fish populations declining in concert with phytoplankton? Perhaps fishes have moved elsewhere (deeper? offshore?) to track phytoplankton and zooplankton blooms? Fishes may only be out of the range of diving birds at an energetically critical time in the bird’s year? Perhaps fishes are now less nutritious with changes in plankton communities? Is this a temporary change? What will be the feedback effect on the marine community if our alcids disappear? And is this the latest ratchet in our environment – a long-term trend in our coastal community creating the “new normal” for our grandchildren? All questions worthy of study.

    Temporary and permanent absence of a species has its effect in nature. The long term decline in oceanic phytoplankton communities has gone largely unnoticed by the majority of people – until its impacts rippled up the food chain and hundreds of emaciated birds washed ashore. Dead plankton sinks into the abyss every day – no one raises an eyebrow. But when a beach is littered with dead birds, we sit up and take notice. Each organism, microscopic or not, is a piece in the ecological integrity of our region, and the loss of each piece changes BC forever. Perhaps a Lego model is a poor analogy of the complexity of nature, but we failed to notice the loss of countless smaller parts, and only reacted when a continuing number of larger pieces washed up dead on our shores. I have to wonder what BC’s model will look like in 50 years. Have we already become unhinged?


    Who has a garden? Many of us do, and many nourish their gardens with manure. Each winter, my wife and I get a heaping truck-load of manure – a mix of sheep, horse and chicken excrement from our friend’s farm up in Central Saanich. Sure our yard is a bit fragrant for a day or two, but the manure matures in winter while our neighbour’s windows are closed. Manure as a source of fertilizer is nothing new.

    Watch any nature show on Africa and eventually you see scenes of Hippopotami (Hippopotamusses?) revving their tails to 30,000 RPM to spread their manure in their respective territories. Talk about leaving your mark on a place. But all that manure feeds fishes and is excellent fertilizer to increase productivity in their habitat. Streamside plants grow and the hippos have a convenient salad. Nature wastes nothing – not even waste is wasted.

    One of the RBCM’s curators also lives according to nature’s mantra – he wastes nothing. I bet by now you are wondering where this blog post is going.

    Every few days Grant Keddie combs through his scientific journals and cuts out articles to distribute to museum staff. This week I received an article from Grant from the journal NewScientist (page 6, 22 October 2016). The photograph tells it all – a Sperm Whale off-loading ballast as it dives, leaving a hazy russet cloud in its wake. The NewScientist article goes on to detail the role of whale feces in pelagic ecology. We rarely think about whale excrement – you know the old saying – out of sight, out of mind. If whales lived on land, we’d probably pay more attention to their gastrointestinal performance.


    Images from:


    Nutrients in the intestinal ejecta of cetaceans are a windfall to phytoplankton and perhaps zooplankton. Whale poop fertilizes the sea, boosting phytoplankton and zooplankton populations – I am assuming some crustaceans also are coprophagous (they eat poop particles). Plankton blooms feed krill and fishes, and these of course support a myriad of marine organisms. Krill is now a popular source of Omega-3 oils – hhhmmmm.

    Let it snow, let it snow, let it snow…

    We’ve known for ages that most of the deep sea is dependent on a flurry of fecal matter and decaying organisms from near the surface. Only the deep sea hydrothermal vent communities live independent of such gifts from the surface. But it surprises me that we are only recently celebrating our largest neighbors colonic contribution to oceanic ecology.

    The authors of the NewScientist article state that phytoplankton blooms supported by whale feces can help fight climate change (phytoplankton sequesters CO2). That seems to be a bit of a stretch, but their other claim that whales can increase local productivity and enhance fisheries certainly is interesting. In some areas of the world today (Norway, Iceland, and Japan), and within my lifetime here in BC, we have killed whales for oil but also to avoid sharing the ocean’s bounty. Yes, we killed whales to limit their impact on our fish harvests. If whale wastes enhance fisheries, removal of whales starved our coastal community.

    In John Ford’s handbook of Marine Mammals of BC, he states that 25,460 whales were killed in our waters in the 20th century. I don’t have the global harvest estimates from the 1700s to present day, but whale losses run in the hundreds of thousands. In terrestrial terms, imagine trying to grow a garden without fertilizer? Now think how removal of a significant number of whales impacted the marine phytoplankton community. I have always wondered about the effect of losses of thousands of whales (and hundreds of basking sharks) on planktonic communities in BC, but the ecological joke is on me. I always looked at it from the top down, not the bottom up.

