Pyrgulopsis gilae

Unknown

Overview

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

Pyrgulopsis gilae faces severe threats from groundwater depletion and habitat modification in its limited spring systems within the Gila River basin. Agricultural water extraction and urban development have reduced spring flow rates, while livestock grazing and recreational activities have degraded the delicate aquatic vegetation communities these snails depend upon. Climate change compounds these pressures by increasing evaporation rates and reducing groundwater recharge in the already arid southwestern United States.

Threat summary

Habitat

This freshwater gastropod is endemic to spring-fed pools and slow-flowing spring runs in the Gila River drainage system of Arizona and New Mexico. It requires cool, clear water with stable temperatures and abundant aquatic vegetation, typically found in desert spring oases at elevations between 1,000-4,000 feet.

Why is Pyrgulopsis gilae classified as Vulnerable?
Pyrgulopsis gilae is classified as Vulnerable because the population is declining and the species faces a high risk of extinction in the medium-term future if current pressures continue. Pyrgulopsis gilae faces severe threats from groundwater depletion and habitat modification in its limited spring systems within the Gila River basin. Agricultural water extraction and urban development have reduced spring flow rates, while livestock grazing and recreational activities have degraded the delicate aquatic vegetation communities these snails depend upon. Climate change compounds these pressures by increasing evaporation rates and reducing groundwater recharge in the already arid southwestern United States.
Where does Pyrgulopsis gilae live?
Pyrgulopsis gilae occurs in United States. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Pyrgulopsis gilae?
The main threats to Pyrgulopsis gilae are ai-1, ai-2, ai-3, and ai-4. The full IUCN-classified threat record for this species is detailed on the species page.
