Saiga antelopes experienced catastrophic die-offs from a bacterial disease linked to climate anomalies. Understanding this welfare disaster informs conservation responses.
The 2015 saiga mass die-off represents one of the largest acute wildlife welfare disasters in recorded history. Animals experiencing bacterial septicemia suffer fever, convulsions, and rapid death over 1-3 days. The massive scale — hundreds of thousands of animals dying simultaneously — was overwhelming for any response capacity. Climate change is increasing the frequency and severity of conditions that trigger such events, making mass die-offs a growing wildlife welfare concern. Population resilience through habitat protection and anti-poaching creates the buffer needed to absorb such events.