    Large animals, such as mammoths, mastodons, horses and camels that roamed North America near the end of the ice age are referred to as mega-fauna. Why these large animals went extinct has been widely debated but answers are beginning to emerge.

    New information is showing the answer is more complex than previously thought. Both climate change and human hunting play a role at different times in different places.

    This was a likely scene around Victoria, British Columbia for a 300 year period between 11,700 and 10,900 years ago when an open parkland environment provided habitat for herds of bison. A subsequent cold period saw their disappearance from Vancouver Island.

    Expanding and Shrinking – Habitat and Genes

    Before the appearance of humans on the northern landscapes we see that ecosystem stability for animal species generally persisted over long periods of time. During repeated sudden climate changes over the last few hundred thousand years of the Pleistocene (2.6 million to 11,700 years ago) animal populations had the ability to disperse across the landscape to shrinking refugia during harsh times and expand back to increasingly more favourable habits during good times. During cold periods, when the sea level was lower by as much as 150 meters, the Beringian continent was as wide as the Canadian Prairies.

    The evidence for shrinking environments is seen in the reduction of genetic diversity in large animals such as mammoth, mastodon and bison. Grass loving animals of the far north were displaced with the expansion of boreal forests during the onset of warm periods. Boreal forest loving mastodons disappeared 70,000 years ago from large regions of the north with the advance of colder climates and the return of an open tundra environment. By the time humans appeared on the scene mastodons only lived much further to the south.

    Animal populations were often drastically reduced in numbers, before sub-populations made a comeback. This pattern of population reduction and expansion happened especially during rapid warming periods. The appearance of humans in the region may have destabilized this pattern of population regeneration by restricting the movements of animal populations.

    Human Interference

    Humans likely interrupted the ability of mega-fauna sub-groups from connecting with each other. This would be especially true if humans were concentrated on regular migration routes between or living on resource rich areas used by the animals. The concentration of large game animals in smaller regions would make them more susceptible to predation from carnivores and humans.

    Some mammal species whose ranges straddled the length of Beringia became extinct on one continent, but not the other, with the rise of sea level at the end of the Pleistocene. Examples are the horse (Equus caballus) and Saiga antelope (saiga tatarica) that survived only on what became the Old World side of the Bering Strait.

    Humans co-existed for several thousand years in eastern Beringia – the area now including Alaska and the Yukon. During this time mammoths and horses disappeared but muskox, bison and caribou survived.

    Further south large animals were faced with rapid environmental change and increasing human and carnivore predation. In the American Southwest mammoths experienced a warm and dry climate that would have made their seasonal movements more predictable and more vulnerable to predation. Large scale predation of mammoths and mastodons is often associated with a culture called Clovis that was only around for a short time period of 300 years from 13,200 to 12,900 years ago. The Clovis culture is recognized by distinct types of spear points. Other cultures before and after the Clovis culture also hunted mammoths, but our knowledge of these cultures is still developing.

    The megafauna diversity of North America and Eurasia was considerably reduced around the time of the transition from the ice age to the more recent Holocene period after 11,700 years ago. By this time the woolly mammoth (Mammuthus primigenius) became extinct in many regions in both North American and the Eurasian continent. The last mammoth survivors on Wrangle Island northwest of the Bering Strait disappeared only 3700 years ago when we see the first evidence of human occupation of the Island.

    Muskox in British Columbia

    For a few years now I have known of European Wall Lizards (Podarcis muralis) along the back of Borden Mercantile here in Victoria. There are adults and yearlings in spring, and by late summer, many newly hatched lizards can be seen running around in old pallets and in the rubble behind the store. My student Kelsey also let me know that European Wall Lizards could be found along rock retaining walls at 1000 McKenzie Avenue in the same general area as Borden Mercantile. The first lizard I saw at Borden Mercantile dates back to 2014.IMG_2896













    Obviously I needed to explore and find out whether these were isolated introductions, or part of a larger population at the Quadra-McKenzie intersection. When my wife and I are picking up garden supplies at Borden Mercantile, I don’t get much time to explore for lizards. We have a 3-year-old who keeps us busy. It was hard to find the time to wander around the region at the Quadra Street-McKenzie Avenue intersection to see how far the lizards had spread. Until now.

