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

Require cold and clean water, and complex and connected habitats unoccupied by nonnative species.

Limiting factors

Nonnative fish, Degraded upland and riparian habitats. Poor water quality (temperature). Barriers to migration.

Data gaps

Distribution. Abundance. Movement. Long Term monitoring methods.

Conservation actions

Develop long term monitoring strategy. Manage nonnative species. Restore degraded habitats. Improve water quality. Provide passage and prevent entrainment at diversions.
