Calycorectes australis

Unknown

Overview

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

Calycorectes australis faces severe pressure from agricultural expansion and urban development throughout its limited range in southeastern Brazil. The species' restricted distribution in Atlantic Forest fragments makes it particularly vulnerable to habitat fragmentation, while cattle ranching and sugarcane cultivation continue to reduce available forest cover. Climate change poses an additional threat by altering precipitation patterns critical for this moisture-dependent species.

Threat summary

Habitat

This endemic Brazilian species inhabits remnant Atlantic Forest fragments in southeastern Brazil, particularly in moist montane forests and forest edges. It typically occurs in areas with high humidity and consistent moisture levels, often in secondary growth forests recovering from past disturbance.
