Description complète des menacesTexte détaillé évaluation IUCNExpert
This species is restricted to a very short length of a single stream in a residential area. Throughout the area, trees are being cleared for access and farming and it appears that this species cannot survive where the trees fringing the stream are cleared. It is highly likely that unless some form of control is imposed or an area demarcated within which the trees should not be cleared, the population will be lost through continued tree clearance. There is also a risk from urban development.
