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.

Northern Basin and Range

The Northern Basin and Range ecoregion covers the very large southeastern portion of the state, from Burns south to the Nevada border and from the Christmas Valley east to Idaho. It is largely a high elevation desert-like area dominated by sagebrush communities and habitats.

Special needs

Columbia clubtails are found in river and stream habitats. They lay eggs in the water, and larvae are aquatic.

Limiting factors

Columbia clubtails are endemic to Oregon and Washington. Wetland drainage and river/stream diversion for irrigation and development purposes, storm-water run-off containing pesticides, and carp predation can be harmful to this species. Mosquitofish may present an additional threat when they compete with dragonfly nymphs for small aquatic prey organisms.

Data gaps

Undetermined.

Conservation actions

Protect habitat known to support Columbia clubtails. Manage invasive species in occupied areas.
