Assessment Information [top]

Red List Category & Criteria: Vulnerable A3ce ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Needs updating
Assessor(s): Jean Lescure, Christian Marty, Renaud Boistel, Stefan Lötters, Enrique La Marca, Robert Reynolds, Marinus Hoogmoed, Ross MacCulloch, Philippe Gaucher, Stefan Lötters
Reviewer(s): Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson, Neil Cox and Bruce Young)
Listed as Vulnerable because of a projected population decline, estimated to be more than 30% over the next ten years, inferred from declines in other Atelopus species in the same region, probably due to chytridiomycosis.

Threats [top]

Major Threat(s): There are no present threats to this species, but future threats will most likely include shifting agriculture and clear-cutting of the forests. Although illegal, there is still some collection for the pet trade, but at present this is not a major threat to the species. This species probably occurs at elevations below the altitude at which chytridiomycosis seems prevalent, though this nonetheless remains a potential future threat.

Conservation Actions [top]

Conservation Actions: The range of this species includes Matoury Nature Reserve and Kaw Nature Reserve. Continued population monitoring is required, especially in light of the potential threat of chytridiomycosis.
