Washington Coast Chinook

Summary

The Coast Salmon Partnership convened over 60 experts from tribal, state, and local governments, NGO’s, academia, and more for a Coastal Chinook Symposium in October 2025. This two-day event provided a space for conversation among technical experts about coordinated recovery efforts, and helped us collectively take a broad view on the factors leading to some of the observed declines and the full suite of recovery actions available to us. On the first day (Oct 8th) we laid the foundation for fruitful discussion by inviting 12 experts to share their knowledge about the range-wide ecology of Chinook, and the status and trends in individual watersheds that make up the ESU. On day 2 (Oct 9th) we collectively synthesized the knowledge shared on day 1 to identify key factors to prioritize for future research projects and recovery actions.

Goals

• Identify the state of knowledge about the key factors that explain current status & trends in Chinook in diverse watersheds across the ESU
• Describe key uncertainties, assumptions, or data gaps that are worth resources to investigate because they will improve our ability to manage or recover Chinook
• Identify the full suite of potential actions to address identified data gaps or recovery factors that arise from discussions

Takeaways

The Washington Coast Chinook Symposium convened experts to share the state of knowledge about the primary factors that explain current status & trends among Chinook salmon in diverse watersheds across the range of the Washington Coast ESU. The symposium Summary Report synthesizes the presentations and discussions from the 2-day event and presents six key categories for action to rebuild Washington Coast Chinook. These actions include:

1. Document and Preserve Genetic Diversity of Washington Coast Chinook
2. Reduce Impacts of Pre-Terminal Fisheries
3. Suppress Nonnative Fish Predators
4. Investigate Pinniped Predation and Potential Control Measures
5. Understand and Mitigate for Climate Change Impacts
6. Investigate Changes in Marine Prey Availability and Impacts on Growth

The actions identified through this event fell into a few different categories that highlight the diverse strengths of partnerships within the Washington coast region: political coalition building to share information and advocate for changes to salmon management, studies to improve our understanding of key threats to Chinook salmon survival, and forward-looking adaptation strategies for dealing with climate change-related impacts. As part of these actions, coordination is needed to understand which projects need funding, what data already exist to support proposed projects, what partnerships currently exist, and what coalitions still need to be formed.

The Coast Salmon Partnership is committed to helping rebuild salmon populations across the region, but it will be the engagement of the broader salmon recovery community that moves the needle for Washington Coast Chinook resilience.
