Assessment Information [top]

Red List Category & Criteria: Critically Endangered B2ab(iii) ver 3.1
Year Published: 2010
Date Assessed: 2008-11-21
Assessor(s): Alberto Veloso, Herman Núñez, Ramón Formas
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 500 km2, with all individuals in fewer than five locations, and there is a continuing decline in the extent and quality of its habitat in Arauco Province, Chile.

Population [top]

Population:It is extremely rare; extensive fieldwork by several herpetologists within the range of this species from 1992-2002 turned up only a single adult (in 2002).
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:It occurs in fast-flowing streams in temperate Nothofagus forest. The tadpoles are free-swimming and feed by scraping algae off of submerged rocks. It is tolerant of moderate habitat destruction.

Threats [top]

Major Threat(s): The major threat to the species is clear cutting and afforestation with pine plantations, which causes siltation of streams (which, in turn, makes it harder for the larvae to feed).

Conservation Actions [top]

Conservation Actions: It occurs in the Parque Nacional Nahuelbuta, but there is a need for additional protection and maintenance of habitat at sites at which this species is known to occur. Further survey work is required to determine the current population status of the species.
