Stygobromus reddelli

Unknown

Overview

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

Stygobromus reddelli faces severe threats from groundwater depletion and contamination in the Edwards Aquifer system of central Texas. Urban development and agricultural activities above its cave habitat introduce pollutants and alter natural water flow patterns. The species' extremely limited distribution in a few cave systems makes it particularly vulnerable to localized disturbances and water table fluctuations.
