Paraboea chiangdaoensis

Declining

Overview

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

Paraboea chiangdaoensis faces severe threats from limestone quarrying and cave tourism development in its restricted range around Chiang Dao Cave in northern Thailand. The species' extremely limited distribution makes it particularly vulnerable to habitat modification, as any disturbance to the cave entrance areas and surrounding limestone formations directly impacts the entire known population. Agricultural expansion and infrastructure development in the region further fragment the already minimal suitable habitat.
