Assessment Information [top]

Red List Category & Criteria: Critically Endangered B2ab(iii) ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Needs updating
Assessor(s): Claudia Cortez, Steffen Reichle, Ignacio De la Riva, Jörn Köhler
Reviewer(s): Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson, Neil Cox and Bruce Young)
Listed as Critically Endangered because its Area of Occupancy is probably less than 10km2, all individuals are in a single sub-population, and the quality of its habitat in the Brazilian Andes is declining.

Geographic Range [top]

Range Description: This species is known only from the canyon of the Río Huayllamarca, in Carangas Province, Oruro Department, in the Bolivian Andes, at around 3,965m asl.
Countries occurrence:
Bolivia, Plurinational States of

Population [top]

Population: It is fairly common at the type locality.
Current Population Trend: Decreasing
Additional data:
Population severely fragmented: No

Habitat and Ecology [top]

Habitat and Ecology: It lives in streams in high-elevation puna grassland habitats, where it presumably breeds by larval development.
Systems: Terrestrial; Freshwater

Threats [top]

Major Threat(s): Populations are possibly affected by water pollution from agriculture, over-harvesting for medicinal use, and the deviation of water from streams for the irrigation of crops. Although not yet recorded, chytridiomycosis is a potential future threat.

Conservation Actions [top]

Conservation Actions: It is not recorded from any protected areas. Habitat protection and maintenance is recommended, complemented by more general actions to mitigate the effects of water pollution and channelization, and to manage exploitation. Close monitoring of surviving populations of this species is required.
