|Scientific Name:||Alsodes tumultuosus|
|Species Authority:||Veloso, Iturra-Constant & Galleguillos, 1979|
|Red List Category & Criteria:||Critically Endangered B1ab(iii,v)+2ab(iii,v) ver 3.1|
|Assessor(s):||Alberto Veloso, Herman Núñez|
|Reviewer(s):||Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson, Neil Cox and Bruce Young)|
Listed as Critically Endangered because its Extent of Occurrence is less than 100 km2 and its Area Of Occupancy is less than 10km2, all individuals are in a single location, and there is continuing decline in the number of mature individuals, and in the extent and quality of its habitat around Farellones.
|Range Description:||This species is known only from Farellones (33° 32'S; 70°19'W), Central Chile, 35km north-east of Santiago, at an altitudinal range of 2,300-3,000m asl, though it is possibly more widely distributed.|

|Population:||The population is currently believed to comprise only a few adults. Like its congener, A. montanus, it was last collected in 2003, and the population has declined substantially in recent years. Areas where the species is known to breed were found to have been completely destroyed by February 2002.|
|Habitat and Ecology:||This stream-breeding species has been found under stones, close to mountain streams, where the surrounding vegetation comprises grasses and shrubs characteristic of cold Andean areas. It has free-swimming tadpoles.|
|Major Threat(s):||Currently, the primary threat to this species is from recreational skiing and tourist infrastructure development, since the only known locality where the species is found is in a ski resort.|
|Conservation Actions:||Protection and maintenance of its existing habitat is a priority for this species, as it is currently not known from any protected area.|
