What is the federal protection status of the bull trout under the ESA in the lower 48 states?
Answer
Threatened
The bull trout holds the federal protection status of Threatened under the U.S. Endangered Species Act (ESA). This official designation covers its historical range within the Columbia and Kootenai River basins, as well as other scattered populations in the lower 48 states. The purpose of this listing is to mandate necessary protective measures for the fish itself and for the critical habitat areas it requires to survive, recognizing that without such interventions, the likelihood of local extirpation or continued population decline increases significantly.
