Annual Findings Reports
Press releases are issued annually describing the state of the herd during the reported year. These brief reports typically include the number of horses in the herd, the number of new foals, mortality rates, and the number of horses removed from the island and available for adoption through the Foundation for Shackleford Horses, Inc.
These annual reports can be found on the park's Wildlife Management webpage.
