Overview

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

Karstama balicum faces severe threats from limestone quarrying and mining activities that directly destroy its specialized cave habitats in Bali's karst formations. The species' extremely restricted range makes it particularly vulnerable to habitat modification, while tourism development and infrastructure expansion in the region continue to fragment remaining suitable cave systems.
