Viability assessment for Pacific salmon and steelhead listed under the Endangered Species Act: Southwest

The NMFS West Coast Region is responsible for the 5-year review process for Pacific salmon and steelhead and for decision-making regarding any proposed changes in listing status. This report by the Southwest Fisheries Science Center (SWFSC) was completed to provide the West Coast Region (Region) updated information and analyses on the biological viability of the listed ESUs or DPSs, focusing primarily on trends and status in abundance, productivity, spatial structure, and diversity to inform the 5-year reviews of 10 ESA-listed of salmon and steelhead ESUs or DPSs. Where possible, this assessment also summarizes current information with respect to recovery goals identified in recovery plans or Technical Recovery Team viability documents.
