Zoo Enrichment Science: Evidence-Based Positive Welfare

Modern zoo enrichment programmes increasingly focus on evidence-based approaches that deliver genuine positive welfare states.

Key Facts

Enrichment reduces stereotypic behaviour in captive animals by over 50% in many studies
Novelty, food-based, and social enrichment have different species-specific effects
Some enrichment designed by humans is not used by target animals - evaluation is essential
Positive welfare indicators (play, positive anticipation) distinguish thriving from merely coping

Welfare Considerations

Enrichment that is designed without evaluation can waste resources and miss welfare goals. Evidence-based enrichment that is chosen by animals, evaluated regularly, and rotated for novelty produces genuine improvements in positive welfare states.
