AQUATIC AMPHIBIAN EGGS OF BC’S SOUTH COAST
Triantha occidentalis, with its dainty white flowers appears innocuous, but its sticky stem helps the plant trap and make a meal of tiny insects. [Danilo Lima]
A pretty little white flower that grows near urban centers of the Pacific Northwest turns out to be a killer.
The bog-dwelling western false asphodel, Triantha occidentalis, was first described in the scientific literature in 1879. But until now, no one realized this sweet-looking plant used its sticky stem to catch and digest insects, according to researchers who note in their study published Monday it’s the first new carnivorous plant to be discovered in about 20 years.
“We had no idea it was carnivorous,” says Sean Graham, a botanist with the University of British Columbia. “This was not found in some exotic tropical location, but really right on our doorstep in Vancouver. You could literally walk out from Vancouver to this field site.”
Fewer than 1,000 plant species are carnivorous, and these plants tend to live in places with abundant sun and water but nutrient-poor soil.
Graham’s team was doing an unrelated project on plant genetics and noticed that the western false asphodel had a genetic deletion that’s sometimes seen in carnivorous plants. The researchers started to think about the fact that this flower grew in the kind of environment that’s home to various other insect-eating plants. “And then they have these sticky stems,” Graham says. “So, you know, it was kind of like, hmm, I wonder if this could be a sign that this might be carnivorous.”
Bees, large flies and other major pollinators are likely too big to get caught by the sticky stems of Triantha occidentalis, researchers say. But smaller midges aren’t so lucky. To see if the plants could actually take in nutrients from insects, researcher Qianshi Lin, now at the University of Toronto, Mississauga, fed fruit flies nitrogen-15 isotopes, so that this nitrogen could be used as a tracker. He then stuck these flies to stems of this plant.
Later, an analysis showed that nitrogen from the dead insects was indeed getting into the plants. In fact, Triantha was getting more than half of its nitrogen from prey. In the Proceedings of the National Academy of Sciences published online Monday, Lin and his colleagues say that this is comparable to what’s seen in other carnivorous plants. What’s more, the researchers showed that the sticky hairs on the flower stalk produce a digestive enzyme that’s known to be used by many carnivorous plants. And when the research team looked at specimens of this plant preserved in herbariums, they found small dead insects stuck to the stems.
Aaron Ellison, a botanist with Harvard University who was not part of the research team, says the discovery was the result of “a really nice chain of scientific thinking.” All the other known carnivorous plants capture prey with the help of modified leaves, he notes.
“Nobody would be looking at a flower stalk as the primary mode of carnivory,” Ellison says. “That is quite a surprise.”
Usually carnivorous plants keep their deadly traps far away from their flowers, so there’s no danger of accidentally killing off pollinators. But in this case, it looks like the stem is only able to ensnare tiny insects such as midges, not the larger bees or butterflies involved in pollination. The plant doesn’t just grow in Canada; the researchers note in their study that the flower is found near “several major urban centers on the Pacific coast.”
The whole experience has Graham wondering what else is out there secretly eating insects. After all, it’s not that uncommon for plants to have sticky stems, which are thought to be used as a defense mechanism to keep insects from eating the plant. “I suspect,” Graham says, “that there might be more carnivorous plants out there than we think.”

Bringing back beavers
Joshua Harris | 20th January 2020
Rivers are interesting things. They flow inexorably towards the sea, carrying what was once billions of raindrops, in huge web like networks fanning out across the landscape.
They braid and meander, changing their course imperceptibly slowly.
But how have rivers changed over time, and how did this affect the species living within them?
In the Cambrian and early Ordovician periods (before around 450 million years ago), the continents were bare. Plants had not yet colonised the land, and without the weathering caused by their roots, there was no soil, only loose rock, gravel, and sand.
Sedimentary records tell us that the rivers at this time were braided: split into smaller streams rapidly shifting across the riverbed, leaving behind characteristic alternating layers of fine grained and coarse grained sediments.
