Gammarus bousfieldi

Unknown

Overview

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

Gammarus bousfieldi faces significant threats from groundwater extraction and aquifer depletion, which directly impacts the water levels and quality of its specialized cave and spring habitats. Urban development and agricultural activities in the surrounding watershed pose additional risks through potential contamination and altered hydrology. The species' extremely limited distribution makes it particularly vulnerable to any localized environmental changes or disturbances.
