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 km

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.


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

Population Trend


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).
