Bulbophyllum gnomoniferum

Declining

Overview

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

Bulbophyllum gnomoniferum 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 horticultural trade poses additional risks 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, growing on tree trunks and branches in the forest canopy at elevations between 800-1,200 meters. It requires consistently high humidity levels and filtered sunlight typical of intact primary forest ecosystems.

Frequently asked questions

Why is Bulbophyllum gnomoniferum classified as Critically Endangered?
Bulbophyllum gnomoniferum is classified as Critically Endangered — facing an extremely high risk of extinction in the wild — because population sizes are very small, declining sharply, or restricted to a tiny range. Bulbophyllum gnomoniferum 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 horticultural trade poses additional risks 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.
Where does Bulbophyllum gnomoniferum live?
Bulbophyllum gnomoniferum occurs in Philippines. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Bulbophyllum gnomoniferum?
The main threats to Bulbophyllum gnomoniferum are 10.1, 2.1, 2.1.1, and 3.3. The full IUCN-classified threat record for this species is detailed on the species page.
