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 is known only from Agua del Obispo at 980m asl, central Guerrero, Mexico, although it is likely to occur a little more widely.

Population [top]

Population:This has always been a rare species, but it appears to have gone into serious decline, and has not been recorded since 1984. Recent surveys to locate it have been unsuccessful, and it might now be extinct.
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:It has been recorded inhabiting pine-oak forests, and breeds by direct development.

Threats [top]

Major Threat(s): Loss of original forest cover due to conversion to agricultural land, and as a result of excessive logging, has had an impact of this species. However, it has also disappeared in suitable habitat, probably due to chytridiomycosis.

Conservation Actions [top]

Conservation Actions: This species is a priority for further survey work to determine whether or not it might still survive in the wild, and surviving populations might need to form the basis for a captive-breeding programme. The range of this species does not include any protected areas, and protection of the Agua del Obispo forests is urgent since there are many threatened amphibians known to occur in this area. It is protected by Mexican law under the "Special Protection" category (Pr).
