Geothelphusa yangminshan

Unknown

Overview

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

Geothelphusa yangminshan faces severe pressure from urban development and tourism infrastructure expansion around Yangmingshan National Park in northern Taiwan. The species' restricted range makes it particularly vulnerable to habitat fragmentation from road construction and recreational facility development. Water pollution from increased human activity and potential geothermal development in the region poses additional risks to the freshwater stream systems this endemic crab depends upon.

Threat summary
