Wild Saiga Antelope: Mass Mortality and Welfare Crisis

Saiga antelopes have experienced catastrophic mass die-off events — including a 2015 event killing 200,000 in days — linked to climate and bacterial disease.

Key Facts

Saiga antelopes (Saiga tatarica) once numbered in the tens of millions; populations collapsed 95% between 1990 and 2006 from poaching and habitat loss
In May 2015, approximately 200,000 saiga — over 60% of the global population at the time — died within weeks from hemorrhagic septicemia
The 2015 die-off was caused by Pasteurella multocida bacteria that normally lives harmlessly in saiga nasal passages but became virulent under unusual heat and humidity conditions
Saiga aggregate in huge calving herds in spring — making them simultaneously vulnerable to both mass die-offs and efficient poaching
Saiga horns (only males have them) are used in traditional medicine and command high prices, driving targeted poaching of males

Welfare Considerations

Saiga welfare is defined by extremes. Mass die-off events cause deaths that, from individual welfare perspective, are acute and likely rapid — bacterial septicemia progresses quickly. However, the scale — hundreds of thousands of animals — represents an enormous aggregate welfare event. Poaching of males for horns leaves female-skewed populations and often involves leg-hold traps causing severe injury before death. Calving aggregations, while natural, create periods of extreme vulnerability where any pathogen outbreak, extreme weather event, or poaching activity can have catastrophic population-level consequences. The species' dependence on open steppes makes it acutely sensitive to any land use change that fragments migration routes.
