Assessment Information [top]

Red List Category & Criteria: Critically Endangered A3ce ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Needs updating
Assessor(s): Jose Vicente Rueda, María Cristina Ardila-Robayo, Mariela Osorno-Muñoz, Ruth Adriana Maldonado-Silva, Enrique La Marca
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.

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.
Systems: Terrestrial; Freshwater

Threats [top]

Major Threat(s): The major threat is likely to be chytridiomycosis, leading to a catastrophic population decline, as has occurred in many other montane species of Atelopus. Habitat destruction due to potato farming is also a threat to this species.

Conservation Actions [top]

Conservation Actions: The species has not been recorded from any protected area, although it might occur in the Reserva Forestal Protectora El Predio Río Sucio, in the Municipio de Gachalá. Survey work is necessary to determine the current population status of the species. In view of the threat of chytridiomycosis, surviving individuals might need to be taken into captivity.
