Raincoast research

We found that when black bears have access to four salmon species, they consume ~3x more salmon each year (Figure A)... than they do when there is one big run of equal biomass comprised of only one salmon species (Figure B).

Bear-salmon interactions: species diversity matters (infographic)

Managing salmon for wildlife typically focuses on providing enough biomass, a measurement of the total kilograms of spawning salmon available. We asked whether biomass-and the number of salmon species-might affect salmon consumption by black bears in coastal BC, a measure that strongly relates to population productivity and health. Biomass actually did not matter to salmon …

Dozens of Chum

Caught our first juvenile salmon of the season this weekend! We found dozens of these little chum salmon fry in the North Arm of the Lower Fraser River yesterday, the first juvenile salmon of the season to migrate downstream into the estuary where they likely spend a few days or weeks before moving on to …

International Women’s Day

From the original Raincoast scientist – Misty MacDuffy – to the majority of our lab team @universityofvictoria and board members – Maureen Gordon and JJ Woodland – women continue to play a leading role in every aspect of our work. Science and conservation certainly have room for more gender balance.

National Energy Board Approval of Trans Mountain Proposal

Today’s recommendation by the National Energy Board for approval of the Trans Mountain tanker and pipeline proposal was no surprise. Unfortunately no mitigation measures can protect the Southern Residents from the noise of the increased tanker traffic. The Canadian government have already bought the pipeline. If the cost also includes the extinction of the Southern …

Biodiversity matters: diversity of salmon species is more important to black bears than simply the total amount of salmon

Biodiversity matters.  New research published today by Raincoast, Spirit Bear Research Foundation and The University of Victoria shows that the diversity of salmon species is more important to black bears than simply the total amount of salmon available.  This is further evidence that maintaining salmon species diversity is key to ensuring terrestrial wildlife – like black bears …

Researchers on in Gitga’at, Heiltsuk, Kitasoo/Xai’xais, Nuxalk and Wuikinuxv territories.

Gitga’at, Heiltsuk, Kitasoo/Xai’xais, Nuxalk and Wuikinuxv territories

Over the coming weeks Raincoast scientists will join friends and colleagues in Gitga’at, Heiltsuk, Kitasoo/Xai’xais, Nuxalk and Wuikinuxv territories. With the Central Coast First Nations Bear Working Group we monitor bears in area of more than 22,000 square kilometres. This long-term monitoring of grizzly and black bears combines traditional ecological knowledge with cutting edge science …
