Deer populations are expanding into suburban and urban areas, creating welfare challenges from traffic, disease and human habituation. Managing urban deer humanely requires evidence-based approaches.
Urban deer welfare involves a complex mix of direct welfare harms and management challenges. Traffic mortality causes sudden death or severe injury in deer; CWD causes a prolonged, distressing neurological decline; and habituation removes the fear responses that enable deer to avoid human threats. Management dilemmas include the tension between lethal culling (rapid but ethically contentious) and fertility control (humane but slow and resource-intensive). Community attitudes toward urban deer are polarised between those who value their presence and those who experience them as a nuisance, complicating management decisions. The most welfare-positive approach integrates habitat management to discourage deer from high-traffic areas, fertility control where feasible and humane lethal management targeting welfare-compromised individuals where necessary.
