Immunocontraception and other non-lethal methods of wildlife population management offer welfare-superior alternatives to lethal culling for managing overabundant wildlife populations.
Wild animal contraception offers a welfare-superior approach to population management by avoiding the mortality, injury, and stress of lethal control. Individual animals experience a dart injection rather than hunting or trapping, and can continue living in their social groups and familiar territories. The welfare case for contraception is compelling where it is logistically feasible — primarily in smaller, contained populations or urban settings where individual tracking is practical. Its limitations — cost, the need for repeated treatment, and failure to immediately reduce populations — mean it is a complement to rather than universal replacement for other management approaches.
