Assessment Information [top]

Red List Category & Criteria: Vulnerable B1ab(iii) ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Assessor(s): Georgina Santos-Barrera, Luis Canseco-Márquez
Reviewer(s): Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson, Neil Cox and Bruce Young)
Justification:
Listed as Vulnerable because its Extent of Occurrence is less than 20,000 km2, its distribution is severely fragmented, and there is continuing decline in the extent and quality of its forest habitat in southern Mexico.

Geographic Range [top]

Range Description: This species is known from extreme southern Michoacán and México (state) in Mexico, south and east along the Pacific slope to western Guatemala. It also occurs in Veracruz and eastern Oaxaca, Mexico, on the Atlantic slope. In Guatemala it is known from above 2,000m asl.

Habitat and Ecology [top]

Habitat and Ecology: It occurs in a great variety of habitats, from lowland forests (tropical rainforest, tropical semi-deciduous forest) to montane pine and pine-oak forests, and cloud forests. It can survive in secondary forests, but not in open habitats. It breeds by direct development.
Systems: Terrestrial

Threats [top]

Major Threat(s): The major threat is the clearance of forest habitat for agriculture and as a result of logging, which is probably leading to the disappearance of shade, humidity and leaf-litter microhabitats on which the species depends.

Conservation Actions [top]

Conservation Actions: This species occurs in Reserva de la Biósfera El Triunfo in Mexico.
