Western lowland gorillas are critically endangered great apes requiring sophisticated social management in captivity. Their welfare depends on appropriate group structures and complex, stimulating environments.
Zoo gorilla welfare centers on appropriate social structure, as gorillas are fundamentally social animals who suffer in isolation or inappropriate group configurations. Bachelor group management for males without breeding placement is a welfare challenge — these groups can be stable when well-managed but require significant space and careful composition. Silverback males in breeding groups must have sufficient social control and appropriate females to maintain psychological stability. Enrichment must engage their cognitive complexity including problem-solving feeders, novel food presentations, browse species variation, and positive interactions with familiar keepers. Exhibits should provide visual barriers allowing individuals to control social interaction. The welfare science for gorillas draws on decades of research and supports clear best practice standards.
