BLM Concludes Swasey Wild Horse Catch, Treat, Release and Removal Gather

Fillmore, Utah—The Bureau of Land Management (BLM) West Desert District, Fillmore Field Office concluded the Swasey Herd Management Area (HMA) wild horse gather on Saturday, February 16, 2013.  The BLM successfully removed 160 wild horses from the Swasey Herd Management Area (HMA), 97 were released back onto the Swasey HMA, and Porcine Zona Pellucida, (PZP-22), a two-year fertility control vaccine, was applied to 44 mares prior to release.  Of the 257 wild horses gathered, there were no injuries or deaths that occurred during the five-day gather operation.

The Swasey HMA is located in Millard and Juab Counties 50 miles west of Delta, Utah, and encompasses approximately 120,113 acres, with an Appropriate Management Level, or AML of 60-100 wild horses.  This was the initial gather in a 10-year phased approach to achieve AML and to reduce overall population growth by applying fertility control to mares.  While this initial gather does not achieve the low end of AML, the target removal number for this gather was reached and the BLM plans to return for two to three follow-up gathers to reach low AML and implement population controls over a period of 10 years contingent upon funding and holding space.  It is estimated that approximately 160 wild horses currently reside on the HMA.  BLM specialist will continue to monitor the horses and habitat to ensure the long-term survival and sustainability of the population.

Animals removed from the Swasey HMA were transported to the Delta Wild Horse and Burro Facility and will be available for adoption through the BLM Wild Horse and Burro Adoption Program.  Those that are not adopted will be cared for in long-term pastures, where they retain their “wild” status and protection under the 1971 Wild Free-Roaming Horses and Burros Act. 

The gather began on February 12, 2013 and concluded on February 16, 2013.  An Animal and Plant Health Inspection Service veterinarian was on site daily to evaluate animal conditions and provide recommendations to the on-site BLM wild horse and burro specialist for care and treatment.  BLM staff utilized the Henneke body condition scale to classify gathered wild horses. On a scale from one to nine (one being poor condition and nine being extremely fat), Swasey horses were generally a body condition score of three, with a few wild horses observed to be higher or lower.
