Bull Trout, Umatilla SMU Photo Credit: Terry Smith, U. S. Forest Service Overview Species Common Name Bull Trout Species Scientific Name Salvelinus confluentus Federal Listing Status Threatened State Listing Status Sensitive SMU/ESU/DPS/Subspecies Umatilla SMU Ecoregions Blue Mountains Located in NE Oregon, the Blue Mountains ecoregion is the largest ecoregion in the state. It provides a diverse complex of mountain ranges, valleys, and plateaus that extend beyond Oregon into the states of Idaho and Washington. Columbia Plateau The Columbia Plateau ecoregion was shaped by cataclysmic floods and large deposits of wind-borne silt and sand earlier in its geological history. It is dominated by a rolling landscape of arid lowlands dissected by several important rivers, and extends from the eastern slopes of the Cascades Mountains, south and east from the Columbia River to the Blue Mountains. Special needs Requires cool temperatures for spawning and rearing. Requires channel complexity and available migratory corridors. Limiting factors Passage barriers. Habitat. Data gaps Long-term monitoring method. Conservation actions Continue habitat restoration. Screening.