    The Google Earth image below shows the result of an afternoon’s exploration (Monday April 25th, 2016). Yes – I went for a walk and did some “lizard watching”. The original locations I knew about are in GREEN. The RED dots are new.


    The Saanich municipal yard is crawling with lizards – so that begs the question – did wall lizards arrive at the municipal yards first, and then spread to Borden Mercantile? It seems likely since the Hartland Landfill and Saanich itself is now infested with these invasive lizards. We’ll never know how the lizards travelled to this area. Perhaps they were stow-aways on trucks that move between the Hartland Landfill and the municipal yards. They could have been dropped there inadvertently by homeowners dumping lizard infested garden waste. Who knows. But the fact is, this area now has a firmly established population. In a short afternoon’s walk I saw juveniles from last year, adult males and females, and plenty of gravid females – so the annual population boom will happen again as this year’s eggs hatch.

    The lizards also are easy to find along the isolated rocks and bedrock outcroppings along the Lochside Trail. Perhaps that trail and the ditch that runs through the Saanich municipal yards will serve as dispersal corridors. It is almost a straight line along the Lochside Trail to Swan Lake Nature Center – I wonder how long it will be until that nature reserve is overwhelmed by invasive lizards?


    Whenever we receive new specimens at the RBCM, we hope to have enough collection data to make the specimen valuable to science. The bare minimum we need is the date collected, a description of the collection location, and if you have latitude and longitude for the collection site – GREAT.  Our Mammal and Bird Preparator was sorting through some of the newer specimens in the receiving freezers – and this label stuck out:


    There’s the date, a location, even a cause of death – a drowning victim.

    That’s a source of mortality that someone should study – in-ground pools as a man-made source of wildlife mortality. I remember seeing a Barn Swallow trying to swoop low and drink from a pool on a still summer day. It lost track of the surface and “landed too low” (if I remember my WWII aviation slang correctly). It actually did an end-over-end into the pool when its beak dug too deep into the water’s surface – and since we were in the yard, we were able to save the bird.

    But I digress.

    A key feature of a specimen label is clarity. I am just as guilty as anyone else in our modern day rush-rush society – and have scribbled labels much to fast. The above label is great – it looks like 49°48’06.148″W, -119°30’15.217W – or is that North? Woah – 119°N? The earth must be doughnut shaped…  I remember a student giving a lecture on cod when I was a grad student and she said that Arctic Cod (Boreogadus saida) ranged to 95° North. Could it be true? Is the Earth doughnut-shaped and its coordinate system goes beyond 90 North?

    Old museum labels also suffer from the same problem – before we printed labels, we relied on perfect handwriting to make sure that 100 year old labels would still make sense. When the pen fades, it can be a real challenge to decipher the original content on an oily bird label. Signatures are easy to figure out – they usually show each researcher’s distinctive flare. But a lazy 6 or a 9 can look like a zero, a faded 7 can look like a 4, a 1 like a 7, a Z like a 2, etc…

    To all citizen scientists – please write your labels as clearly as possible or print them out on your home computer. Our collection’s scientific value is totally dependent on your data.

    Yea – I know this specific label is detailing a location in Upper Mission at 49°48’06.148″N; 119°30’15.217″W – but if the N and W were obvious on this label, we’d have not had such a chuckle. It does however, highlight how handwriting can seriously change the interpretation of a label.




    It is always fun (as a sci-fi fan) to find things in the RBCM’s collection which take me away from tasks like fish vat inventory, to allow a brief respite in geekism.

    Sure there are simple things – like finding specimen 2187 and making the nerdistic reference to Finn’s stormtrooper number and Princess Leia’s jail cell. In the vertebrate collection, 2187 is the catalog number for a Columbian Ground Squirrel collected in 1937, and a Mallard Duck from 1915. There is no reptile or amphibian with that number – the highest catalog number in the herpetology collection is 2007. There’s also no fish with that number; fishes have complex catalog numbers which reflect the year the specimen was collected, the sample lot in that year, and the nth species in that specific lot. I plan to simplify the fish catalog numbers – so eventually there will be a fishy 2187 and it will have a fin.

