Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

The southern torrent frog faces severe habitat degradation from logging activities and forest clearance on Yakushima Island, which fragments its specialized stream environments. Climate change poses an additional threat by altering precipitation patterns and stream flow regimes essential for this torrent-dwelling species. The species' extremely limited range on a single island makes it particularly vulnerable to environmental changes and human disturbance.

Threat summary

Habitat

This species inhabits fast-flowing mountain streams and torrents in the subtropical forests of Yakushima Island, Japan. It requires pristine riparian environments with rocky substrates and clean, well-oxygenated water typical of undisturbed montane forest ecosystems.
