Physella utahensis

Unknown

Overview

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

Physella utahensis faces severe threats from habitat modification and water quality degradation in Utah's freshwater systems. Urban development and agricultural runoff have altered the natural flow regimes and water chemistry of springs and streams where this endemic snail occurs. Introduced species, particularly non-native fish and other mollusks, compete for resources and may prey upon juvenile snails, further reducing population stability.
