Assessment Information [top]

Red List Category & Criteria: Vulnerable A3ce ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Needs updating
Assessor(s): Lescure, J., Marty, C., Boistel, R., Lötters, S., La Marca, E., Reynolds, R., Hoogmoed, M., MacCulloch, R. & Gaucher, P.
Reviewer(s): Stuart, S.N., Chanson, J.S., Cox, N.A. & Young, B.E.
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.

Current Population Trend:Stable
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This species is known from the proximity of fast-flowing small streams in lowland primary forest. It has not been recorded outside primary forest. Embryonic and larval development occurs in water.
Systems:Terrestrial; Freshwater

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.
