The park has received additional questions about naming of horses, current partnership status, and individuals posting information in electronic formats. There has been no change in park policy since launching of the FAQ in September, 2020. FAQs #1, #3, and #4 still represent the park's position on these topics. A new question about pedigrees and genetics has also arisen. Please see FAQ #16 in response to that inquiry.

To reduce foaling rates and minimize the number of animals that must be captured and sold annually to manage the demonstration herd size, Theodore Roosevelt National Park is administering GonaCon™ Equine immuno-contraceptive vaccine to all female horses ≥8 months of age. Contraceptives will be administered remotely by syringe dart, providing approximately two years of fertility control. The vaccine does not impact current pregnancies. Operations are planned to start in September of 2020 and be completed by December of 2021.

Most reproductive age female horses in the park have already received contraception as part of a study. Results of that research indicated that the vaccine is effective but temporary. This temporary fertility control will provide latitude as the park explores development of a new comprehensive herd management plan.

The vaccination does not preclude subsequent transfer of animals out of the park. Therefore, capture and auction operations will continue to provide ownership opportunities for interested parties.
