Modern zoos increasingly integrate conservation programs with on-site animal care. The welfare of zoo animals and the conservation of wild populations are complementary rather than competing goals.
The relationship between zoo welfare and zoo conservation has evolved from tension to integration. Well-cared-for animals in enriched environments are healthier, reproduce more successfully, and better represent natural behavior to educational visitors. Field conservation programs funded by zoos protect habitat and wild populations for the same species in zoo collections. The welfare case for high-quality zoo care and the conservation case are mutually reinforcing.
