Adiantum sinicum
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Adiantum sinicum faces severe population decline primarily due to habitat destruction from urban development and agricultural expansion across its limited range in China. The species is particularly vulnerable to limestone quarrying activities that destroy the specific calcareous rock crevices it requires for survival. Collection pressure for horticultural trade has further reduced wild populations, as this attractive fern is sought after for traditional gardens and modern landscaping projects.
Habitat
This endemic Chinese fern grows exclusively in crevices of limestone cliffs and calcareous rock faces, typically in shaded or semi-shaded locations at elevations between 200-800 meters. It requires specific moisture conditions and alkaline substrates found only in karst limestone formations.
