Bulbophyllum octorhopalon

Unknown

Overview

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

Bulbophyllum octorhopalon faces severe threats from deforestation and habitat conversion in its limited range within Madagascar's eastern rainforests. The species' extremely restricted distribution makes it particularly vulnerable to localized disturbances, while collection pressure for the international orchid trade poses an additional risk to remaining wild populations. Climate change-induced shifts in rainfall patterns and temperature regimes threaten the specific microhabitat conditions this epiphytic orchid requires for survival.

Threat summary

Habitat

This epiphytic orchid inhabits the humid montane rainforests of eastern Madagascar, typically growing on moss-covered tree branches and trunks in areas with consistent moisture and filtered sunlight. The species requires specific microclimate conditions found in undisturbed primary forest at elevations between 800-1200 meters.
