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.

Herring in the Salish Sea: Webinar Series Feb 22-26

One of the first signs of spring in the Salish Sea is the arrival of spawning herring, and they are almost here! Comox Valley Nature has organized a series of online talks concerning Pacific herring and other fish in the region. There will be one talk each day from Monday February 22 through Friday February 26.

These are free events, but “seating capacity” is limited, and advance registration for each talk is required. After registering, you will receive a confirmation email containing information about joining the webinar.

Note that the start time for each talk is 10:00 am.

Day 1:
Salish Sea Herring 101, Biology Human Use , Status and Management

Monday, February 22, 10:00 am

Speaker: Dr. John Neilson

In this talk, John provides an introduction to Pacific herring, the critical foundation of the Salish Sea marine ecosystem. John discusses its biology, recent human use, and the current status of the resource. He concludes by describing how Pacific herring will become one of the first Canadian fish stocks to be managed using the so-called Precautionary Approach, and what that means for the future.

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.

Bird story: Something unexpected

This story from Bruce Moffat was distributed to the Birding Group on February 2.

I followed 7 Red Crossbills around a Highway 19 rest area for almost an hour, watching their behaviour and following them from tree to tree. It seemed odd to me they would leave the conifer trees laden with cones with the seeds they sought for the bare branches of the maple and alders nearby. They would bend and scrape their bills against the branches, and I presumed were cleaning the bills as many birds do. Upon processing and close examination of the photos (taken with a strong back/sidelight which could not be avoided) I could observe the unexpected. They were drinking. It was these bare branches that were collecting the condensation from the moist air. They lined up the water and did an upside down scrape of the bark to collect the water. Wonders never cease!

Some common winter fungi

This report by Alison M., Some common bright winter / early spring fungi to be found in our forests, was distributed to the Botany Group on January 19.

I picked a few chanterelles and hedgehogs (Hydnum umbilicatum) in our woods on January 1st – unheard of!!!!  Photo #1 shows the latter ready to be cooked. In any of our parks in the Valley, you should be able to find some other bright orange and yellow fungi that are appropriate to the season. 

The jelly type commonly called “witches’ butter” is exemplified by a Dacrymyces species (probably D. palmatus) on conifer (#2), as well as what used to be called Tremella aurantia, now Naematelia aurantia on hardwood (#3). The latter is similar to Gary’s enormous Tremella (sp. = mesenterica?)  circulated at the beginning of the month. Photo #3 shows the Naematelia aurantia with to its right the colourful orange, reddish brown and beige polypore that it parasitizes, namely Stereum hirsutum, which in growth habit is similar to the Turkey Tail or Trametes genus.  Photo #3 of both together was taken in Horne Lake Provincial Park.

Another frequently seen jelly fungus is the one commonly called gumdrops – Guepiniopsis alpina (formerly Heterotextus alpinus) with its little translucent yellow “cups”  attached by a short stalk to dead conifer branches (#4).

Pithya vulgaris is also common at this time of year – it has a small opaque brilliant orange saucer-like body. It is specific to dead branch ends of the Abies grandis (#5 and #6) and is usually very prominent amid the dark browns of dead leaves and fallen branches on the forest floor.

And another January surprise – amid the dark brown seedbearing stalks (# 7) of last year’s Monotropa uniflora (Indian pipe or ghost plant) was a nice little clump of this year’s new shoots (# 8).  And we won’t mention the English daisies and dandelions already in bloom.

The 2020 Bird Photo Challenge

From an email by Bruce Moffat distributed to the Birders Group on January 2.

The CVN Photography Group took up the challenge started by Terry Thormin last year to photograph (web worthy vs. just ID shots) as many bird species as we could in the Valley (including much of the Island). This was done as a challenge where we supported one another rather than a competition. This was further picked up by the Comox Valley Photo Club’s nature group. 

With the year at a close I thought you might enjoy seeing the fruits of this labour, particularly with our wet and dull weather for the next while!

Here are a couple (click a photo to enlarge it):

Below is a link to the full collection of my results, which has individual species galleries. Most species have 4-9 shots each covering males, females, juvi’s, flight, etc…or in some cases just one lonely shot. Click on the species name or photo to enter. When in each gallery click on the photo and it will go full screen. Click on the CVN title to go back to the main collection page. View full screen if you can and go BIG as you can to see the detail.

I ended up passing my goal of 150, then 165, and finally hit my last target of 170 not including the Mandarin Duck and the Myrtle variant of the Yellow-rumped Warbler (was hoping the species would split during the year but it did not).  I also had some Pea Hen shots I did not include, considering them much like other domesticated birds. 

Thanks to those of you who helped locate many interesting birds that came into our area. 

Stay safe, get only a little wet, and hopefully I’ll see you out there at a safe distance until we can get back to high fiving!
