CVN birders and the MARS connection

This report was prepared by Royann Petrell and Kelly Kline.

In 2020, the CVN Birders Group established a partnership with the Mountainaire Avian Rescue Society (MARS) to enhance the bird displays at their visitor centre. Last spring, Art Martell gave two presentations on the topic of the Trumpeter Swans to packed audiences at the visitor centre. Bruce Moffat was to give a photo essay on the story of a baby Loon. This will be rescheduled when the pandemic is over.

Establishing wetland plants

Royann Petrell provides an update in the photos below on a landscaping project at MARS to establish bird-friendly plants [click a photo to enlarge it]. She began planning a year ago and now is having weekly work parties with Karen Cummins and Jan Smith. More volunteers are needed for planting. Royann will provide training and education.

Birding volunteers needed

We would like weekly bird observations at MARS as we will compare species abundance before and after replanting.  Linda, Gord, Kathyrn, and Krista have been doing this, but they will need more birders to have weekly reports. To date, 73 species have been recorded on eBird, and approximately half that on iNaturalist.

If you would like to help with either the planting or bird counting, please contact Royann, or email Kelly at cvnbirds [at] gmail [dot] com and he will put you in touch.

Big trees close to home

From an email by Jocie to the Botany Group on March 1.

While going through some books I came across a copy of Randy Stoltman’s classic Hiking Guide to the Big Trees of Southwestern British Columbia from the early 1990s. Stoltman was an advocate for BC’s forests and the protection of old growth, and he started BC’s big tree registry, which is now managed by UBC. Tragically, Stoltman lost his life while on a ski trip in 1994.

The current registry includes a list of “champion trees,” which are the largest trees of each species determined by a score based on height, diameter and crown. The registry also has listings of many additional big trees, and anyone can nominate a tree. Unfortunately, the registry does not mean that any of these trees are protected. You can check out the registry here.

I had big trees on my mind while taking a walk in Miracle Beach Provincial Park on the weekend. I got the kids involved, and we identified the 5 largest Douglas-firs in the park. Some of these rare old growth firs escaped logging, and also the devastating fire of 1938 which swept through much of the Black Creek and Merville area. [See photos at right and below.]

Just for fun, we measured the DBH (diameter breast height) of each of these top 5 and the winner was the large fir that stands right at the campground entrance, at 2.06 metres. Interestingly, there is a fir in Kitty Coleman Provincial Park in the big tree registry that is 2.75 metres. The largest Douglas fir in BC is the Red Creek fir in the Port Renfrew area, with a whopping DBH of 4.23 metres.

 Looking at things from an arboreal perspective, it hits home just how much old growth forest we have lost and continue to lose on Vancouver Island. Photographer TJ Watt captured some before and after images of logging in the Caycuse watershed in 2020 which have received international attention. Here is an article about it in the Narwahl, This is just one example of what is happening to the last remnants of old growth forest. Around 9000-10,000 hectares of old growth forest continue to be logged each year on Vancouver Island, and many of the big trees chronicled in Stoltman’s book are long gone.

The Ancient Forest Alliance  and Western Wilderness Committee  are good sources of information on what’s really going on in the woods, and how one can take action. The AFA also has some inspiring short videos here.

Here are a few more photos of the big trees of Miracle Beach Park. Though they aren’t going to be contenders as “champions” they are certainly impressive in their own right! [Click a photo to enlarge it.]

What’s blooming now?

From an email by Jocie to the Botany Group on March 6.

Well, it is only early March, but a few tiny (and mostly weedy) species are already in bloom, shivering in the cold wind.

Here are a few things from Kin Beach Park in Comox [click a photo to enlarge it]. There should be some more early bloomers (blue-eyed Mary and such) coming along soon.

Helen reports that there are no gold stars (Crocidium multicaule) in bloom at Point Holmes yet, where they usually appear. The earliest blooming gold stars that Helen has on record are from February 22.

