Learn about the benefits of Garry oak ecosystems

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

Title: Garry Oak Ecosystems – Benefits to Urban Areas
Speaker: Thomas Munson
Date: Sunday, February 20, 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).

Less than 5% of the rare Garry oak ecosystems exist in their natural form on Vancouver Island. Despite their rarity, they perform valuable ecological, cultural and economic functions in our urban areas. Protecting and managing Garry oak ecosystems in these urban areas is a challenge, for many reasons. Examples of successful management will be discussed from urban areas in Victoria and Saanich. These examples could be beneficial if applied to the northern range of Garry oak ecosystems in the Comox Valley.

About the speaker

Thomas Munson holds a Bachelor of Environmental Studies degree from University of Waterloo, and a Restoration of Natural Systems Diploma and Masters of Science degree from the University of Victoria. He has worked with First Nations in Yukon Territory, British Columbia, and Colombia, South America for much of the past 20 years. Thomas worked as Environmental Technician for City of Victoria Parks, in restoration, and management of Garry oak ecosystems. Now, as Senior Environmental Planner for District of Saanich, he works to protect these same ecosystems from development activities.

Cooley spruce gall

From an email by Jocie to the Botany Group on January 30.

Fanciful-looking Cooley spruce galls add a splash of colour to these grey, dreary days. Many have funky shades of purple, red and yellow. They vary depending on what stage they are at— older galls are dull brown.

I’ve been noticing just how abundant these galls are on the branch tips of local Sitka spruce wherever I go. I’ve also seen plenty up the mountain on the Engelmann spruce that’s been planted along the Jutland ski trail. See some photos below (click a photo to enlarge it).

The galls are caused by a tiny aphid, Adelgid cooleyi, with a complex life history (6 generations! – see the diagram below). Interestingly, the aphid requires more than one conifer species to complete its life cycle. For this species, the alternative host is usually Douglas fir (it’s called the Douglas-fir adelgid on iNaturalist). The adults look like tiny dots of white wool (see the reference below for photos). I haven’t seen these on Douglas fir needles before but it’s something to look out for!

I confess that I know nothing about spruce galls, but they are interesting to look at on a dull winter day! To learn everything you might ever want to know about them, you can download this document from the Forest Genetics Council of B.C. It’s worth looking at just to see all the great photos of different stages.

If any of you are spruce gall experts, or have anything to add to this discussion let me know.

Gorse and broom a source of protein?

From an email by Jocie to the Botany Group on January 29.

An article from the Guardian, here, tells how gorse and broom could potentially be used as a source of protein. Maybe we should be using more invasives as a food source! Thanks to Mandy for sending this. [But note the caution about toxicity below the photos.]

These invasive shrubs (I’m sure you are all well familiar with them) are both in the pea family. Here are a few photos of local examples [click a photo to enlarge it].

  1. Scotch broom (Cytisus scoparius): leaf and seed pod detail (from Piercy Rd. wasteland near the inland highway).
  1. Gorse (Ulex europaeus): in bloom last December at Woodhus Slough.

Notes on the toxicity of these plants from a follow-up email by Jocie:

Please don’t go out and eat these plants, as they can be toxic to humans and livestock! The article mentioned “isolating the protein to make it safe for consumption” which must involve removing the toxic alkaloids.

Gary S. sent me an email which raises some good points about this:

“I was surprised that the article does not deal with the known toxicity of Scotch broom to humans and livestock. There is a documented history of poisoning in British Columbia beginning with the use of broom for brewing tea by Chinese labourers building the railroad.”

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!