Today, these kinds of rivers are found in the Arctic and high mountains – places where there is no vegetation to stabilise the riverbanks – as well as on beaches. When there is heavy rainfall, the whole channel is submerged and a new pattern of streams appears when the waters subside.
When plants gained a foothold on the land, things began to change. Even the liverworts, diminutive slimy things which you might find on a damp boulder, had an impact on the structure of rivers.
By weathering the top layer of rocks, they created clay. This cohesive mud resulted in more stable riverbanks, which slowed down the sideways migration of the channels. The clay also created soil, which allowed more sophisticated plants to colonise. Their root systems further stabilised the floodplains, forcing braided rivers into more defined and slowly meandering channels.
The next big change came with the origin of trees, which by the Carboniferous period were covering vast areas of river deltas (and, as they fell into the anoxic swamp, forming much of the world’s coal).
Rivers would have often become blocked by fallen trees and piles of debris. Blockages force the current sideways, carving out new channels into the floodplain.
The result would have been a complex shifting mosaic of channels, oxbow lakes, and swamps in various stages of vegetation succession.
It was in similar shallow swamps (although slightly earlier, in the Devonian period), that Acanthostega, thought to resemble the ancestor of terrestrial vertebrates, would have clambered through the waterweed and maybe occasionally wriggled onto land. Today, rivers of this kind can still be found in undisturbed parts of the Amazon.
It’s not just plants that have influenced the changing patterns of rivers, but also animals, and none has had more impact than the beaver (apart from, of course, humans).
The first beavers evolved in the Eocene period, around 45 million years ago. By building dams, beavers slow down the flow and promote the creation of new channels as the water spills out sideways. They create mosaics of habitats – ponds, riffles, marshes, wet woodland.
The huge variation in physical environments – speed of flow, the depth and width of channels, size of sediment grains, water temperature – creates niches for many kinds of animals and plants.
Whilst a beaver swamp may appear as one habitat when viewed from our perspective, at a finer scale there are myriad different microhabitats, a huge amount of variation crammed into a small space.
We tend to overlook the effects that living organisms have on their physical world because most of the ecosystems around us have been “downgraded” as we have removed the important species – thus, in these cases it is mainly physical processes that determine how organisms survive.
But there is now an increasing weight of evidence that the interaction works both ways: the earth shapes life, and life shapes the earth.
Beavers’ engineering work benefits many kinds of wildlife: ponds are perfect for frogs and fish larvae, riffles and gravel banks for dippers, swampy areas for water rails and moorhens, dead trees for woodpeckers and owls, and lush coppiced vegetation for songbirds.
The fact that beaver habitat is ideal for so many species should not come as a surprise: beavers were present in our ecosystems for millions of years, so many wetland species may have actually evolved to live in beaver habitats.
Through studying the effects that beavers have on streams, it has become clear that deeply incised river channels disconnected from their floodplain, which we perceive as the norm, are in fact a consequence of the removal of beavers, and other human impacts.
Before we deforested and farmed the land and hunted beavers to extinction for their fur and scent glands, wetlands would have filled the bottoms of valleys, with snaking channels, ponds, wet meadows, and willow scrub.
By bringing back the beaver, and allowing our rivers to freestyle through the landscape, we could revive these incredible ecosystems. Beaver engineered wetlands could fan out into every valley in an interconnected network, like arteries pumping life back into the landscape.
So many other species could flourish in the habitats that beavers create: otters, water voles, marsh tits, spotted flycatchers, lesser spotted woodpeckers, water rails, egrets, lapwings, redshanks. Incredible species which we’ve almost forgotten could return – white tailed eagles, cranes, and even white storks, which last bred in the UK in 1416 but are just starting to make a comeback.
Whilst large areas of wild land may always remain distant to most of us, beavers could create pockets of wildness nearby.
The thrill I experienced when squelching through a beaver swamp in Devon was definitely the highlight of the past year. Experiencing these messy, exuberant living landscapes could rewild our own lives and so reconnect us with nature.
This is especially important for younger generations, because people will not care about the living world unless they experience it at a young age. In the words of the lepidopterist Michael Pyle, “What is the extinction of a condor to a child who has never seen a wren?”
