Like many fishes native to the Rocky Mountains and the Pacific Northwest, bull trout (Salvelinus confluentus) have declined in response to changes in flow regimes, habitat alteration, and invasion of non-native species. Climate change has only exacerbated these conditions and, as a result, the species is now distributed in highly fragmented populations throughout its range. Bull trout may be especially vulnerable to the effects of a warming climate because they need access to large, interconnected habitats of cold water. As such, they are a useful biological indicator of the effects climate change will have on mountain stream ecosystems. For more information: Bull trout and climate change website
