Gorillas are highly social great apes whose psychological complexity creates significant welfare challenges and responsibilities in zoo management.
Gorilla welfare in zoo settings requires genuine understanding of their social and psychological complexity. These animals live in long-term stable social structures where relationships are maintained over decades. Management decisions that disrupt established groups for breeding or facility reasons have significant psychological welfare costs. The most progressive zoo gorilla programmes invest heavily in social management, enrichment design, and ongoing monitoring of individual welfare indicators. Behavioural indicators including play frequency, social interaction quality, and absence of stereotypies provide insight into psychological state that physical health indicators alone cannot capture.
