Enrichment science provides evidence-based approaches to improving zoo animal welfare through environmental complexity.
Stereotypic behaviors in zoo animals — pacing, head-weaving, bar-chewing — indicate chronic frustration from understimulating environments. Effective enrichment provides outlet for natural behaviors including foraging, problem-solving, and social interaction. The science of enrichment has advanced substantially: evidence-based programs targeting specific behavioral needs are far more effective than adding novel objects alone.
