Overview

Species Common Name A Stonefly (no common name)
Species Scientific Name Capnia kersti

Ecoregions

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

These stoneflies are associated with seasonally-dry, low-elevation stream beds. This species is currently known only to an approximately 0.25-mile stretch of a single stream on the West Fork of Willow Creek (near Eugene, OR).

Limiting factors

This species has a severely restricted distribution.

Data gaps

Conduct surveys to determine potential distribution at additional locations.

Conservation actions

Protect existing habitat. Identify any additional occupied sites.
