Stygobromus wengerorum

Unknown

Overview

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

Stygobromus wengerorum faces severe threats from groundwater contamination and aquifer depletion in its limited range within the Edwards Aquifer system of Texas. Urban development and agricultural activities above the cave systems introduce pollutants that directly impact the pristine groundwater environments this species requires. Water table fluctuations from excessive pumping can alter the delicate hydrological conditions of occupied caves, while surface contamination from pesticides and urban runoff poses ongoing risks to water quality.

Threat summary
