Description complète des menacesTexte détaillé évaluation IUCNExpert
There are no threats which especially target this species. There are, however, threats to its general habitat. According to WWF (2017), Sumatra lost 55% of its natural forests between 1985 and 2014 and is projected to lose 5 million hectares between 2010 and 2030. Within the extent of occurrence, there has been over 17% tree cover loss in a 16 year period (GFW 2018). Satellite imagery (GFW 2018) shows degradation of the habitat quality in most of the locations where this species has been found.
