Assessment Information [top]

Red List Category & Criteria:	Endangered B1ab(iii) ver 3.1
Year Published:	2007
Assessor/s:	Campbell, J.A. & Muñoz-Alonso, A.
Reviewer/s:	Cox, N., Chanson, J.S. & Stuart, S.N. (Global Reptile Assessment Coordinating Team)
Contributor/s:
Justification: Listed as Endangered because its extent of occurrence is less than 5,000 km², all individuals are in fewer than five locations, and there is continuing decline in the extent and quality of its habitat.

Geographic Range [top]

Range Description:	This species is present in southwestern Guatemala and southeastern Chiapas, Mexico. In Guatemala, it is known only from two localities on the Pacific versant near San Marcos. In Mexico, this species is known only from Volcan Tacana. It is found at elevations between 1,950 to 2,630 m asl.
Countries:	Native: Guatemala; Mexico

Population [top]

Population:	Owing to the species arboreal habits, it is difficult to determine how common it is. The species was recorded in Mexico during 2004.
Population Trend:	Decreasing

Habitat and Ecology [top]

Habitat and Ecology:	It is an arboreal species present within cloud forest and is also found close to the pine-cypress zone. It is an arboreal species, and populations need forest with mature, tall trees to persist. It is unlikely that this species can occur in heavily deforested habitat. The species is known to persist, where tall trees remain, in areas used for shade-grown coffee by indigenous peoples.
Systems:	Terrestrial

Threats [top]

Major Threat(s):	There has been large-scale deforestation within the species range, generally through the conversion of land to agricultural use. Populations can however persist where large trees remain.
