Overview

Species Common Name Klamath Ramshorn
Species Scientific Name Vorticifex klamathensis klamathensis

Ecoregions

East Cascades

The East Cascade ecoregion extends from the Cascade Mountains’ summit east to the warmer, drier high desert and down the length of the state. This ecoregion varies dramatically from its cool, moist border with the West Cascades ecoregion to its dry eastern border, where it meets sagebrush desert landscapes.

Special needs

The Klamath ramshorn is found in spring-influenced streams.

Limiting factors

This species is now restricted to the Upper Klamath area. Habitat loss, including spring alteration and decreased water flow, represents a major threat to the Klamath ramshorn. Sedimentation and nutrient inputs from dredging, mining, road construction, and other land use practices may smother substrates or reduce egg survival.

Data gaps

Assess distribution. Determine species-specific habitat requirements.

Conservation actions

Maintain appropriate water flow and quality. Prevent or mitigate for water diversions, dredging, or other activities that could increase sediment or nutrient levels.