A revival of beaver ecosystems would have wider environmental and economic benefits beyond increasing biodiversity and bringing wildness back into our lives. Their leaky dams hold back water in floods, and release it gradually in drought.
By retaining water in the headwaters of catchments where the land is less valuable for farming, they could protect more productive arable land further downstream. As we experience more extreme weather events due to climate change, reintroducing beavers to our river systems could make a valuable contribution to reducing the damage to villages and towns.
The lush swamps that beavers create have been shown to filter out fertiliser and pesticide runoff, and reduce the washing away of soil to the oceans – something which is currently visible from space whenever heavy rain falls.
As vegetation builds up in the ponds it forms peat, and the carbon that was sequestered by the growing plants is locked away.
We’ve spent thousands of years trashing the complex connections in our living world, and we’ve created ecosystems which are a mere shadow of their former selves.
If there is one animal which we need in Britain right now, it has to be the beaver. The bang for your buck in terms of biodiversity and wider environmental gains is huge.
Beavers transform their world so profoundly that they are like a fully automated tool for ecological restoration. We only have to release them and let them do the work.

Times Colonist Nov 7th 2019 article: Wetlands Restoration
Regarding Canada: [from wikipedia] Ramsar Convention “This is a list of parties contracting to the Ramsar Convention on Wetlands of International Importance especially as Waterfowl Habitat, which is also known as the Convention on Wetlands. The Convention’s mission is “the conservation and wise use of all wetlands through local and national actions and international cooperation, as a contribution towards achieving sustainable development throughout the world”. It calls upon contracting parties to recognize the interdependence of humans and the environment as well as the ecological functions of wetlands, such as wildlife habitat, nutrient cycling, and flood control.
The Ramsar Convention is the oldest multilateral international conservation convention and the only one to deal with one habitat or ecosystem type, wetlands. The Convention’s headquarters are in Gland, Switzerland, and it works closely with the International Union for the Conservation of Nature.”
Canadian sites for Ramsar wetland of international importance:
Wikipedia: “As of 2016: there were 2,231 Ramsar sites, protecting 214,936,005 hectares (531,118,440 acres), and 169 national governments are currently participating.” Canada’s has 37 sites, a vey good ranking on the international list.

Without bats, economy will have trouble flying by Cori Lausen
JANUARY 4, 2017 / TIMES COLONIST
After they replaced their Halloween décor with inflatable Santas and reindeer, most people probably never gave another thought to bats. But this winter could be life-changing for many B.C. bats — and not in a good way.
The recent discovery of bats infected with white-nose syndrome in a location in Washington state just over the border from B.C. could spell disaster for our bat populations. The syndrome has killed millions of bats in eastern North America over the past decade, but until the Washington discovery, had not been detected on the West Coast.
A disaster for bats would also be a disaster for our economy. Bats are voracious consumers of insects. In fact, bats are the No. 1 consumer of night-flying insects. With many, many fewer bats circling our night skies, those insect populations are likely to explode, and that means significant damage to crops and trees, and even unpredictable changes to fisheries.
A U.S. study found that bats provide up to $53 billion a year in pest-control services for the agricultural sector alone in the United States.
Here in B.C., bats consume many moths that damage trees, including the caterpillars and moths of the spruce budworm.
Many of the insects that bats consume start life as aquatic larvae, which are food for many freshwater fish. Shifts in insect densities and diversity can produce similar shifts in fish species.
A massive die-off of bats is going to change these patterns in ways that are hard to predict. It might mean greater reliance on artificial pesticides in agriculture or more areas of forest stripped of vegetation. Without bats controlling biting insects such as mosquitoes, we could also see an increase in cases of insect-borne diseases, such as West Nile disease. And it will mean more pests in our garden and more uninvited guests at our summer barbecues.
Sadly, there is a very strong probability that the syndrome will flare up in B.C. this year. The disease makes the odds of winter survival extremely long for bats. Bats with the syndrome are infected with a fungus that eats at their wings and forces them to burn through their precious stored winter fat long before the return of the insect season. It spreads throughout hibernation sites, and can kill up to 90 per cent of resident bats.
