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 Malheur River 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. Northern Basin and Range The Northern Basin and Range ecoregion covers the very large southeastern portion of the state, from Burns south to the Nevada border and from the Christmas Valley east to Idaho. It is largely a high elevation desert-like area dominated by sagebrush communities and habitats. Special needs Requires cool temperatures for spawning and rearing. Requires channel complexity and available migratory corridors. Limiting factors Dams. Water temperature. Brook trout. Riparian habitat. Data gaps Long-term monitoring method. Distribution. Abundance. Conservation actions Address connectivity. Manage effects of brook trout. Increase tree cover to cool streams.
