Three Forks Springsnail
Pyrgulopsis trivialis
Overview
The Three Forks springsnail, scientific name Pyrgulopsis trivialis, is a species of very small freshwater snail with a gill and an operculum, an aquatic gastropod mollusk in the family Hydrobiidae. This species is endemic to the United States. The common name is a reference to its endemic range at Three Forks, Arizona.
Pyrgulopsis trivialis faces severe threats from groundwater depletion and habitat modification in its extremely limited range. The species is vulnerable to water diversions, agricultural pumping, and urban development that alter spring flow patterns and water chemistry. Climate change poses an additional threat through increased drought frequency and reduced aquifer recharge in the arid southwestern United States.
Habitat
This freshwater gastropod is endemic to specific spring systems and associated wetland habitats in the southwestern United States. It requires stable groundwater-fed springs with consistent water temperature, flow, and chemistry.
