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 in the conservation zone of a mining project undergoing intense human pressure such as forests clearing. One other subpopulation is known from an unprotected forest subjected to selective logging, timber harvesting for small-scale subsistence and tavy (slash-and-burn farming).
