Zoo Welfare Five Domains Framework

The Five Domains framework provides a comprehensive welfare assessment model for zoo animals that captures both physical and psychological welfare dimensions.

Key Facts

The Five Domains model includes nutrition, environment, health, behaviour, and mental state
It was developed by Professor David Mellor and represents the current gold standard in zoo welfare assessment
Mental state assessment goes beyond observable behaviour to consider affective experiences
The framework guides management decisions including habitat design and enrichment provision
Most major zoo accreditation bodies now reference the Five Domains in welfare requirements

Welfare Considerations

The Five Domains framework represents a conceptual advance over the Five Freedoms model by explicitly acknowledging that welfare includes positive as well as negative mental states. An animal that is not suffering is not necessarily thriving. The framework prompts zoo managers to ask not only whether needs are being met but whether positive experiences are being generated. This shift has driven practical management changes including enrichment programmes, choice provision, and habitat complexity improvements.
