With no natural predators, UK deer populations have expanded substantially, creating welfare and ecological challenges that require active management.
Deer injured in road collisions may lie suffering for hours before being found or euthanized. Poorly executed shots from stalking leave wounded animals that flee and die slowly. Overpopulated herds face malnutrition and disease in winter when vegetation is depleted. The absence of natural predators means deer populations require human management, but the welfare quality of that management varies enormously between practitioners.
