Pleurocera walkeri

Unknown

Overview

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

Pleurocera walkeri faces severe population declines primarily due to water pollution from agricultural runoff and urban development within its limited Tennessee River system range. Dam construction and river channelization have fragmented populations and altered the fast-flowing, rocky substrates essential for this species' survival. Sedimentation from erosion has degraded water quality and buried the clean gravel beds where these freshwater snails feed and reproduce.

Threat summary

Habitat

This freshwater gastropod inhabits fast-flowing, well-oxygenated streams and rivers with rocky or gravel substrates in the Tennessee River drainage system. The species requires clean water with minimal sedimentation and stable flow regimes to maintain the algae and detritus it feeds upon.
