"In order to manage for healthy horses on healthy rangelands, I have made the decision to use fertility control vaccine on all mares 11 years of age and older (24 mares in 2006) on the Pryor Mountain Wild Horse Range (PMWHR). Seven mares 16 years of age and older have already been treated with the Porcine Zona Pellucida (PZP) vaccine and would continue to receive annual boosters for the remainder of their lives. Thirteen mares 12-15 years of age have also been treated and would continue to receive annual boosters throughout 2010. All mares that are 11 years of age would be added to the treatment program each year. Fertility control applications are scheduled to begin no earlier then July 10th, 2006, and may continue through September 30th, 2006."

"In addition, I have made the decision to capture and remove a maximum of 22 age-specific wild horses from the PMWHR. An estimated 11 bachelor stallions (4-8 years of age ) and 11 yearlings have been determined excess and would be removed due to the need to reduce wild horse grazing impacts on the PMWHR. The method of capture will be bait-trapping which is scheduled to begin no earlier than July 10th, 2006, and may continue through September 30th, 2006."
