The common vole is a keystone prey species supporting raptors and predators across European farmland, and its welfare and population health are critical to ecosystem function.
Mass rodenticide campaigns against vole populations cause widespread welfare suffering and remove the prey base for raptors and predators. Harvest machinery kills large numbers of voles during summer cropping. Loss of refugia in field margins reduces survival during winter and predation pressure periods. Welfare priorities include minimising rodenticide use and retaining rough grassland habitats.
