Western lowland gorillas are highly social primates whose welfare in captivity depends on complex, stable social groups and cognitively demanding enrichment that challenges their exceptional intelligence.
Gorilla welfare in captivity is fundamentally dependent on two factors: social group quality and cognitive stimulation. Solitary housing is a welfare emergency; bachelor groups, family groups, and mixed breeding groups all produce substantially better welfare outcomes than single housing. Cognitive enrichment must be varied, progressively challenging, and species-appropriate — gorillas quickly habituate to static enrichment and require novel challenges. Positive reinforcement training for voluntary participation in veterinary care reduces stress and enables better welfare monitoring.
