Bull Trout & Climate Change                       Back to the Climate Change Resource Center


Bull trout (Salvelinus confluentus) are a threatened fish species with a highly fragmented distribution throughout the Pacific Northwest. Among the critical requirements for bull trout are a need for large, interconnected habitats of cold water. While the needs of bull trout for cold water and ongoing restoration actions are well known and being addressed, much uncertainty remains about the future security of bull trout and their habitats within the US due to environmental trends associated with climate change. The goal of this symposium is to provide an overview of bull trout, their relationship to climate, and to discus alternatives for modeling future habitat and population distributions.
