PROTECTION STATUS: Endangered
YEAR LISTED: 1997
CRITICAL HABITAT: 38 surface acres and 138 subsurface acres of subsurface habitat finalized in 2013
RECOVERY PLAN: None
RANGE: Comal Springs, Hueco Springs, and the Edwards Aquifer in Comal County, Texas
THREATS: Decreased spring flow due to increased use of groundwater resources; drought; increased flooding and erosion, pollution, siltation, and storm-water runoff associated with urbanization; and the presence of exotic species
POPULATION TREND: The Peck's cave amphipod is currently thought to be confined to small areas surrounding the spring openings of Comal Springs and Hueco Springs and the associated Edwards Aquifer. Numerous specimens have been collected from Comal Springs, and one specimen was collected from Hueco Springs in 1992. Limited data have been collected on the extent to which this species exists below ground.
