Nominate a tree for the 2022 CVN Tree of the Year

In this fifth year of our Tree of the Year contest, we continue with the improvements made last year, including:

  • Any resident of the Comox Valley can nominate a tree, not just CVN members.
  • We have an online nomination form to make nominating easier.
  • The winner will be decided by public vote. All residents of the Comox Valley can vote for their choice among the nominated trees using online voting.

You can nominate a tree any time between February 1 and April 1. Visit our Tree of the Year page to learn more about the contest and to access the nomination form. There you will also find some clarifications of the nomination rules.

After nominations close, we will publish an illustrated list of the nominees on this website, along with maps of their locations. We encourage you to visit as many as you can, preferably by cycling or walking, before you vote.

Voting will open in late April and run until the end of May. Watch for additional details at that time.

More Nordic botany

From an email by Jocie to the Botany Group on January 22.

Here are a few more trees from the subalpine (photos from the Jutland nordic ski trail).

One of my favourite trees is the amabilis fir (Abies amabilis). The silvery bark, dark green needles, and spicy fragrance are emblematic of the mountain wilderness. They evoke the deep forests of the past that covered much of Vancouver Island just a few centuries ago.

Amabilis usually has somewhat flattened needles, a bit like a grand fir, but it has a double row of needles along the center. Like all “true firs,” amabilis has smooth bark (when young) and bumpy resin blisters.

Another common tree of the subalpine in our area is the yellow cedar, Callitropsis nootkatensis (formerly: Cupressus nootkatensis). The seed cones look like little round berries, and are light green when young and chestnut brown when mature. Tiny male pollen cones dot the tips of the branches.

Branches of yellow cedar tend to hang straight down like a curtain, unlike the fanning branches of red cedar. Yellow cedar is also found at sea level and becomes more common along the coast as one heads north.

Have a closer look at these wonderful trees the next time you are up the mountain! [Click a photo to enlarge it.]

Nordic botany

From an email by Jocie to the Botany Group on January 17.

I was up the mountain on Saturday, x-country skiing on the upper west-Jutland loop. The conditions weren’t great…it had rained heavily up there a week or so ago. Most of the nordic skiers seem driven to get from A to B as fast as possible. I like to putter along and look at things, take pictures, ponder ancient trees etc. Those hurried skiers don’t know what they are missing!

Anyway, here are a few highlights. [Click a photo to enlarge it.]

  1. Snow pitted with rain.
  1. Frosted subalpine fir: note the upswept bushy needles.
  1. Frosted white pine needles.
  1. Mountain hemlock with garlands of hair lichen (Alectoria, Bryoria, etc).
  1. Wolf lichen – I think, (Letharia vulpina): the bright yellow patch on the right of the snag.
  1. Ancient yellow cedar snag detail.
  1. View of Albert Edward & Divers/Rossiter lakes.
  1. View of Alexandra Peak (the “thumbs up” mountain): Sadly, this range of mountains is not in Strathcona Park.

Learn about the BC Parks iNaturalist Project

Comox Valley Nature is pleased to host the following free online lecture:

Title: Using iNaturalist to document biodiversity patterns in BC Parks
Speakers: Dr. Brian Starzomski and Kate McKeown
Date: Sunday, January 16, 2022
Time: 7:00 p.m. PST

This webinar is facilitated by the Canadian Society of Environmental Biologists and is open to the public (see the registration link below).

iNaturalist is a biodiversity database and social media platform. It has revolutionized community science by making it easy and fun for anyone to contribute to the collection of biodiversity data, any time they’re out enjoying nature. A dedicated community of identifiers helps to refine the accuracy of the species IDs.

iNaturalist is a wonderful addition to biodiversity inventory in British Columbia where the species diversity is greater than anywhere else in Canada. BC is vast, and traditional data collection methods alone cannot survey all corners of the province. To fill in some of these gaps and provide opportunities for anyone to collect biodiversity observations and hone their natural history skills, Dr. Brian Starzomski (UVic) and Dr. John Reynolds (SFU) teamed up with BC Parks and the BC Parks Foundation to create the BC Parks iNaturalist Project. BC Parks iNaturalist data are fast becoming a large and valuable source of biodiversity information in BC, and it is all due to the great work of more than 6,000 keen citizen scientists.

To date, the BC Parks iNaturalist dataset consists of almost 500,000 observations and more than 9100 species! The dataset keeps growing, and observations are routinely used in threatened and endangered species assessments by the federal Committee on the Status of Endangered Wildlife in Canada (COSEWIC).

So far, the top three parks for observations are Strathcona Provincial Park, South Okanagan Grasslands Protected Area, and E. C. Manning Provincial Park. All 1035 BC provincial protected areas (including parks, conservancies, and ecological reserves) are listed in the BC Parks iNaturalist project, but 400 have fewer than 10 observations: there is much more work to do!

This is an excellent opportunity for you to learn more about the value of iNaturalist and citizen science for describing patterns of biodiversity in BC Parks.

About the speakers

Brian Starzomski is the Ian McTaggart Cowan Professor and Director in the School of Environmental Studies at the University of Victoria. He loves to work in a variety of systems to study biodiversity questions, and is broadly trained as a community ecologist and conservation biologist. His research focuses on biodiversity structure and dynamics, and seeks to link theory and empirical approaches. Brian works across the taxonomic spectrum, from insects to plants to birds. He encourages nature lovers to add biodiversity observations to iNaturalist.ca.

