Pseudoniphargus grandimanus

Unknown

Overview

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

Pseudoniphargus grandimanus faces severe threats from groundwater extraction and pollution in its limited karst aquifer habitat. The species' extremely restricted range makes it highly vulnerable to any disturbance of the underground water systems it depends upon. Urban development and agricultural intensification in the surrounding landscape pose additional risks through contamination of the groundwater table.
