Assessment Information [top]

Red List Category & Criteria: Critically Endangered A2ace ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Needs updating
Assessor(s): Georgina Santos-Barrera, Luis Canseco-Márquez
Reviewer(s): Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson, Neil Cox and Bruce Young)
Listed as Critically Endangered because of a drastic population decline, estimated to be more than 80% over the last three generations, inferred from the apparent disappearance of most, or all, of the population, probably due to chytridiomycosis.

Geographic Range [top]

Range Description:This species occurs in the Sierra Madre del Sur in southern Oaxaca, north to about San Gabriel Mixtepec and Jalatengo, Mexico, at between 1,200 and 1,700m asl.

Current Population Trend:Decreasing
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This species inhabits cloud forest. It generally dwells on low vegetation along streams, and breeds in permanent streams.
Systems:Terrestrial; Freshwater

Threats [top]

Major Threat(s): The destruction and degradation of its cloud forest habitat is a major threat to this species, and there is high pressure from infrastructure development for human settlements, and other anthropogenic activities in this region. However, this species has also disappeared in suitable habitat, probably due to chytridiomycosis.

Conservation Actions [top]

Conservation Actions: This species is not known to occur in any protected areas. There is a need for further survey work in areas of suitable habitat in order to determine whether or not this species still survives in its natural range, and to evaluate the present condition of the forested areas north to San Gabriel Mixtepec. The protection of remaining intact habitat within this area is recommended.
