Overview

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

The Rivera Redbelly Toad faces severe habitat degradation from agricultural expansion and cattle ranching across its limited range in northern Uruguay and southern Brazil. Urban development and infrastructure projects have fragmented remaining suitable habitats, while pollution from agricultural runoff degrades water quality in breeding sites. Climate change poses additional risks through altered precipitation patterns that could disrupt the species' reproductive cycle.

Threat summary

Habitat
