Summary

This project aims to integrate new and existing data with expert opinion in a decision support model for assessing contemporary threats and climate vulnerability for threatened bull trout (Salvelinus confluentus) across the species’ contemporary range in the conterminous United States. Results will include a  synthesis document outlining key considerations for developing a climate vulnerability assessment, and the assessment itself, which will include the following: 1) new spatial data and maps of the current distribution of bull trout, their habitats, and threats to these habitats, 2) a synthesis of the most recently available scientific information and expert opinion, and 3) a linked decision support tool (Bayesian network). The assessment will represent a complementary extension of existing efforts to address climate impacts on inland trout and salmon and the coldwater ecosystems they depend on in the western US.
