Pacific salmon are ‘foundation’ species. This is different from the more familiar term keystone species. A keystone species has an influence on its environment that is disproportionate to its abundance. Like the keystone in a masonry arch, its removal can have a strong effect on the surrounding community. In the Pacific northwest, species like sea stars, sea otters, and wolves are considered keystone species.
A foundation species, on the other hand, is important because of the role it plays due to its sheer biomass in the ecosystem, and the strong influence this has on structuring a community. Foundation species support ecosystem structure, process and organisms from the bottom up. Foundation species can be plants or animals with many species relying on them, but not disproportionately to their abundance, it’s because of their abundance. On the Pacific Northwest coast, the collective group of salmon species (chum, pink, etc), herring, and giant kelp are examples of foundation species.
Raincoast’s Wild Salmon Program is focused on ensuring that BC’s 450+ unique and irreplaceable Conservation Units of wild salmon persist over their historic range at spawner abundance levels suitable to meet the needs of wildlife and ecosystems. Conservation Units consist of thousands of spawning populations from hundreds of coastal rivers and watersheds across BC.
BC salmon face multiple obstacles. Domestic and international harvest, habitat loss (including watershed development), interactions with hatchery and cultured salmon and climate change can individually and cumulatively reduce the abundance of spawning salmon. We address these issues through academic, community, policy and on-the-ground initiatives.
Raincoast’s wild salmon initiatives are the product of coordinated strategies between diverse groups including First Nations, coastal communities, academic institutions (such as UVic, UBC and SFU) and other NGOs. Our policy recommendations and advocacy on behalf of salmon conservation and wildlife are informed by our research.

Salmon declines could have long-term effects on grizzly bear health, conclude authors of a study published today in the scientific journal PLOS ONE. The researchers examined stress and reproductive hormones of salmon-eating grizzly bears from coastal British Columbia. Their results,…

The purpose of this pilot study was to investigate whether it is feasible to undertake a large-scale juvenile salmon migration mapping project on the central coast. View the report in .PDF
This report describes the role of small salmon runs in the overall structure and genetics of salmon populations. It is a response to the increased effort of federal monitoring of large salmon-bearing streams, at the expense and health of small…
Raincoast’s Small Stream Surveys document the existence of hundreds of small streams that support salmon, yet are not catalogued federally or provincially.
In partnership with SFU, the Chum & Coho Stream Ecology project found that juvenile coho abundance is up to 3x higher in streams that have pink and chum runs compared to streams that don’t.
In partnership with SFU and the UVic, the Juvenile Salmon Ecology Project found that salmon farms on the migration routes of juvenile salmon disrupt survival of sockeye, chum and pink salmon.
