Habitat and Ecology [top]

Use and Trade: This species is not used or traded.
Threats [top]
Major Threat(s): Deforestation is occurring in this region due to factors including logging, expansion of agriculture and the conversion of forest to plantation estates. The forest cover of Sumatra declined by 61% between 1985 and 1997 (Achmaliadi et al. 2002). The habitat of this species is "fragmented" (CBSG 2003). Most of the forest in Sumatra is already converted to oil palm plantations. In Malaysia, the known localities are in the highlands and have considerable remaining forest cover.
In Peninsular Malaysia the upland areas are generally protected, and the species is not currently thought to be seriously threatened in this part of its range.
Conservation Actions [top]
Conservation Actions: The only possible conservation area for this species in Sumatra is Bukit Tigapuluh National Park, but there are no herpetological records from this site. All other areas in eastern Sumatra are already converted to oil palm plantations. In Malaysia, the species occurs in Penang and Larut Hill, both of which are protected areas.
