Immunocontraception provides a humane population management tool for overpopulated wildlife species, avoiding the welfare costs of lethal culling.
Immunocontraception represents a welfare-positive alternative to lethal population management for overpopulated species. The welfare cost of darting for vaccine delivery is brief and limited compared to the extended stress and physical risks of helicopter roundup. Treated animals remain in their home range with established social bonds intact, avoiding the prolonged welfare impacts of captive holding and relocation. For species where overpopulation creates welfare problems through starvation and disease from exceeding habitat carrying capacity, contraception reduces population-level welfare costs while minimizing individual welfare harm.
