Ecoregions

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

Cool, swift streams. Cobbles and gravel for rearing and spawning.

Limiting factors

Lack of cobble or gravel habitat. Limited distribution. Altered flow regimes (because of culverts, channelization). Altered sediment regimes, including changes in timing of input and ratio of particle size.

Data gaps

Distribution.

Conservation actions

Create and maintain gravel habitat. Maintain or restore flow and sediment regimes to improve habitat quality. Maintain or improve riparian conditions, including habitat for beavers. Foster relationships, partnerships, stewardship, and incentives with partners. Opportunities for research and habitat restoration on Elliott State Research Forest.
