Callicebus barbarabrownae

Declining

Overview

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

Callicebus barbarabrownae faces severe habitat destruction from deforestation and agricultural expansion in its extremely limited range in Bahia, Brazil. The species' tiny population is further threatened by habitat fragmentation that isolates breeding groups and reduces genetic diversity. Mining activities and urban development continue to encroach on remaining forest patches, while the species' specialized dietary requirements make it particularly vulnerable to ecosystem disruption.

Threat summary

Frequently asked questions

Why is Callicebus barbarabrownae classified as Critically Endangered?
Callicebus barbarabrownae is classified as Critically Endangered — facing an extremely high risk of extinction in the wild — because population sizes are very small, declining sharply, or restricted to a tiny range. Callicebus barbarabrownae faces severe habitat destruction from deforestation and agricultural expansion in its extremely limited range in Bahia, Brazil. The species' tiny population is further threatened by habitat fragmentation that isolates breeding groups and reduces genetic diversity. Mining activities and urban development continue to encroach on remaining forest patches, while the species' specialized dietary requirements make it particularly vulnerable to ecosystem disruption.
Where does Callicebus barbarabrownae live?
Callicebus barbarabrownae occurs in Brazil. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Callicebus barbarabrownae?
The main threats to Callicebus barbarabrownae are 1.1, 2.1, 2.3, and 4.1. The full IUCN-classified threat record for this species is detailed on the species page.
