All wild horses gathered from areas outside the HMA are considered excess and subject to removal. Those wild horses not selected for removal will be released back into the HMA. Removal of excess wild horses will leave wild horse populations in, or close to, compliance with the Record of Decision and Approved Resource Management Plan (RMP) for the Grass Creek Planning Area.
