UK deer populations have reached record numbers with no natural predators, creating vehicle collisions, habitat damage, and welfare challenges requiring active population management.
UK deer welfare is paradoxically challenged by their population success. High densities increase competition for food, spread disease, and result in higher road mortality. The absence of wolves and other natural predators means human culling is the welfare-appropriate alternative to starvation and disease. Welfare during culling depends entirely on marksmanship standards - clean shots result in rapid death; poor shots cause suffering. Vehicle collisions cause significant suffering and require better infrastructure mitigation. Reintroduction of large predators would address some welfare concerns but raises its own complex questions.
