Great apes in zoos require exceptional levels of cognitive stimulation, social complexity, and space to maintain good welfare, making them among the most challenging species to manage well.
Great ape welfare in zoos represents the highest bar in zoo animal management. These animals have complex long-term social memories, engage in sophisticated political behaviour, and require years of stable social relationships to develop normally. Inadequate social groups, insufficient space, and poor cognitive enrichment produce welfare outcomes that are visible and disturbing. The best great ape exhibits provide multi-hectare habitats, complex social groups, and daily cognitive challenge through food enrichment, tool-use opportunities, and choice about how to spend their time.
