The "Veterans for Mustangs Act" amends the Wild Free-Roaming Horses and Burros Act, directing the Secretary of the Interior to immediately implement humane, reversible, non-surgical, immunocontraceptive vaccine fertility controls to manage wild horse and burro populations. This new approach prioritizes on-range fertility management as a primary method for achieving appropriate population levels. A significant aspect of the bill is its focus on military veterans , encouraging their recruitment, training, and certification in applying these fertility controls. The Secretary is authorized to compensate veterans for this training and to contract with certified veterans to perform range management activities, ensuring they are not considered federal employees through such contracts.
