The saiga antelope is one of the world's most remarkable conservation stories — both of catastrophic collapse and tentative recovery. Understanding its welfare challenges and conservation needs reveals the complex intersection of disease, climate, and human pressure facing this unique steppe animal.
The 2015 mass mortality event illustrates the catastrophic scale of welfare harm that can occur when disease, environmental conditions, and population concentration intersect. The affected animals — 200,000 saigas dying within two weeks — experienced haemorrhagic septicaemia: internal bleeding, organ failure, and acute systemic collapse. The speed of the die-off meant that many animals died in apparent good condition one day having been dead the next, but many others experienced the progressive deterioration of acute septicaemia before death. The welfare of surviving calves — orphaned by the sudden loss of their mothers — added a second layer of individual suffering. For conservation managers, the 2015 event has driven investment in early warning systems, disease surveillance, and intervention capacity. The saiga's subsequent population recovery demonstrates the resilience possible when conservation efforts are sustained — a hopeful counterpoint to the welfare catastrophe of the die-off.
