Adiantum fengianum

Unknown

Overview

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

Adiantum fengianum faces severe pressure from limestone quarrying activities that directly destroy its specialized cave and karst habitat. The species' extremely limited distribution makes it particularly vulnerable to habitat modification, as entire populations can be eliminated by single quarrying operations. Urban development and infrastructure expansion in its native range further fragment the already restricted limestone formations where this fern occurs.

Threat summary

Habitat

This endemic fern inhabits limestone caves, crevices, and shaded karst formations in tropical regions. It requires the specific microclimate conditions found in these calcium-rich environments, including high humidity and filtered light.
