Do you have a bat box?

This article about a Canada-wide community science project is contributed to our website (and other outlets) by Karen Vanderwolf, a PhD student at Trent University and Research Associate at New Brunswick Museum. A more detailed article will appear in CVN’s November newsletter.

If you have a bat box, scientists want to know about it!

Bats in Canada face multiple threats from habitat loss and disease. A bat box is a simple way to provide additional roosting habitat for bats, yet little is known about bat box use in Canada. Information on bat box use is especially important as three bat species in Canada are listed as endangered: little brown bats, northern long-eared bats, and tricolored bats.

If you have a bat box and would like to participate in this study, please fill out this online multiple-choice survey with questions about your bat box. Your participation is important even if your box does not have any bats!

This project is in partnership with the Wildlife Conservation Society and the Canadian Wildlife Federation. More information on the project is posted here and here.

Learn about chemical contaminants in our oceans

The Canadian Society of Environmental Biologists is hosting a free online lecture as follows:

Title: Environmental pollution in British Columbia: A short history of chemical conquest
Speaker: Dr. Peter Ross
Date: Sunday, October 17, 2021
Time: 7:00 p.m. PT

This talk is open to CVN members and the public (see the registration link below).

Canada enjoys the longest coastline in the world, with 229,000 km spanning three oceans. This raises fundamental questions about how best to understand, let alone protect, marine biota from the complex blend of chemicals used, lost, or disposed of, in consumer or industry activities. With an estimated 500,000 chemicals on the market, this is a daunting challenge for scientists, regulators and resource managers.

Considering that 80% of ocean pollutants originate from land, the generation of data that helps us track contaminants back to their source will underpin solution initiatives. The Raincoast Conservation Foundation is now launching a new community-oriented water pollution program – Healthy Waters – that will track priority pollutants from land to sea. This will address a gap in regulatory and jurisdictional boundaries, and enable Indigenous Nations and communities to better manage pollutants within their area of interest and beyond.

Dr. Ross will provide a short history of pollution in British Columbia, and present examples of topical concerns including hydrocarbons, PCBs and microplastics, all under the mantra of healthy salmon, whales and people.

Dr. Peter S. Ross is a Senior Scientist at Raincoast Conservation Foundation in British Columbia, where he is launching a new initiative: the Healthy Waters Program.

He is an internationally recognized ocean pollution expert, having published over 160 scientific articles and book chapters on the fate and effects of a variety of pollutants of concern in the world’s oceans. He is a frequent advisor to conservation teams in different parts of the world, and has provided advice in support of chemical regulation, species at risk, ocean disposal and ocean health. He has long valued his partnerships with Indigenous communities working in support of safe traditional seafoods.

Dr. Ross is an Adjunct Professor at UBC Department of Earth, Ocean and Atmospheric Sciences, and at the UVic School for Environmental Studies. He recently served as the Vice-President of Research at Ocean Wise, where he founded the Ocean Pollution Research Program, launched PollutionTracker and the Plastics Lab, a dedicated high resolution facility working with industry, government agencies and academia on microplastic pollution. Prior to that, he served for 16 years as a federal Research Scientist with Fisheries and Oceans Canada. His work with priority pollutants and microplastics has led to numerous invitations to advise industry, government, the G7, the European Union, and the OECD.

Bedwell and Cream Lakes botany (part 1)

From an email by Jocie to the Botany Group on September 4.

Apart from Alison’s lovely photos of Paradise Meadows, we haven’t delved into subalpine/alpine plants much this summer. So, here is a blast of the mountain flora.

I went backpacking with my kids to Bedwell and Cream Lakes in Strathcona Park from August 18–20th. We camped at Baby Bedwell and did a day hike to Cream Lake. I hadn’t done this hike for quite a few years, and in my mind the terrain was more level and easy (funny how that is). It was a rough, rocky uphill slog! In short, my kids have vowed to never backpack again, but I think they will get over it.

Despite the dry summer the Cream Lake area was full of lush blooms. It’s an area that has late-lingering snow and seems to have quite a lot of water. Even the blueberries were plump. We were lucky to see an enormous black bear plowing through the berries (a slight trail detour but no big deal).

