Urban deer populations are expanding in cities across North America and Europe, creating conflicts and welfare challenges that require thoughtful, evidence-based management approaches.
Urban deer management raises fundamental questions about how to balance deer welfare against human safety and ecological integrity. Vehicle collision mortality is the largest source of acute welfare harm for urban deer, causing traumatic injury and death that is frequently prolonged. Lethal culling, while welfare-costly at the individual level, can reduce population-level suffering by preventing starvation and overcrowding. Immunocontraception offers a non-lethal alternative but is logistically demanding and expensive. Regardless of management method, certain actions improve individual deer welfare: wildlife crossing infrastructure reduces collision risk; humane entrapment-and-euthanasia protocols replace inefficient wounding methods; public education reduces harmful supplemental feeding. Chronic wasting disease represents a growing welfare emergency that requires containment through evidence-based management.
