Wild Saiga Antelope: Mass Die-offs and Conservation

Saiga antelopes have experienced catastrophic mass mortality events linked to bacteria and climate, making their conservation urgent.

Key Facts

Saigas (Saiga tatarica) declined 95% in the 1990s due to poaching; recovery has been fragile
A 2015 die-off killed 200,000 saigas - 60% of the world population - in just weeks
The die-off was caused by Pasteurella multocida bacteria normally harmless to saigas
Unusually warm, humid weather caused bacterial overgrowth in the saiga respiratory system
Conservation efforts led by the Saiga Conservation Alliance have helped populations begin recovering
Their distinctive inflated noses filter dust and warm air in their harsh steppe habitat
Mass mortality events affect calves most severely as they have less immune experience

Welfare Considerations

Mass die-off events represent catastrophic welfare events where hundreds of thousands of animals suffer acute severe illness within days. Hemorrhagic septicemia causes rapid systemic failure. For surviving animals, the social disruption of losing a large proportion of the herd causes stress and may affect reproductive success. Climate change increases frequency of the temperature-humidity conditions that trigger bacterial blooms, making future mass die-offs more likely.

What You Can Do

Support the Saiga Conservation Alliance's monitoring and protection programs
Advocate for protection of saiga migration corridors from roads and fences that fragment populations
Oppose illegal trade in saiga horns which funds poaching pressure
Support climate research that helps predict and prepare for conditions triggering mass die-offs
Donate to veterinary response capacity in range countries for mass mortality events
Learn about saiga ecology and share awareness of this unusual and threatened species
