Assessment Information [top]

Red List Category & Criteria: Endangered B1ab(iii) ver 3.1
Year Published: 2007
Date Assessed: 2007-03-01
Assessor(s): Campbell, J.A.
Reviewer(s): Cox, N., Chanson, J.S. & Stuart, S.N. (Global Reptile Assessment Coordinating Team)
Listed as Endangered because its extent of occurrence is less than 5,000 kmĀ², its distribution is severely fragmented, and there is continuing decline in the extent and quality of its forest habitat.

Geographic Range [top]

Range Description:This Mexican species is known only from two specimens collected in the vicinity of the type locality on Cerro Zempoaltepec, three animals from close to Totontepec (including a recent, 2007, specimen), and a single animal from the Sierra Juarez (described as Abronia kalaina) (J. Campbell and D. Church pers. comms.). It was collected between 2,158 and 2,438 m asl.

Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: This is an canopy species that needs mature trees in cloud forest habitat.
Systems: Terrestrial

Threats [top]

Major Threat(s): The species is threatened through conversion of land to agricultural use. Subsequent to the 1985 collections, there has been substantial deforestation within the species range.

Conservation Actions [top]

Conservation Actions: While this species is protected by Mexican law under the category Pr (Special Protection), it is not known to occur within any protected areas. There is a need to conserve suitable remaining areas of cloud forest within the species recorded range. Further studies into the geographic range, ecology and threats to this species are needed.
