Description complète des menacesTexte détaillé évaluation IUCNExpert
The major threat to this species is illicit collection for local, national and international trade, although there are no detailed statistics on the amount of harvesting presently occurring (L. Rajaovelona pers. obs.). The logging of forest, continuing practice of "tavy" (slash and burn) agriculture, burning, and charcoal production are also known to be disturbing the species' habitat by removing the host trees on which this epiphytic species grows and changing the forest humidity and light levels to which the species is adapted - likely causing a localized decrease in abundance. Pesticide use causes declines in the specific pollinators of some orchids on Madagascar (J. Andriantiana pers. obs.)

Mesures de conservation recommandéesStratégies de conservation IUCNExpert
There are no known conservation measures specifically for this species, but it is currently known to occur in several Protected Areas: Tsaratanana, Analamazaotra-Périnet, Mantadia, Ranomafana, Pic d'Ivohibe and Itremo New Protected Area. Seed collection through the Millennium Seed Bank Project in partnership with PBZT for ex situ storage and in vitro propagation contributes to the long-term conservation of this species.
