Approximately 600 animals will be removed from the Sulphur HMA beginning August 15, according to a BLM news release issued today.
The operation, to be carried out with helicopters, will be open to public observation.
The HMA covers 265,711 acres in western Utah and has an AML of 250, for an aimed-at stocking rate of 0.9 horses per thousand acres.
The announcement did not refer to the NEPA project that authorized the roundup, but this one, initiated in 2015, may be relevant.
Table 3.2 in the Final Environmental Assessment indicates that the HMA intersects nine grazing allotments. The total estimated forage available to livestock inside the HMA is 10,256 AUMs per year, compared to 3,000 AUMs per year for the horses.
The current population of 1,193 horses would consume 14,316 AUMs per year.
Captured animals will be taken to the off-range corrals in Axtell, UT.

Why is BLM at the Border Inn today Aug 11 if the capture is Aug 15, and why are use helicopters when water trapping is available at the primary water sources? The non Sulphur types that have been integrated into this herd have diluted their cultural historic and rare dna without the mandated consultation/coordination with resource management plans. This herd may be better managed under local volunteer partnerships. Horses at Needle Point (pictured below )is inconsistent with conformation from the original Sulphurs whose DNA is on file with Dr. Cothran. This inconsistency is NOT a result of distinct population segment or remnant population of natural evolution. This rare herd has been an integral cultural resource since 1840 and should be managed as such. I was with Gus Warr on the 2008 Sulphur capture which was staged at Ladd Davies Burbank Ranch and contracted for 13 proto typed mares to replace the Coyote Canyon foundation mares which were delivered to Coyote Canyon Heritage Herd in 2009.
