Octarrhena saccolabioides

Declining

Overview

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

Octarrhena saccolabioides faces severe threats from deforestation and habitat conversion in its limited montane forest range. The species' extremely restricted distribution makes it particularly vulnerable to localized disturbances, while climate change poses additional risks to its specialized high-altitude ecosystem. Agricultural expansion and logging activities continue to fragment the remaining suitable habitat.

Threat summary

Habitat

This orchid species inhabits montane forests at high elevations, typically growing as an epiphyte on moss-covered tree branches and trunks. It requires the cool, humid conditions and stable microclimate found in undisturbed cloud forest environments.
