Ribeirao Button Frog

Cycloramphus acangatan

Unknown

Overview

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

Cycloramphus acangatan faces severe pressure from habitat destruction as Atlantic Forest fragments continue to be cleared for agriculture and urban development. The species' dependence on pristine stream environments makes it particularly vulnerable to water pollution from agricultural runoff and sedimentation. Climate change poses an additional threat by altering precipitation patterns and stream flow regimes essential for its reproductive cycle.

Threat summary
