  • Species Common Name Klamath Ramshorn
  • Species Scientific Name Vorticifex klamathensis klamathensis


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.

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.
