Procambarus hortonhobbsi

Unknown

Overview

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

Procambarus hortonhobbsi faces severe threats from groundwater depletion and contamination in its limited karst habitat range. Urban development and agricultural intensification have altered surface water flow patterns that feed the cave systems this species depends upon. Water quality degradation from agricultural runoff and residential development poses additional risks to the delicate aquatic cave ecosystems where this crayfish survives.

Threat summary

Habitat

This species inhabits freshwater cave systems and associated karst aquifers in limestone regions of the southeastern United States. It requires stable groundwater levels and clean, well-oxygenated cave waters with minimal surface contamination.
