Description complète des menacesTexte détaillé évaluation IUCNExpert
Several threats affect this species due to its close location to a highly urbanised settlement. Only part of the habitat is protected. Establishment of human settlements, orchards, domestic agri-crop gardens and industrial agricultural plantations cause habitat destruction in areas that are not protected. Collection of firewood and non-timber forest products also threatens the habitat as does collection of plants for local ornamental purposes. There is a low to high vulnerability (depending on exact site) to soil erosion and landslides (Agoo and Madulid 2012).
