Saiga Antelope Welfare and Mass Die-Off Events in Central Asia

The saiga antelope suffers catastrophic mass mortality events linked to Pasteurella bacteria, with climate change increasing the frequency and severity of die-offs that kill hundreds of thousands of animals.

Key Facts

A single die-off in 2015 killed over 200,000 saiga — approximately 60% of the world population
Mass die-offs are caused by Pasteurella multocida bacteria that become lethal during specific climatic conditions
High humidity and temperature combinations trigger bacterial virulence in previously benign gut bacteria
The global saiga population has fluctuated dramatically between hundreds of thousands and near-extinction
Saiga are adapted to harsh Central Asian steppe conditions but are vulnerable to novel climate extremes

Welfare Considerations

Saiga mass die-off events cause catastrophic suffering on an almost incomprehensible scale. Affected animals develop haemorrhagic septicaemia causing bleeding from multiple body orifices, and die within hours to days over vast steppe landscapes where intervention is impossible. Calves orphaned during die-off events starve beside their dead mothers. The climate-driven increase in die-off events means this welfare emergency is likely to worsen without action. Conservation efforts to maintain large, contiguous steppe habitats that allow population resilience after die-offs are the primary welfare intervention available.
