Pyrgulopsis bacchus

Unknown

Overview

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

Pyrgulopsis bacchus 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 habitat through trampling and sedimentation. The species' extremely restricted range makes it particularly vulnerable to any changes in water chemistry or flow patterns.

Threat summary

Habitat

This freshwater gastropod is endemic to specific spring systems in the Great Basin region, inhabiting shallow, clear spring pools and associated outflow channels with stable temperatures and mineral-rich waters. The species requires pristine spring environments with consistent flow rates and specific water chemistry conditions.
