Bull Trout is the most cold-adapted fish in freshwaters of the Pacific Northwest. The species is listed as threatened under the U.S. Endangered Species Act, but climate warming may place the species at further risk. Climate warming may lead to warming of streams in summer and increasing probability of floods in winter, leading to widespread loss of habitat projected for Bull Trout. This project sought to further elaborate how these climate-related threats influence Bull Trout across five western states (OR, WA, ID, MT, NV). These states form the southern margin of the species’ range. We used predictions of temperatures in streams across approximately two-thirds of this extent to map coldwater streams or “patches”...

This update was provided to FWS on March 21, 2013. The assessment incorporates an evaluation of climate and non-climate threats, and potential interactions among them to evaluate potential bull trout persistence. In summary, it includes the following steps: 1) Map suitable habitat "patches" across the species' range in the conterminous United States; 2) Attribute patches with information on local and climate related threats; 3) Map and attribute migratory habitats for the species and their relationship to "patches;" and 4) model persistence of bull trout in relation to local and climate related threats in patches and migratory habitats. For more information, contact Jason Dunham, U.S. Geological Survey, Forest...
