Saiga antelopes have experienced catastrophic population crashes from poaching and disease. Conservation efforts for this ancient Ice Age survivor illustrate both the severity and the tractability of wildlife welfare crises.
Saiga welfare at population level has experienced some of the most dramatic swings documented in wildlife conservation. The 2015 mass mortality event — caused by Pasteurella multocida bacteria in conditions of unusual humidity linked to climate change — saw hundreds of thousands of animals die rapidly in what field researchers described as a scene of extraordinary suffering across the steppe. Individual welfare during such events is impossible to address but underscores the catastrophic risk of climate and disease stressors on wild populations. Poaching welfare impacts include animals dying from wounds, trauma, and abandonment of dependent young. Conservation programs addressing these threats — anti-poaching patrols, traditional medicine market pressure, and habitat protection — simultaneously improve welfare and conservation outcomes. The saiga recovery demonstrates that conservation efforts can achieve rapid population rebounds when threats are addressed effectively.
