Bull trout (Salvelinus confluentus) are a native char species found in Montana’s cold, clear rivers, streams, and lakes, known for their striking appearance and ecological significance. They are found in the Clark Fork and Flathead drainages of western Montana, and their slowly declining trend has led to their designation as a threatened species under the Endangered Species Act.

Since ESA listing, Montana Fish, Wildlife & Parks has partnered with federal, state, tribal, and provincial agencies, non-governmental organizations, and private companies to implement extensive conservation actions, including suppression of non-native fish, habitat restoration, and acquiring land to protect critical bull trout habitat.
