Oregon Chub – State Wildlife Action Plan

Overview

Species Common Name Oregon Chub
Species Scientific Name Oregonichthys crameri
State Listing Status Sensitive

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

Off-channel habitat, backwater sloughs, ponds, and low gradient streams.

Limiting factors

Predation by and competition with invasive species. Passage barriers. Channelization. Nonpoint source pollution. Drainage of key off-channel habitat.

Data gaps

Impacts of non-native species. Relationship between flow management and population fitness.

Conservation actions

Implement invasive species removal programs. Remove passage barriers or mitigate for effects. Reduce pollution. Restore floodplain processes.
