Overview

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

Stygobromus onondagaensis faces primary threats from groundwater contamination and aquifer depletion in its limited range around Onondaga County, New York. Urban development and agricultural runoff pose significant risks to the pristine groundwater systems this amphipod requires. The species' extremely restricted distribution makes it particularly vulnerable to localized pollution events or hydrological changes that could affect its cave and groundwater habitats.
