Stenochlaena hainanensis

Unknown

Overview

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

Stenochlaena hainanensis faces severe pressure from rapid deforestation and agricultural expansion across its limited range in Hainan Island and southern China. The species' specialized habitat requirements make it particularly vulnerable to forest fragmentation, as it depends on specific microclimate conditions found in intact tropical forests. Urban development and infrastructure projects have further reduced available habitat, while climate change threatens to alter the moisture and temperature regimes essential for this fern's survival.

Threat summary

Habitat

This climbing fern inhabits humid tropical forests, typically growing as an epiphyte or climbing vine in the understory and canopy of primary and secondary forests. It requires consistent moisture levels and filtered sunlight found in intact forest ecosystems across Hainan Island and adjacent regions of southern China.
