Kingdom Phylum Class Order Family
ANIMALIA CHORDATA AMPHIBIA ANURA BUFONIDAE

Scientific Name: Atelopus lynchi
Species Authority: Cannatella, 1981
Taxonomic Notes: Rivero and Serna (1993 "1991") doubted that specimens from Valle del Cauca, Colombia, were correctly assigned to this species.

Assessment Information [top]

Red List Category & Criteria: Critically Endangered A3ce; B1ab(iii,iv,v) ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Assessor(s): Santiago Ron, Luis A. Coloma, Martín R. Bustamante, Wilmar Bolívar, Stefan Lötters, Juan Manuel Renjifo, Jose Vicente Rueda
Reviewer(s): Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson, Neil Cox and Bruce Young)
Justification:
Listed as Critically Endangered because of a predicted drastic population decline of more than 80% over the next ten years, due to chytridiomycosis, and because its Extent of Occurrence is less than 100 km2, its distribution is severely fragmented, and there is continuing decline in the extent and quality of its habitat, number of locations, and number of mature individuals.

Geographic Range [top]

Range Description: This species is endemic to the Pacific slopes of northern Ecuador (Maldonado in the Province of Carchi), between 800 and 1,410m asl. Records of this species from the western slope of the Cordillera Occidental, Valle del Cauca Department, in Colombia refer to an unidentified, probably un-named species.

Possibly extinct:

Population [top]

Population: This species has disappeared from Ecuador, and there have been no records from this country since 1984.
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: It lives on the border between lowland tropical rainforests and montane forests. It is terrestrial, presumably breeding in streams.
Systems: Terrestrial; Freshwater

Threats [top]

Major Threat(s): The major threat is likely to be chytridiomycosis, which has caused major declines in many other species of Atelopus. Additional threats include deforestation for agricultural development (including the planting of illegal crops), logging, and human settlement, and pollution resulting from the fumigation of illegal crops.

Conservation Actions [top]

Conservation Actions: This species is not known from any protected areas. Survey work is urgently required to determine whether or not this species still persists, and, in view of the severe risk of chytridiomycosis, any surviving populations should immediately form part of an ex-situ management programme.
