Hancea wenzeliana

Declining

Overview

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

Hancea wenzeliana faces severe threats from habitat destruction due to limestone quarrying and urban development in its restricted karst cave systems. The species' extremely limited distribution makes it particularly vulnerable to localized disturbances, while pollution from agricultural runoff and industrial activities degrades the delicate cave ecosystems it depends upon. Climate change poses additional risks through altered groundwater levels and temperature fluctuations that could disrupt the stable cave environment essential for its survival.

Threat summary

Habitat

Hancea wenzeliana is endemic to limestone karst cave systems, where it inhabits the specialized microenvironments of cave walls, crevices, and humid chambers. This species requires the stable temperature, high humidity, and specific mineral conditions found in these subterranean limestone formations.
