Urban and suburban deer populations create welfare dilemmas through overabundance, vehicle collisions, and disease — and management approaches vary in their welfare implications.
Urban deer welfare involves both the welfare of individual deer and the welfare harms they cause — to themselves (vehicle strikes, disease, starvation in winter), to other wildlife (habitat overgrazing), and to humans (vehicle accidents). Fertility control through PZP immunocontraception offers welfare-superior population management for isolated suburban populations, but is costly and logistically demanding. Lethal culling can be conducted humanely with skilled shooters but carries acute welfare costs. Urban deer welfare planning requires integrating individual animal welfare with population-level management goals and community values.