Here are some of the plants and views (part 1). Click a photo to enlarge it. More to come in a second instalment.

  1. View of Bedwell Lake and Mt. Tom Taylor
  1. Lewis’ monkey-flower (Erythranthe lewisii)
  1. White pasqueflower, or “tow-headed baby” (Pulsatilla occidentalis)
  1. Olympic aster (Eucephalus paucicaptitatus)
  1. Western sweetvetch (Hedysarum occidentale)
  1. Alpine sorrel (Oxyria digyna)
  1. Mt Septimus view, with western columbine (Aquilegia formosa), cow parsnip (Heracleum lanatum), and harebell (Campanula rotundifolia)

Lakeside plants, old boots, and other things

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

I don’t know how you all coped with the excessive heat this summer…but I ended up spending more time out on the water than I did hiking. I paddled some parts of the Sayward Canoe route, which is a chain of lakes northwest of Campbell River.

The timber around these lakes has been logged in the past and logging is ongoing. Though the area is mostly unprotected, much of the lake flora remains intact and I imagine it is quite similar to what it would have been like pre-logging. Despite the ongoing abuses to this area, these lakes have a quiet, peaceful character and some lovely native plants, a few of which I’ll share here. These are from Amor Lake. [Click a photo to enlarge it.]

  1. King gentian (Gentiana sceptrum). Alison recently sent a photo of this lovely blue flower from Paradise Meadows, but gentians can also be found along the edges of lower elevations lakes.
  1. Northern water horehound (Lycopus uniflorus). This member of the mint family has tiny white flowers in the axils, but it lacks a mint scent.
  1. Field mint (Mentha arvensis). This mint, with clusters of lilac-coloured blooms in the axils, has a strong minty odour and makes a nice tea.
  1. Aster….so many asters but this is likely Douglas’ aster (Aster douglasii) though I didn’t look at it very closely.
  1. Lake shores glisten with red-coloured sundews, whose sticky leaves trap insects. This is a patch of great sundew (Drosera anglica).
  1. Lake reflections to contemplate from the canoe.
  1. Here’s a creature that isn’t celebrated much…a leech (subclass Hirudinae) that was lurking in the shallows. It had some quite handsome black & brown speckling. It didn’t stop me from having a swim!
  1. Lots of dragonflies on the lakes. According to “Dragonflies of BC & the Yukon” (Cannings) this looks like the saffron-winged meadowhawk, Sympetrum costiferum (note the golden veins on the wing).
  1. Resting the Grumman (built like a tank and almost as heavy) on a short portage from Amor Lake to Surprise Lake. There’s a camping spot here known as “Mr. Canoehead” which has a nice display of old historic logging boots and various shoes.

Learn about notable flora of Strathcona Park

Comox Valley Nature members and the general public are invited to attend the following free online lecture presented by the Strathcona Wilderness Institute:

Title: Notable Flora of Strathcona Park
Speaker: Eva Ullstrom
Date: Sunday, September 12, 2021
Time: 7:00 p.m. PDT

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

The vascular plants of Strathcona Provincial Park have long been the centre of floristic surveys and botanizing excursions. Despite Strathcona Park being subject to floristic surveys since the 1880s and now having many popular backcountry trails, the gaps in understanding species occurrences and distribution are still large. Biodiversity surveys across Strathcona Park this past summer revealed some of the lesser-known flora species of the park. Ranging from species never recorded in the park to unexpected oddities, Eva will present some of these notable flora and why they stand out from the 300+ species of vascular plants observed this summer.

Eva Ullstrom is one of the summer students engaged as research assistants by Strathcona Wilderness Institute through the Canada Summer Jobs program this year. The students have now completed their work out on the trails in the Park documenting flora and fauna for the SWI Data Collection project on iNaturalist. Their last assignment is to deliver a webinar to the public on a project of their choice.

“Seating capacity” for the talk is limited, and you will need to register in advance. You can check the computer requirements for attendees here.
