Overview

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

Western gorillas face severe population declines primarily due to commercial bushmeat hunting, which has intensified with improved road access to remote forest areas. The Ebola virus has caused catastrophic die-offs, with some populations experiencing mortality rates exceeding 90%. Logging operations fragment their habitat and facilitate human access, while agricultural expansion continues to reduce available forest cover.

Threat summary

Habitat

Western gorillas inhabit dense tropical rainforests across equatorial Africa, preferring primary and secondary forests with abundant fruit trees. They occupy both lowland and montane forest ecosystems up to 1,600 meters elevation, requiring large territories with diverse vegetation for foraging.

Frequently asked questions

Why is Gorilla gorilla classified as Critically Endangered?
Gorilla gorilla 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. Western gorillas face severe population declines primarily due to commercial bushmeat hunting, which has intensified with improved road access to remote forest areas. The Ebola virus has caused catastrophic die-offs, with some populations experiencing mortality rates exceeding 90%. Logging operations fragment their habitat and facilitate human access, while agricultural expansion continues to reduce available forest cover.
Where does Gorilla gorilla live?
Gorilla gorilla occurs in Angola, Cameroon, Central African Republic, Congo - Brazzaville, Equatorial Guinea, and Gabon (plus 1 other countries). Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Gorilla gorilla?
The main threats to Gorilla gorilla are 1.1, 11.1, 2.1, and 2.3. The full IUCN-classified threat record for this species is detailed on the species page.
