Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2009
Date Assessed: 2007-04-22
Assessor(s): Brown, R., Diesmos, M., Afuang, L., Rico, E. & Duya, M.R.
Reviewer(s): Cox, N. & Hoffmann, M. (Global Reptile Assessment Coordinating Team)
Listed as Least Concern in view of its wide distribution, presumed large population, it occurs in a number of protected areas, has a tolerance of a degree of habitat modification, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.

It very abundant in this habitat, but does not appear to be restricted to it, being found in secondary forest and disturbed areas, and in agricultural areas adjacent to forest.

Threats [top]

Major Threat(s): Severe habitat loss due to deforestation is a threat to this species. The species is traded at a low level (mainly within the local pet trade), and this seems unlikely to be a major threat.

Conservation Actions [top]

Conservation Actions: The species is found in a number of protected areas. Other than general research activities, no direct conservation measures are needed for this species as a whole.
