2024 Sulphur Herd Management Area Wild Horse Gather

The BLM Cedar City Field Office began gather operations to remove wild horses from within and outside of the Sulphur Herd Management Area in Beaver, Iron and Millard Counties on Tuesday, Aug. 13. Gather operations concluded on Friday, Aug. 23.

Purpose of Gather:

The gather will help balance the number of horses to what the rangeland can sustainably support, known as the appropriate management level (AML). The AML within the Sulphur HMA is 165 to 250 animals; the current population is estimated at 606 wild horses.

Details of Gather:

Gather operations will begin on Tuesday, August 13, 2024.  The BLM will gather approximately 420 wild horses from BLM-administered lands using the helicopter drive-trapping method. Population growth suppression will be administered to selected mares to help stabilize the annual increase of animals being born on the HMA. Horses removed from the range will be transported to the Axtell Off-Range Contract Wild Horse Facility in Axtell, Utah.

The gather was expected to last approximately 14 days and concluded after 10 days.

Public Observation:

Opportunities are available for the public to observe daily gather operations through BLM-escorted tours, so long as conditions remain safe for both the horses and participants and gather operations are not disrupted. Observers must provide their own transportation, water, and food. No public restrooms will be available. The BLM recommends weather-appropriate footwear and neutral-colored clothing. Binoculars and four-wheel drive or other high-clearance vehicles are also strongly recommended. 

Details on the BLM-escorted tours will be updated each evening during the gather and announced daily on the BLM gather hotline at 801-539-4050.

Adoption Information:

All excess wild horses identified for removal will be transported to the Axtell Off-Range Contract Wild Horse Facility in Axtell, Utah, where they will be checked by a veterinarian and readied for the BLM’s wild horse and burro Adoption and Sale Program. Those that are not placed into a new home will be cared for in off-range pastures, where they live off the rest of their lives on grass pastures.

Background:

In the mountain peaks and sloping lowlands of western Utah roams a nationally recognized population of wild horses with a Utah heritage much older than most of ours. Many of these horses draw their bloodlines from the old Spanish Type, the Colonial Spanish Horse, the first horses brought to America by the Spanish Explorers in the 1500s. Through time, the Sulphur Herd has bred with escaped ranch livestock, but some still hold many of the Colonial Spanish Horse traits. These traits include colors that are dun and grulla, a gray or mouse color. Their ears can curve in like a bird's beak, with fawn-colored insides rimmed in black. They may have a dorsal stripe down their back, bi-colored manes and tails, and striped legs.   Some may even have some facial cob webbing or a mask on their face. The horses have a short back, because they may have only five lumbar vertebrae instead of six. There are only a few other herds of wild horses in the United States which may exhibit these same characteristics. 

Location

The HMA is located in western Iron, Beaver, and Millard counties. Approximately 50 miles west of Minersville, Utah in the Indian Peak and Mountain Home Mountain Ranges). The elevation ranges from 9,790 feet on top of Indian Peak to 6,000 feet in the valley floors. 

Size

The HMA contains 230,157 acres of BLM lands and 35,554 acres of Federal, State-, and privately-owned land for a total of 265,711 acres. 

Topography/Vegetation

The Sulphur HMA supports multiple vegetation types including Aspen, Mountain Fir, Spruce-Fur, Mountain Shrub, Pinyon-Juniper (PJ), sagebrush, grasslands, and salt desert shrub. The PJ woodland type dominates the HMA and is very dense with minimal understory forage. Open areas outside the PJ canopy are dominated by big sagebrush with Indian ricegrass, wheatgrass, bluegrass, and squirreltail grass as the primary forage species. Available water within the HMA is the limiting factor regarding these horse populations. Water is limited to isolated springs and man-made developments that supply water to permitted livestock, wildlife, and wild horses. 

Available water within the HMA is the limiting factor regarding this HMA.  Water is limited to isolated springs and man-made developments that supply water to permitted livestock, wildlife and wild horses. Several springs primarily used by wild horses were dry during the summers of 2000-2004, 2007-2008, and 2012-2015, forcing animals onto winter ranges and into areas outside of the HMA traditionally unoccupied by horses. Most water sources produced less than average levels for the summer, forcing wild horses to use winter ranges throughout the summer. 

Wildlife

Big game species that occur in the Sulphur HMA include mule deer, Rocky Mountain elk and pronghorn. All three species are year-long residents. Competition for forage between big game species and wild horses is greatest during the spring and summer months when mule deer, elk and pronghorn are feeding primarily on grasses and forbs. Additionally, forb consumption is crucial during the early spring months for does to maintain a healthy body condition while meeting the nutrient requirements of nursing fawns. Competition is reduced in fall and winter when mule deer and pronghorn shift their diets to browse (i.e. bitterbrush, sagebrush) species. Typically, elk move to wintering areas throughout the Pine and Hamlin Valleys. During periods of drought competition between wildlife and wild horses increase dramatically when less forage is available.
