Juvenile salmon & small streams

The Great Bear Rainforest is home to over 2,500 salmon runs from more than 5,000 spawning populations.  Many of these rivers are still intact, offering a unique opportunity to study the linkages between salmon and the larger food web.

However, salmon in this region are faced with increasing threats, many of which have depressed and extirpated salmon populations throughout the Pacific Northwest. Some of our previous work to understand ecology, status of, and threats to coastal salmon populations is linked below.

Ghost Runs: The status and management of coastal salmon streams

Raincoast has ongoing assessments on the status of BC streams. In 2008, we published Ghost Runs  discussing the status of salmon on BC’s central and north coast. Our findings showed that salmon runs have repeatedly failed to meet their escapement targets as set by Fisheries and Oceans Canada.

Small Stream Surveys

Raincoast has engaged in Small Stream Surveys to document salmon presence in uncatalogued small streams and then expand this to other areas of the central and north coasts of BC.

Chum & Coho Stream Ecology

In partnership with Simon Fraser University, Raincoast examined connections between coho fry and the eggs and carcasses of spawning chum salmon in coastal streams.  This was the focus of the Chum & Coho Stream Ecology Project.

Juvenile Salmon Ecology

In partnership with Simon Fraser University and the University of Victoria, Raincoast examined whether salmon farms situated along the migration routes of juvenile salmon are disrupting survival of sockeye, chum and pink salmon. This was the focus of our Juvenile Salmon Ecology Project.

Monthly giving enables you to protect what you love. For 25 years, Raincoast has been furthering biodiversity conservation in BC. We have big plans and with your help we will: 

  • End commercial trophy hunting of large carnivores in the Great Bear Rainforest.
  • Acquire land in order to protect threatened Coastal Douglas-fir ecosystems.
  • Support the recovery of endangered Southern Resident killer whales by restoring Chinook salmon habitat, and so much more.
