Procambarus regiomontanus

Declining

Overview

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

Procambarus regiomontanus faces severe threats from urban development and agricultural expansion in its limited range around Monterrey, Mexico. The species' restricted distribution to a few cave systems and springs makes it extremely vulnerable to groundwater depletion and pollution from industrial activities. Water extraction for municipal use and contamination from urban runoff have degraded the aquatic habitats essential for this crayfish's survival.
