Procambarus franzi

Unknown

Overview

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

Procambarus franzi faces severe threats from groundwater depletion and contamination in its limited karst cave systems. Urban development and agricultural runoff in the surrounding landscape directly impact the water quality of its underground habitat. The species' extremely restricted range makes it particularly vulnerable to any disturbance to its cave ecosystem, with pollution events potentially affecting the entire known population.
