Taxonomy [top]

Kingdom Phylum Class Order Family

Scientific Name: Telmatobius colanensis
Species Authority: Wiens, 1993
Common Name(s):
English Colan Water Frog

Assessment Information [top]

Red List Category & Criteria: Endangered A3e ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Needs updating
Assessor(s): Javier Icochea, Edgar Lehr, 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.

Geographic Range [top]

Range Description: This species is known only from the Cordillera El Colán, in Amazonas Department in the northern Peruvian Andes, at 2,410m asl. It might occur a little more widely.

Population [top]

Population: Nothing is known about its population status.
Population Trend: Unknown

Habitat and Ecology [top]

Habitat and Ecology: This is a riparian, semi-aquatic species of rocky high-gradient streams in undisturbed cloud forest. It is not known if it can occur in disturbed habitat.
Systems: Terrestrial; Freshwater

Threats [top]

Major Threat(s): Outside existing protected areas, the major threat is likely to be ongoing forest loss. Populations of other species in the genus living at high elevations are very susceptible to infection with chytridiomycosis. The pathogen has yet to be reported from Telmatobius colanensis, but congeners nearby in Ecuador have disappeared, and so this species would appear to be seriously at risk.

Conservation Actions [top]

Conservation Actions: Survey work is needed to establish the population status of this species, and it requires careful population monitoring, particularly given the risk of chytridiomycosis. It is present within the Cordillera El Colán protected area.
