BLM Jarbidge Field Office releases wild horses to Saylor Creek Herd Management Area

TWIN FALLS, Idaho – Today, the Bureau of Land Management (BLM) Jarbidge Field Office, Twin Falls District released 11 wild horses (six studs, five mares) to the Saylor Creek Wild Horse Herd Management Area (HMA), 15 miles south of Glenns Ferry. 

Earlier this year, the Jarbidge Field Office conducted a water/bait trap gather of the Saylor Creek HMA wild horse herd to reduce the overpopulation on the range, capturing 104 horses. Many of these horses will be offered for adoption later.  

This release will bring the Saylor Creek wild horse population to its Appropriate Management Level of 50. The mares to be released have been treated with the fertility control vaccine GonaCon Equine, one of the vaccines the BLM uses in its management of wild horses on the range. It can cause high rates of contraception that can last two to five years.

The BLM manages more than 245 million acres of public land located primarily in the 11 Western states and Alaska. The BLM also administers 700 million acres of sub-surface mineral estate throughout the nation. In fiscal year 2018, the diverse activities authorized on BLM-managed lands generated $105 billion in economic output across the country. This economic activity supported 471,000 jobs and contributed substantial revenue to the U.S. Treasury and state governments, mostly through royalties on minerals.
