Madagascar's lemurs are the world's most endangered group of mammals, with over 100 species facing habitat destruction. Individual lemur welfare and population survival are both critically threatened.
Individual lemur welfare suffers acutely in the pet trade. Capture is traumatic, and lemurs in private ownership are typically housed without appropriate social companions, diet, environmental complexity, or veterinary care. Social species like ring-tailed lemurs kept alone experience profound psychological distress. Wild lemurs in degraded habitat face nutritional stress as preferred food trees are lost, and increased predation risk in fragmented forest. Research lemurs in laboratory settings require welfare standards that accommodate their complex social and environmental needs. Conservation interventions that protect habitat directly benefit the welfare of wild lemur populations by preserving the food resources, social stability, and predator-prey dynamics that allow normal lemur life.
