Special needs

The lined ramshorn is found in spring-fed lakes and large creeks.

Limiting factors

This species has a very restricted distribution. Habitat loss, including spring alteration and decreased water flow, represents a major threat to the lined 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.