Kate McKeown joined the BC Parks iNaturalist Project shortly after graduating with a BSc in Forest Biology from the University of Victoria. Starting on the field team in May 2020, she has since become the project manager. Some of her BC Parks project highlights include finding a brown wasp mantidfly in Skihist Ecological Reserve, photographing Arctic terns in Boya Lake Provincial Park, and seeing peoples’ faces light up when they learn that their passion for wildlife photography can also generate valuable biodiversity data!

Winter observations

From an email by Jocie to the Botany Group on December 24.

Wishing you all a belated happy solstice and a Merry Christmas. A rare white Christmas this year! Between deluges of rain and the current wintery state, botany walks haven’t got off the ground, but I am hopeful that we will get out to look at plants in the coming spring.

In the meantime, there are many winter-interest things to look at for the observant naturalist. I found some nice ice formations a few days ago in Roy Morrison Nature Park, and the snow is great for studying bird and mammal tracks!

A few winter-themed photos [click a photo to enlarge it]:

  1. Ice patterns over sword fern and maple leaves
  1. Hoar frost detail
  1. Icicles on Morrison creek
  1. More icicles on Morrison creek
  1. Raccoon tracks, note raccoons walk with their hind foot beside their fore foot (hind foot on the left, hand-like fore foot on the right)
  1. Deer tracks
  1. My favourite species of Christmas tree: the western white pine (Pinus monticola). So much charm!

More mega polypores, plus bear’s heads

Notes and photos by Alison M. distributed to the Botany Group on November 7.

After the extremely hot dry summer, many of our favourite fungi have been noteworthy by their almost total absence. In Strathcona Provincial Park, both in the Buttle area and up on the Plateau, there have been none of the brightly coloured Cortinarii, nor the Hydnella (e.g. H. peckii – strawberries & cream) and very few amanitas. With the recent heavy rains there are more mushrooms appearing, but for some the optimal period is over for the year, as the temperatures dip and frost and snow start to cover the subalpine.

Here are a few more mega polypores (adding to Jocie’s list in Spectacular polypores) from trails in the Park, as well as a couple of massive bear’s heads. [Click a photo to enlarge it.]

  1. Conifer-base polypore (Heterobasidion occidentale – formerly annosum). This huge polypore was at the base of a dead conifer on the steep flanks of Mt Elma. It differs from the red-belted conk (Fomitopsis mounceae) by being much more bumpy on the upper surface, less regular in outline, often lacking the red/orange band and is found only at the base of dead trees. In spite of its former species name, it can be perennial, as the one in the photo.
  1. Bondarzew’s polypore (Bondarzewia mesenterica – formerly occidentale) on the Elk River trail. (Compare the specimen in Jocie’s photos #8 and #9 in the Spectacular polypores post.) This one measured almost 15 inches across (handle of hiking pole is about 5 inches). It was aging, and the underside could not be photographed in its entirety. The photo of a broken piece shows how the irregular pores become jagged ( almost tooth-like) with age.
  1. Conifer sulfur shelf (Laetiporus conifericola) – another huge aging polypore that has lost its brilliant orange and yellow colour. There were many examples on the Elk River trail of even older specimens which become dull white, and will last over the winter . Broken pieces can be scattered around the original location as a result of critter activity. The second photo shows the bright yellow/orange colour of a younger specimen, from the flanks of Mt. Brooks above Helen Mackenzie Lake.
  1. Greening goat’s foot (Albatrellus ellisii). A largish (6-10 inches wide) ugly specimen that looks like a bolete, but has an irregular-shaped cap, cracked surface, very thick stipe, thick flesh and decurrent wide pores. It stains a blue-green colour when broken, as do some of the boletes, but is overall very tough.
  1. Bear’s heads (Hericium abietis). This fall we have seen several large specimens 20-30 feet up conifers. Here are two dead conifers just off the Elk River Trail. The fruiting bodies of the fungus would be 12-15 inches in diameter and at that height definitely squirrel food. I include two photos from a downed trunk in the Divers Lake area for a closer view.

Learn about mortality of seashore life in the 2021 heatwave

Comox Valley Nature is pleased to co-host the following free online lecture:

Title: Well that stunk: mass die-offs of BC seashore life during the 2021 heatwave
Speaker: Dr. Chris Harley
Date: Sunday, November 21, 2021
Time: 7:00 p.m. PST

This webinar is facilitated by the Canadian Society of Environmental Biologists and is open to the public (see the registration link below).

In late June, 2021, western North America experienced an unprecedented heatwave. A new Canadian all-time high temperature record was set and hundreds of people died. Along the coast of BC, the high temperatures coincided with very low tides, and that combination was lethal for billions of barnacles, mussels, sea stars, and other sea creatures that live in the intertidal zone. Such intense heatwaves, once a 1-in-1000 year occurrence, are expected to become more common and more severe due to climate change.

Dr. Harley will provide an overview of how climate change has already impacted seashore life in British Columbia. He will then describe the impacts of the 2021 heat wave – its geographic extent, the species affected, and the ongoing ecological implications for the northern Strait of Georgia and beyond.

Chris Harley has been studying coastal marine ecosystems along the west coast and around the world for over 25 years. He completed his PhD at the University of Washington in 2001, and spent several years as a postdoctoral fellow at Stanford University and the University of California, Davis. He joined the faculty at the University of British Columbia in 2005, and he is currently joint-appointed in the Department of Zoology and the Institute for Oceans and Fisheries.

Chris and his students are interested in how marine ecosystems are changing and why. They study the ecological impacts of gradual warming, sudden heatwaves, ocean acidification, and changes in salinity. They are especially interested in how biodiversity is changing as a result, and how certain key species can speed up or slow down ecological change driven by human activities. When Chris is especially lucky, his kids come with him down to the shore.
