Pyrgulopsis aloba
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Pyrgulopsis aloba faces severe threats from groundwater depletion and habitat modification in its limited spring systems. Agricultural water extraction and urban development in the surrounding watershed have reduced spring flow rates, while livestock grazing and recreational activities have degraded the immediate spring environment. The species' extremely restricted range makes it particularly vulnerable to any changes in water chemistry or flow patterns.
Habitat
This freshwater snail is endemic to specific spring systems in the western United States, inhabiting shallow, clear spring pools and associated outflow channels. It requires stable water temperatures, consistent flow rates, and specific water chemistry conditions typical of desert spring ecosystems.
