Saiga antelope habitat restoration across Central Asian steppes addresses the root causes of population vulnerability that contribute to mass mortality welfare events.
Habitat fragmentation creates welfare consequences for saiga by preventing access to the resource patches needed across their annual migratory cycle. Fences that block migration routes to calving grounds cause physiological stress in pregnant females that cannot access optimal calving habitat. Barrier removal and corridor creation represents a welfare intervention with large-scale impact because it restores the natural behavior and nutritional access that hundreds of thousands of animals depend on. Connectivity restoration also reduces the density-dependent stress and competition that contributes to vulnerability during mass mortality events. Long-term habitat restoration is therefore both a conservation and a welfare investment.
