Zoo Exhibit Design and Animal Welfare Science

The design of zoo exhibits profoundly affects animal welfare, with modern evidence-based design prioritising animal choice, space, complexity, and species-appropriate environmental features.

Key Facts

The Five Domains framework guides welfare-centred zoo exhibit design
Animals must have the ability to choose between different microhabitats within exhibits
Social housing arrangements must reflect natural group structures and allow conflict avoidance
Substrate quality affects foot health in many species including elephants and large felids
Visitor proximity and noise levels affect stress hormones in many zoo species

Welfare Considerations

Zoo exhibit design has shifted dramatically from the barred concrete enclosures of the past toward naturalistic, complex environments that support species-appropriate behaviours. Evidence from welfare science now informs every aspect of design: shade and sun for thermoregulation, elevated areas for surveillance, water features for swimming species, substrate depth for digging species. Critically, good exhibit design must also provide animals with agency - the ability to choose their location and proximity to visitors. Animals that can hide from visitors show lower stress responses and engage in more natural behaviours.

What You Can Do

Support accredited zoos that publicly report on exhibit design standards
Advocate for zoo accreditation requirements to include exhibit complexity standards
Ask zoos about off-exhibit spaces where animals can retreat from visitors
Support zoo welfare research programmes measuring animal responses to design changes
Choose zoos demonstrating commitment to exhibit improvement over static facilities
