Taxonomy [top]

Kingdom Phylum Class Order Family
ANIMALIA CHORDATA AMPHIBIA ANURA BUFONIDAE

Scientific Name: Atelopus simulatus
Species Authority: Ruíz-Carranza & Osorno-Muñoz, 1994

Assessment Information [top]

Red List Category & Criteria: Critically Endangered A2ace ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Assessor(s): Alonso Quevedo Gil, Jose Vicente Rueda, Wilmar Bolívar
Reviewer(s): Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson, Neil Cox and Bruce Young)
Justification:
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 of the population, probably due to chytridiomycosis.

Geographic Range [top]

Range Description: This species is known from the central Andes of Colombia, from Cauca and Tolima Departments, between 2,500 and 3,000m asl.

Population [top]

Population: Before 1999 this was a common species, but it has only been recorded once since then (2001) at a single locality despite numerous searches. A serious decline appears to have taken place.
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: It occurs on the ground near streams and also in open areas; it has not been recorded from anthropogenically disturbed habitats. The tadpoles develop 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 loss due to agricultural expansion (including the planting of illegal crops), as well as water pollution from agriculture, are major threats to the species. Climate change might also be a threat, but this needs to be investigated further.

Conservation Actions [top]

Conservation Actions: It is not known whether or not this species occurs in any protected areas. Further survey work is needed to determine whether or not this species still survives. Given the threat of chytridiomycosis, recommended conservation measures should include the establishment of a captive-breeding programme.