  1. The diminutive common whitlow-grass (Draba verna) is one of the first spring blooms. Note the seed capsules (silicles) at the top of the photo.
  1. Chickweed (Stellaria media), a commonplace garden weed, but good in salads if you have enough of it.
  1. Red deadnettle (Lamium purpureum). This small member of the mint family is edible, and tastes like spinach though the leaves are a bit hairy.
  1. Bittercress sp. in the genus Cardamine. I didn’t look too closely at it, but likely it is C. oliogosperma or C. hirsuta. C. oligosperma is a rhizomatous perennial, whereas C. hirsuta is a taprooted annual with hairier leaves. According to iNaturalist, C. hirsuta is more common in our area. It’s good tossed in a salad, and the taste has a nice peppery kick, as expected from a member of the mustard family.
  1. The English daisy (Bellis perennis). Not native to these parts, but a charming addition to the lawn where, thankfully, it usually stays.
  1. Miner’s lettuce (Claytonia perfoliata), though not in bloom yet, the new green leaves huddling under the firs are a welcome sight. A nice lettuce-like edible, but don’t tell anyone, since the remaining habitat for this plant is scarce. Keep your sampling minimal!

Nominate a tree for the 2021 CVN Tree of the Year

This year, CVN’s Tree of the Year contest is being held in honour of Cathy Storey, the member whose initiative founded this activity. Cathy passed away in December 2020.

In this fourth year of the contest, we have made several improvements:

  • 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 now and April 1. Visit our Tree of the Year page to learn more about the contest and to access the nomination form.

After nominations close, we will prepare cycling and walking guides to suggest routes by which you can visit these trees, and make the guides available on this website.

Voting will open April 16 and run until June 1. Watch for additional details at that time.

Learn about exploring data on Pacific salmon

Comox Valley Nature is pleased to host a free online lecture by Dr. Eric Hertz. The lecture entitled “The Pacific Salmon Explorer: A novel tool for mobilizing data on salmon and their habitats.” is on Sunday March 21, 2021, 7:00 pm PT and is open to the public (see the registration link below).

Salmon are critical species in British Columbia, but understanding their status is hampered by limited access to data. The Pacific Salmon Explorer is a novel tool that democratizes salmon data, with many potential uses (www.salmonexplorer.ca). This tool provides access to the best available data for salmon conservation units (CUs) in BC. Applying a standardized assessment approach, the Pacific Salmon Foundation (PSF) evaluates the current status of salmon CUs and pressures on their habitats. The Pacific Salmon Explorer is a living tool, and the information and analyses are updated regularly as new data become available.

Eric Hertz is an Analyst with the Pacific Salmon Foundation – Salmon Watersheds Program, where he leads the data compilation and synthesis efforts to understand the status of salmon populations across British Columbia. Prior to joining the Pacific Salmon Foundation, Eric received his Ph.D. from the University of Victoria in 2016, where he studied the early marine ecology of juvenile Chinook salmon. Following this, he was a Postdoctoral Fellow at Simon Fraser University, where he worked on a collaborative project with the Heiltsuk, Kitasoo/Xai’xais, Nuxalk, and Wuikinuxv First Nations to better understand spatial and temporal changes in the abundance of salmon in their territories.

Given the current situation with the COVID-19 pandemic, Comox Valley Nature has made arrangements to have a live, online webinar for the presentation. You will need to register in advance. Check the system requirements for attendees here.

Day 3:
Assessing Seabird Ecological Correlates to Inform Conservation

Wednesday, February 24, 10:00 am

Speaker: Dr. Ignacio Vilchis

Seabirds are known indicators of ecosystem status and change in marine environments. This is because most marine birds are long-lived, migratory, and at upper levels of food webs and therefore ideal indicators of changing productivity and ecosystem structure across broad spatial and temporal scales. In addition, marine birds are highly visible in habitats where most other animals are underwater, making them much more accessible to count than other marine life.

