Immunocontraception offers a humane alternative to lethal wildlife population management, with growing evidence of effectiveness in deer, horses, and other overabundant species.
Wildlife contraception programs address population management needs while respecting individual animal welfare. Unlike lethal control, treated animals continue living full lives without the welfare costs of killing or capture-and-transport. The approach is particularly valuable in contexts with strong public opposition to lethal management, where maintaining community support is essential for long-term program success. Scaling immunocontraception remains a significant logistical and funding challenge.
