Description complète des menacesTexte détaillé évaluation IUCNExpert

This species experiences continuing decline in EOO, AOO, habitat quality, number of locations and number of mature individuals because of habitat destruction due to forest exploitation, mining and shifting cultivation. A subpopulation of this species has been recorded on the footprint of a mining project undergoing intense human pressure such as forests clearing. This former subpopulation must be considered as extirpated. One other subpopulation is known from an unprotected forest (Ambatolaona - La Mandraka) subjected to selective logging, timber harvesting for small-scale subsistence and tavy (slash-and-burn farming).
