Cynorkis humbertii

Declining

Overview

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

Cynorkis humbertii faces severe threats from ongoing deforestation and habitat conversion in Madagascar's remaining rainforest fragments. The species' extremely limited range makes it particularly vulnerable to slash-and-burn agriculture (tavy) and logging activities that continue to fragment its montane forest habitat. Climate change poses an additional threat through altered precipitation patterns and temperature shifts that could affect the delicate ecological relationships this orchid depends upon for pollination and mycorrhizal associations.

Threat summary

Habitat

Cynorkis humbertii is endemic to the montane rainforests of eastern Madagascar, typically found growing as a terrestrial orchid in humid, shaded understory conditions at elevations between 800-1,500 meters. The species requires the specific microclimate conditions and mycorrhizal relationships found in intact primary forest ecosystems.
