Systems: Terrestrial; Freshwater

Threats [top]

Major Threat(s): Not threatened over the majority of its range. Habitat destruction and degradation (native forest loss) is a localized threat.

Conservation Actions [top]

Conservation Actions: A number of protected areas (more than 10) are present along the entire latitudinal range of Nannophryne variegata. Species is listed as "Insufficiently Known" (Inadecuadamente Conocida) by Chile (Reglamento de la Ley de Caza, Chile, 1998) for VIII, IX and X Regions. National legislation to preserve the native Nothofagus forest is necessary for Chile.
