Saiga antelopes experienced catastrophic population collapses from disease and poaching. Their recovery story offers lessons about herd dynamics, welfare, and conservation intervention.
Saiga mass die-off events cause suffering at a scale that challenges comprehension — hundreds of thousands of animals dying within days from acute septicaemia. Individual animals experience fever, respiratory distress, and systemic organ failure. The 2015 event left calves orphaned at a critical developmental stage. Recovery between events is encouraging but fragile — poaching pressure can rapidly undo population gains. Climate change creates ongoing risk of repeated mass mortality events, meaning this species faces a permanent threat to both population viability and individual welfare from environmental conditions that trigger bacterial virulence. Understanding these mass mortality events is essential both for conservation and for the welfare of individual animals during future events.
