Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

The Flat Pebblesnail faces severe threats from water pollution and sedimentation in its limited freshwater habitats throughout the southeastern United States. Dam construction and water diversions have altered natural flow regimes, while agricultural runoff and urban development introduce harmful chemicals and excess nutrients that degrade water quality. The species' restricted range and specialized habitat requirements make populations particularly vulnerable to local environmental changes.