In this seminar Dr. Vilchis will argue that marine monitoring programs assessing ecosystem-wide trends in biodiversity and abundance of entire communities can reveal important clues about the commonalities of species that are more likely to stop frequenting an ecosystem. And that this is particularly true for seabirds, as syntheses of long-term trends in a marine predator community will not only provide unique insights into the types of species that are at risk of extirpation and why, but can also inform conservation measures to counteract threats—information that is paramount for species-specific and ecosystem-wide conservation.

Day 4:
Rebuilding Fisheries: Unlocking Canada’s Potential for Abundant Oceans

Thursday, February 25, 10:00 am

Speaker: Dr. Robert Rangeley

Healthy fish populations are critical to healthy ecosystems and coastal communities. Our oceans are facing growing threats and greater uncertainty, putting the marine life we all depend upon at risk. Bob will summarize the current state of Canada’s fisheries and fisheries management recommendations for restoring abundance to our oceans.

Register for Day 4

Day 5:
Salish Sea Archaeology of Herring

Friday, February 26, 10:00 am

Speaker: Dr. Iain McKechnie

For many Indigenous peoples, the right and ability to fish is inseparably linked to their history, social relations, economy, and physical well-being. In British Columbia, salmon are iconic and have greatly enriched perspectives on the importance and antiquity of these fish for people’s livelihoods and life on the coast. However, in archaeology, an emphasis on salmon has received much attention relative to other species, particularly as small fish such as herring, anchovies, and smelts tend to not be as readily recovered during excavation and screening.

In this presentation, Dr. McKechnie describes zooarchaeological fisheries records from over 222 heritage sites from Alaska, British Columbia, and Washington to provide measures of Indigenous fisheries catches spanning the past several millennia. In particular, he observes that herring (not salmon) are the most common and abundant fish in the majority of zooarchaeological assemblages (NISP) but particularly in the Salish Sea. He advocates for consideration of archaeological datasets for contemporary management and harvesting plans and for considering restoring the past abundance and former spawning locations of herring.

Learn about genetic risks of hatchery enhancement for Pacific salmon

Comox Valley Nature is pleased to host a free online lecture by Dr. Carrie Holt. The lecture entitled “Genetic risks of hatchery enhancement for Pacific salmon.” is on Sunday February 21, 2021, 7:00 pm PT and is open to the public (see the registration link below).

Under Canada’s Wild Salmon Policy, the conservation of wild salmon and their habitat is the highest priority in the management of Pacific salmon. Hatchery production is used as a conservation tool for wild populations by DFO’s Salmon Enhancement Program and can increase the availability of fish for harvest, but is a risk factor to wild genetic diversity. This risk requires management and mitigation to safeguard Pacific salmon biodiversity.

In this presentation, Dr. Carrie Holt will describe these genetic risks and outline a proposed approach for classifying populations that reflects the adaptive state of the population based on proportions of natural- and hatchery-origin fish. She will further explore approaches for minimizing genetic risks of enhancement to wild populations. Except for populations near extirpation, limiting hatchery size by scaling the hatchery program to natural production is an effective way to reduce these risks. Limiting hatchery program size also limits the production of fish for harvest, resulting in a trade-off between genetic risk and socioeconomic benefits in enhancement programs implemented for harvest augmentation.

Carrie Holt is a Research Scientist with Fisheries and Ocean Canada at the Pacific Biological Station in Nanaimo, BC.  She was raised in Toronto where she completed her MSc in limnology on the recovery of lakes from acid damage from acid rain. She found her way to the ocean for her PhD on the management and ecology of Pacific salmon at Simon Fraser University in the School for Resource and Environmental Management. She draws from her multi-disciplinary background in ecology, mathematics, and resource management in her current work evaluating assessment methods for Pacific salmon using quantitative models of population dynamics. She has also applied those models to evaluate genetic impacts of hatcheries on salmon that spawn in the natural environment.

Given the current situation with the COVID-19 pandemic, Comox Valley Nature has made arrangements to have a live, online webinar for the presentation. You will need to register in advance. Check the system requirements for attendees here.
