Description complète des menacesTexte détaillé évaluation IUCNExpert
Most forest in the areas in which this species occurs has been cleared for small-scale agriculture, although some forest remains on higher ground. Remaining habitat is threatened by the ongoing degradation of habitats through intensive logging, transformation to large-scale agriculture, indiscriminate discharge of industrial waste and domestic sewage as well as illegal gold extraction in most rivers. It is also threatened by collection from the wild for the plant trade.
