Arachniodes tsiangiana

Unknown

Overview

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

Arachniodes tsiangiana faces severe pressure from rapid deforestation and agricultural expansion across its limited range in southern China. The species' specialized requirements for humid, shaded forest understory make it particularly vulnerable to habitat fragmentation, as remaining forest patches become too small and isolated to support viable populations. Urban development and infrastructure projects have further reduced available habitat, while climate change threatens to alter the cool, moist microclimate conditions essential for this fern's survival.

Threat summary

Habitat

This endangered fern species inhabits the humid understory of subtropical montane forests, typically growing on shaded forest floors and rocky slopes at elevations between 300-1,500 meters. It requires consistently moist conditions and filtered sunlight provided by dense canopy cover in its native range across southern China.
