Stygobromus montanus

Unknown

Overview

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

Stygobromus montanus faces significant threats from groundwater contamination and aquifer depletion due to agricultural runoff and urban development in its limited range. The species' obligate dependence on pristine groundwater systems makes it extremely vulnerable to pollution from surface activities. Climate change poses additional risks through altered precipitation patterns that could affect groundwater recharge rates and water table levels critical for the species' survival.
