Pyrgulopsis thermalis
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Pyrgulopsis thermalis faces severe threats from groundwater depletion and habitat modification at its thermal spring locations. Water diversions for agricultural and municipal use have reduced spring flow rates, while recreational activities and infrastructure development around hot springs have degraded water quality and altered natural thermal regimes. The species' extremely limited distribution makes it particularly vulnerable to any changes in spring hydrology or water chemistry.
Habitat
This species is endemic to thermal springs and associated outflow channels in the western United States, requiring specific water temperatures and mineral compositions. It inhabits shallow areas with rocky or sandy substrates where thermal groundwater maintains consistent temperatures year-round.