Bouncing back from the devastating impact of white-nose syndrome is not going to be easy for bats.
While to some, bats seem like mice with wings, our only flying mammal has more in common with grizzly bears, bearing only one young each year and living 20 to 40 years.
In B.C., we are lucky to have the widest diversity of bat species in Canada, with at least 16 species, seven of which are found only here. But that diversity is not going to protect our bats from white-nose syndrome. We know at least two species found here have already been devastated in the east. Fourteen of the species found in B.C. hibernate, meaning the vast majority of our bats are vulnerable to the disease.
With the arrival of white-nose syndrome, it is critical that we give bats — and those who depend on their services — a fighting chance. That means identifying and protecting key habitat areas, working with industry to manage things such as old mines that bats use for hibernation, and continuing to build our knowledge of bat activity and populations across the province.
Right now, the provincial government does not have a plan for dealing with white-nose syndrome, and provincial species-at-risk staff are spread incredibly thin, with not a single provincial-level biologist having the time or the expertise to deal with bats.
We do have a plan, which we developed in partnership with other concerned biologists across B.C.
Along with the B.C. Bat Action Team, we need to swing this plan into action, but we can’t do that without the resources and support of the B.C. government.
Time is of the essence, and resources are needed to make progress. We might not be able to knock out white-nose syndrome with a single “kapow,” but if the government commits resources more in keeping with the scale of the problem, we can reduce the disease’s impact and help bats recover.
The threat is on our doorstep. Let’s not wait until it has entered the house to spring into action.

Soils are the foundation for our food production and existence. It is important to use good practices that not only protect the soil, but also replenish its nutrients. Soil is the most undervalued resource to humans. The United Nations estimates that globally we lose 50,000 square kilometers of soils, an area the size of Costa Rica, each year.

Noxious Weed Alert
Shiny-geranium [Geranium lucidum] information can be found at:
Shiny geranium, also called shining crane’s bill, is a low-growing annual Eurasian plant that has escaped from gardens into wild lands…
It resembles other weedy geraniums such as herb robert (Geranium robertianum) and dovefoot (Geranium molle), and can quickly spread and overwhelm open to semi-open habitats.
Plants can be carefully hand-pulled or dug out before they are in seed, but take care to remove as much root and stem as possible to prevent plants from re-sprouting. *
Flowers Low-growing annual with small, pink, 5-petaled flowers that grow in pairs on little stems
Leaves are shiny (especially later in the season), round to kidney-shaped with 5-7 lobes (that are themselves shallowly lobed)
Sepals (around the base of the flower) are keeled (stick out) with noticeable cross-ribs
Shiny geranium vs Dovefoot (Geranium molle) – Stems are reddish and not hairy, up to 20 inches tall
Bloom time is spring to late July
Resembles the common yard weed called dovefoot geranium (Geranium molle) but dovefoot’s petals are deeply notched (looks like the flowers have ten petals instead of five), and dovefoot is more fuzzy and the stems are less red.*

“For many people who aren’t sure what they can do about climate change, home gardens provide an opportunity to make a palpable difference.
That sense of purpose is creating a change in garden esthetics, with a more natural look and more emphasis on drought-tolerant and wildlife-friendly plants.
… Unless we share our space with nature, the plants on which bees, caterpillars, butterflies, birds and other wildlife depend will not survive,” Tallamy said [Douglas Tallamy, University of Delaware].
Earth-friendly gardens consist mostly of native species, on which local wildlife depends, experts say.”

Naturespeak: Skunk cabbage is a bear’s BFF
NATURE’S EX-LAX Bears are one of the few animals that eat the buds and leaves of Skunk cabbage. It helps get their digestion moving after hibernation.
Long before bears stir in their dens, before salmonberries bloom pink on woody stems and vine maples unfold their leafy fans, skunk cabbage periscopes through wetlands.
Its yellow flower is the first sign of spring. Green leaves quickly unfurl and emit a pungent skunk-like odour that is hard to miss. The uninitiated will hold their noses and exclaim, “It stinks!”
