Behavioural enrichment transforms zoo enclosures from static environments into spaces that allow animals to express natural behaviours, reducing stereotypies and improving psychological welfare.
The shift from bare concrete enclosures to enriched naturalistic habitats represents genuine welfare progress in modern zoos. However, enrichment programmes vary widely in quality and consistency. Some species, particularly large-brained animals like great apes, elephants, and cetaceans, have needs that even the best zoo enrichment cannot fully meet. Welfare assessment using validated tools and transparent public reporting are hallmarks of genuinely welfare-focused institutions.
