Gonyostomus goniostomus

Unknown

Overview

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

Gonyostomus goniostomus faces severe population decline primarily due to extensive deforestation and habitat fragmentation across its limited range in Atlantic Forest remnants. Agricultural expansion, particularly cattle ranching and sugarcane cultivation, has eliminated vast areas of suitable forest habitat. Urban development and infrastructure projects continue to fragment remaining forest patches, isolating small populations and reducing genetic diversity.

Threat summary

Habitat

This species inhabits primary and secondary Atlantic Forest (Mata Atlântica) in southeastern Brazil, preferring dense understory vegetation in humid lowland and montane forests. It requires continuous forest cover with thick leaf litter and fallen logs that provide shelter and foraging opportunities.
