Acrorumohra hasseltii

Unknown

Overview

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

Acrorumohra hasseltii faces severe pressure from deforestation and habitat conversion across its Southeast Asian range, particularly in lowland and montane forests that are being cleared for palm oil plantations and agricultural development. The species' specialized epiphytic lifestyle makes it extremely vulnerable to forest fragmentation, as it requires mature forest canopy structure and specific microclimate conditions that are lost when forests are logged or converted.

Threat summary

Habitat

This epiphytic fern inhabits the canopy of tropical rainforests, growing on tree trunks and branches in both lowland and montane forests across Southeast Asia. It requires the humid, shaded microclimate conditions found in mature forest ecosystems, typically at elevations ranging from sea level to approximately 1,500 meters.
