Description complète des menacesTexte détaillé évaluation IUCNExpert
Event though the species occurs in protected areas it is affected by human activities. The main threats are logging for timber and for charcoal production, causing habitat reduction and degradation, and therefore the decrease of mature individuals. The species grows in shaded areas and when the forest is cleared the specimen can not survive in the intense direct sunlight. Another threat for this species is the extraction of the calcareous rock the species grows in for sapphire mining in areas of the Ankara protected area.
