From the IUCN Red List Species Account:

 

Range Description

This species is known from 10 threat-defined locations from the Metropolitan region to the VI region of Chile, at altitudes between 2,000 and 3,000 m asl. It has an extent of occurrence of 6,343 km2.

Habitat and Ecology

This stream-breeding species has been found under stones, in mountain streams, where the surrounding vegetation comprises grasses characteristic of cold Andean areas. It has free-swimming tadpoles.

Population

The species seems to be more abundant than its congener A. montanus.

Population Trend

unknown

Major Threats

The primary threat in the northernmost location is from recreational skiing and tourist infrastructure development, as well as the associated pollution by sewage. Projected hydroelectric dams - some of which are already being constructed - will affect the species in the southern range in the near future. Chytridiomycosis has been found in high proportions in one sub-population (Farallones).

Conservation Actions

Conservation Actions
The species occurs in Reserva Nacional Río Cipreses.

Red List Status

Vulnerable (VU)

Rationale

Listed as Vulnerable because its extent of occurrence is 6,343 km2, there are no more than 10 locations, and several of them - especially in the extremes of its range - are threatened by human activities. In the north its habitat is being reduced by constructions related to the tourism industry (skiing), and the habitat quality is affected by pollution due to sewage. In the south, the construction of several hydroelectric dams has already been approved, and there is no doubt that this will affect the species directly and indirectly. Finally, chytridiomycosis has been identified in one of the sub-populations.
