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.

Klamath Mountains

The Klamath Mountains ecoregion covers much of southwestern Oregon, including the Klamath Mountains, Siskiyou Mountains, the interior valleys and foothills between these and the Cascade Range, and the Rogue and Umpqua river valleys. Several popular and scenic rivers run through the ecoregion, including the Umpqua, Rogue, Illinois, and Applegate rivers. Historically, this ecoregion is known …

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.

Special needs

Found in low gradient streams and rivers including sand- and gravel-substrate glides and pools, backwater sloughs and low velocity riffles. Closely associated with diverse in-water habitat, and are frequently found in and around boulders and instream vegetation.

Limiting factors

Restricted distribution (to Umpqua basin). Passage barriers. Channelization. Wetland drainage. Nonpoint source pollution. Culvert cleaning. Invasive species (predation).

Data gaps

Population dynamics. Abundance estimates and trends. Best management actions in an environment where non-native species are present

Conservation actions

Reduce pollution. Restore flow. Reduce density of invasives in key habitat. Reintroductions useful at some sites. Limit nonpoint source pollution through Total Maximum Daily Load allocation process. Manage nonnative fish predation.
