Ecoregions
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
West Cascades
The West Cascades ecoregion extends from east of the Cascade Mountains summit to the foothills of the Willamette, Umpqua, and Rogue Valleys, and spans the entire length of the state of Oregon. It is largely dominated by conifer forests, moving into alpine parklands and dwarf shrubs at higher elevations.
Willamette Valley
The Willamette Valley ecoregion is bounded on the west by the Coast Range and on the east by the Cascade Range. This long mostly level alluvial plain has some scattered areas of low basalt, and contrasts with productive farmland and large urban areas. It has the fastest-growing human population in the state resulting in challenges due to land-use changes.
Special needs
Require streams with clean gravel, complex habitat, and cool temperatures for spawning and rearing. Require access for anadromous migration.
Limiting factors
Water quality. Alterations of hydrology and watershed function. Fish passage. Riparian condition. Marine survival.
Data gaps
Continue ongoing monitoring of populations and conservation effectiveness.
Conservation actions
Maintain or restore aquatic and riparian habitat. Continue ongoing restoration efforts involving landowners, tribes, and agency partners (NOAA, NMFS, ODFW, OWEB).
