Range and habitat

This frog lives in Nothofagus forests, where it has been found under rocks in streams, near streams, and under logs with thick layers of leaf litter.

Pins are Wikidata “endemic to” fields. Orange dots, when present, are GBIF occurrence tiles — survey bias included.

Breeding

Calling males and egg sites define most frog field work. A species known from one ridge is as narrow as it sounds.

Eggs and damp skin make amphibians quick to vanish from a drained wetland or a forest stripped of litter.

In crisis

The IUCN classifies this frog as critically endangered, with threats among them gold mining, forest fires, and forest conversion to agriculture, tree plantations, and livestock cultivation.

Chytrid fungus, collection, and wet-forest loss are the usual pressures on frogs with a high threat category.

Alsodes cantillanensis is Critically Endangered on this catalog because that is the IUCN category stored on Wikidata. Confirm the official criteria and any later count on iucnredlist.org.
