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.

Coast Range

Oregon's Coast Range, known for its dramatic scenery, is extremely diverse, with habitats ranging from open sandy dunes to lush forests and from tidepools to headwater streams. It follows the coastline and extends east through coastal forest to the border of the Willamette Valley and Klamath Mountains ecoregions

Special needs

Specializes in foraging for invertebrates. Prefers cool, clear streams with coarse sediment.

Limiting factors

Land use practices that reduce riparian cover. Passage barriers. Invasive species that can compete over food resources.

Data gaps

Unknown status and extent of hybridization with cutthroat trout and rainbow trout.

Conservation actions

Maintain riparian cover and other factors that can provide thermal cooling. Reduce localized impacts where populations could become increasingly fragmented.
