Gorillas are highly social primates with complex psychological needs. Zoo welfare science has identified key requirements for good welfare that guide accredited facilities.
Gorilla welfare in zoos depends critically on social group stability and composition. Introductions of new individuals are complex and stressful for all parties. Dominant males require opportunities to display, patrol, and socially control their groups. Space that allows group spread, privacy between individuals, and natural substrate exploration significantly improves welfare outcomes. EAZA accreditation requires adherence to evidence-based gorilla management guidelines.
