Assessment Information [top]

Red List Category & Criteria: Endangered A3e; B1ab(iii) ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Needs updating
Assessor(s): Javier Icochea, Erik Wild, César Aguilar Puntriano
Reviewer(s): Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson, Neil Cox and Bruce Young)
Listed as Endangered because of a population decline, projected to be more than 50% over the next 10 years, inferred from the potential impact of chytridiomycosis on populations of this species; and because its Extent of Occurrence is less than 5,000 km2, its distribution is severely fragmented, and there is continuing decline in the extent and quality of its habitat in the northern Peruvian Andes

Geographic Range [top]

Range Description:This species is known only from the Cordillera de Huancabamba (in Piura Department) at an altitude of 1,840-3,080m asl.

Population [top]

Population:It is an uncommon species.
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:It is a riparian, semi-aquatic, stream-breeding frog, and can be found under rocks in streams in very humid montane forest, humid lower montane forest and possibly dry lower montane forest. It may occur in disturbed areas, where water quality remains good, and has been recorded close to towns and agricultural areas.
Systems:Terrestrial; Freshwater

Threats [top]

Major Threat(s): There are no current major threats known for the areas occupied, though there may be some localized stream degradation. However, Telmatobius populations living at high elevations are particularly prone to infection with chytridiomycosis, and, although the pathogen has yet to be reported from T. ignavus, congeners nearby in Ecuador have disappeared, and so this species would appear to be seriously at risk.

Conservation Actions [top]

Conservation Actions: It is not known to be present in any protected areas. This species requires careful population monitoring, particularly given the risk of chytridiomycosis.
