Bythinella turca

Unknown

Overview

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

Bythinella turca faces severe threats from groundwater extraction and pollution in its limited spring habitat range in Turkey. The species' extremely restricted distribution makes it highly vulnerable to hydrological changes, with agricultural runoff and urban development degrading water quality in critical spring systems. Climate change poses additional risks through altered precipitation patterns that could affect groundwater levels essential for this endemic freshwater gastropod's survival.

Threat summary

Habitat

Bythinella turca inhabits freshwater springs and associated seepage areas in limestone karst terrain of Turkey. This endemic gastropod requires clean, cool spring waters with stable flow rates and specific mineral compositions typical of Mediterranean karst aquifer systems.
