The saiga antelope has experienced dramatic population swings driven by poaching and disease. Its partial recovery demonstrates both conservation effectiveness and the welfare cost of inadequate protection.
Saiga welfare at population scale has seen both catastrophic failure and meaningful recovery within a decade. The mass die-off of 2015 represents one of the most severe acute welfare events in wildlife history — hundreds of thousands of animals dying over days from hemorrhagic septicaemia in a context where individual welfare intervention was impossible. At the individual level, poaching welfare harm includes animals that escape with wounds, separation of dependent young from killed mothers, and pack disturbance that affects herd cohesion. Conservation successes — anti-poaching enforcement, community monitoring programs, and international pressure on traditional medicine markets — have reduced killing rates and allowed population recovery. The saiga case demonstrates the dual welfare impact of conservation: protecting wild animal welfare at scale requires treating both conservation and welfare as complementary objectives rather than separate concerns.