    But in January, while sitting with my head in a vat of fishy alcohol, counting far too many flatfishes, I found a few little gems that made me snicker. The same cannot be said for my volunteer – she just rolled her eyes – and said “Nerd” (or something like that…).

    The following photos are of some flatfish I found in vat 16. This Arrowtooth Flounder (Atheresthes stomias) is number 7 of 9 in its respective sample (980-00573-004). Cue the snickers from the Trekkies. Resistance is futile.


    Another fish, the Pacific Sanddab (Citharichthys sordidus) – the genus is pronounced Sith-a-rick-thees – Yes, it’s a Sith-fish… it has a dark side and a light side… and the Star Wars fans go wild with excitement. Smiling now? It just goes to show that with nerdy humour, a little dab’ll do ya.


    Yes, there are days where work is frantic and the day flies by – no complaints there. Then there are days where 4:30PM seems like a lifetime away. On those days, doesn’t matter where you work – little moments of levity go a long way. Nothing beats a slow but productive day punctuated by silly humour. Life is too short to be serious all the time. Seriously.

    I did not expect this much attention when we developed the prototype Pocket Gallery here at the RBCM. Who’d have thought that the Assfish would go viral. This morning (January 19, 2016), I received an email from Dr. Andrew Gates of the SERPENT Project, Southampton, with a video of a live Assfish from 2601 meters off Africa’s east coast.

    Now we can see the fish in its natural habitat – swimming lazily over a soft substrate – until it was startled by the ROV/submersible.

    Their home page can be found at:

    And here is CHEK news’  This Week in History on the Assfish:

    The Assfish has proven itself very popular – no if’s, and’s, or but’s.





    Whether we notice or not, we rely on natural cycles for our very existence. While many pay scant attention to nature, it provides life-support services (food, timber, clean water, flood control, pollination, fresh air) as well as spiritual functions (serenity and beauty)(Heal et al. 2001).


    Only in Science Fiction can you find a planet with plenty of food and air but no green-spaces. Where does that atmosphere come from? Is all the food shipped in from other planets? Call me crazy, but I’d rather be on the 4th moon of Yavin (it looks strangely like the Yucatan region).

    The stability of our planet’s ecology is based on diverse ecosystems. Even seemingly barren habitat, as found in alpine lakes, is far more complex than first glance suggests. In these low-productivity (oligotrophic) lakes there can be complex communities of predatory and grazing zooplankton, as well as a diverse assemblage of algae and microbes.


    At home in my urban yard there is a lot of diversity – and we’d like to attribute that to our lawn-removal plan. A complex environment – even if only a veggie garden, should attract more wildlife. This last weekend (November 8th) we had a Wilson’s Snipe hang around, in addition to the usual birds like the Golden-crowned Sparrows and Dark-eyed Juncos that forage in our garden on a daily basis. We estimated about 30 birds on the food forest this morning – Juncos, Golden-crowned Sparrows, and a Towhee – but not a single bird on the nearby lawns. It made me wonder what we could do for North Americn bird populations if everybody abandoned the concept of a lawn and grew a garden that was far more complex and full of food.


    We also get a few mammals in the autumn – Grey Squirrels, Norway Rats, Raccoons, and Mule Deer – actually they live year-round in our neighbourhood. We get the occasional Cougar as well, but I have never seen one. The Cougars must be after the Mule Deer, Eastern Cottontails and domestic cats that are allowed to roam free. Predator-prey interactions are commonplace even in urban environments. I have seen many people walk by oblivious to life-and-death “dog-fights” between Cooper’s Hawks and small passerine birds. These interactions add richness to our communities and can make a short stroll very exciting.

    During these grey rainy winter days (or snowy days elsewhere in Canada), it is hard not to daydream about summer, or a tropical get-away. But even in the daily rush to and from work, you can admire the resilience of nature – from Equisetum poking through newly patched sections of sidewalks in Victoria, to a Common Redpoll adding its dash of colour to a frosty prairie hedge. Take the time to appreciate nature as it prepares for the shortest days of the year.
