Elimia porrecta
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Elimia porrecta faces severe threats from water pollution and sedimentation in its limited freshwater habitats throughout the southeastern United States. Dam construction and river channelization have significantly altered natural flow regimes, disrupting the species' reproductive cycles and feeding patterns. Agricultural runoff containing fertilizers and pesticides has degraded water quality in many streams where this freshwater snail historically occurred, leading to population declines and local extirpations.
Habitat
Elimia porrecta inhabits clean, well-oxygenated freshwater streams and rivers with rocky or gravel substrates in the southeastern United States. The species requires stable water flow and specific water chemistry conditions, typically found in spring-fed streams and headwater tributaries with minimal human disturbance.
