Asplenium alatum

Unknown

Overview

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

Asplenium alatum faces severe population decline due to habitat destruction from urban development and agricultural expansion across its limited range. The species' specialized requirements for specific rock crevices and moisture conditions make it particularly vulnerable to environmental changes. Overcollection by fern enthusiasts and botanical collectors has further reduced wild populations, while climate change threatens the delicate microhabitat conditions this epiphytic fern requires for survival.

Threat summary

Habitat

This epiphytic fern inhabits humid rock crevices, cliff faces, and limestone outcrops in tropical and subtropical regions. It requires consistently moist conditions and typically grows in shaded areas with high humidity levels.
