Assessment Information [top]

Red List Category & Criteria: Critically Endangered A2e ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Needs updating
Assessor(s): María Cristina Ardila-Robayo, Mariela Osorno-Muñoz
Reviewer(s): Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson, Neil Cox and Bruce Young)
Listed as Critically Endangered because of a projected population decline, estimated to be more than 80% over the next ten years, inferred from declines in other high altitude Atelopus species in the same region, probably due to chytridiomycosis.

Geographic Range [top]

Range Description:This species is found in Santuario de Fauna y Flora Guanentá Alto Río Fonce, Río Cañaverales, Santander Department, Colombia, at 1,700-2,000m asl.

Population [top]

Population:During the course of multiple visits undertaken in 1979-1982, this species was found to be common. There have been no subsequent surveys for the species, with the exception of one survey in 1992 when this species was not recorded, suggesting a serious decrease.
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:It is an inhabitant of cloud forest, with breeding and larval development taking place in streams. It tolerates disturbed forest.
Systems:Terrestrial; Freshwater

Threats [top]

Major Threat(s): The most serious risk to this species is chytridiomycosis, which has had a devastating impact on other high-altitude species of Atelopus.

Conservation Actions [top]

Conservation Actions: It occurs in the Santuario de Fauna y Flora Guanentá Alto Río Fonce. Further survey work is required to determine the biology and population status of this species. Given the threat of chytridiomycosis, successful conservation measures will probably need to include the maintenance of any surviving individuals in captivity.
