Feasibility Assessment of Sea Otter Reintroduction to the Pacific Coast

The U.S. Fish and Wildlife Service was directed by Congress to look at the feasibility and cost of reintroducing sea otters on the Pacific Coast, including Oregon, Washington, and California. This directive stemmed from language that was included in the Consolidated Appropriations Act for 2021, Sea otters have been absent from most of the Pacific Coast for more than 100 years, since their near extinction as a result of the maritime fur trade. 

This Feasibility Assessment of Sea Otter Reintroduction to the Pacific Coast (Assessment) constitutes our report to Congress.