The BFF of bears and early pollinators, skunk cabbage blooms before bees are active. Because of this, it attracts its own entourage with a foul stink. The smell comes from its leaves — when bruised they release a scent that attracts flies and beetles. Mistaking the odour for a rotting animal to lay their eggs on, they seek out the flower hidden within the hood-like leaf, which is called a spathe. And when they do, they transfer pollen from male to female plants.
It’s also a warm shelter to rest in, since skunk cabbage literally heats up air around it. If you were to put your finger inside the spathe at the right time and touch the flower, your fingertip would get warm. For a period of almost two weeks, the air temperature surrounding skunk cabbage can increase by up to 20 degrees. The heat skunk cabbage creates rises and helps to spread the odour, attracting more insects to this hotspot and making skunk cabbage as popular with some bugs as charging stations in airports.
Skunk cabbage is sometimes known as bearweed, as bears are one of the few animals that eat the buds and leaves.
When bears awake after hibernating, they haven’t defecated in a long time. Prior to hibernation, they ingested leaves, hair, dirt and needles to form a fecal plug up to a foot long in their lower intestine. When they wake up, they need to become unplugged before they can feast on grasses and grubs.
Enter skunk cabbage, nature’s Ex-Lax. Bears eat the plant to get things moving again. But don’t think about trying it yourself: the juices of its leaves cause serious inflammation in the mouth.
Skunk cabbage reminds us that bears will soon be sharing our favourite trails again, so when you start to see skunk cabbage around, remember to make noise and be aware of your surroundings.
Skunk cabbage is the guest that shows up early for the party, then slips out when it is in full swing. By the time berry season hits, its 1.3-metre tall leaves will have decayed and dissolved back into the muck it came from.
In its dreadlock of roots, it stores energy for next spring, when it will rise out of the ground like something out of a B-grade horror film and win over the flies and the bears (and maybe even you) with its unforgettable scent.

About Bats in the Capital region
While there are about 10 species of bats in the region, they all have a few things in common:
All our bats are insectivores, menaing they all eat bugs. In fact, they eat more insects than any other nighttime predator. No bats in Canada eat fruit or blood.
All our bats are relatively small. Most bats with their wings spread are smaller than adult’s outspread hand, though a few grow up to 20cm.
All are suffering from major habitat loss, including loss of important feeding areas on streams and wetlands, and roost areas in wildlife trees.
All are long-lived (over 30 years for some species) and reproduce slowly. Most species have only 1 baby each year, though a few species are known to have twins.
Several of our bat species are considered to be at risk, including the Keen’s Myotis and Townsend Big-eared Bat. The Little Brown Bat has been recommended for Endangered status by the Committee on the Status of Endangered Wildlife in Canada due to dramatic population losses from White Nose Syndrome in Eastern Canada.
There are 10 known species of bats on Vancouver Island, and all of them face threats from habitat loss, predatation by cats, and from the future arrival of White Nose Syndrome. Unfortunately, we know little about habits and population of bats on Vancouver Island. HAT’s Community Bat Program is working to better understand bats in the Capital region, and helping homeowners with bats in buildings find ways to live with the bats, or exclude them in way that does not harm them. Learn more about how you can help our local bat populations. HAT’s program is part of the Community Bat Programs of BC.
What can I do to help bats?
HAT needs volunteers and participants to record bats as part of the Annual Bat Count.
Contact us at 250 995-2428 or email firstname.lastname@example.org to find out what to do.
We need reports of bat colonies in the region. If you know of a colony, please contact us. We also need volunteers to monitor colonies so we can learn about them.
Place a bat house on home, an outbuilding, or on a pole in an open area on your property. Information on bat houses, including plans for making the houses and notes on placement, can be found at the Community Bat Programs of BC website.
Knotweed in CRD
Knotweed has destroyed the foundations of homes and roadways. Don’t try to remove the plant yourself. Cutting mowing and pulling the plant stimulates it to grow further.
It has been spotted in all CRD municipalities except the Highlands.
DO NOT COMPOST! Home composting is likely to increase the spread of this invasive plant.
