The Bureau of Land Management is seeking public comment on a draft Environmental Assessment for a plan that will likely include the capture and removal of at least 481 wild horses from the Confusion Herd Management Area, located in Juab and Millard Counties in Utah.
The BLM says that removing wild horses is needed to improve rangeland health, among other reasons.
The 235,005-acre HMA, about 30 miles north of Garrison, Utah, is home to a BLM-estimated 551 wild horses. The agency-set population target, or Appropriate Management Level, is 70-115 wild horses, or as low as one horse for every 3,357 acres.
By comparison, the BLM has allocated 25,312 Animal Unit Months of forage annually to 11 livestock operators who graze cattle and sheep seasonally on the HMA (an AUM is the amount of forage needed to sustain one cow-calf pair, one horse or five sheep for a month).
The BLM is considering alternatives that include removing wild horses down to 70, then either doing nothing else to control population growth or doing so and then: using sex-ratio skewing (releasing a 60-40% of males to females); implementing fertility control vaccines and intra-uterine devices (IUDs); or surgically sterilizing some mares and stallions.
As a way to humanely manage wild horses on the range and phase out roundups, RTF supports of safe, proven, humane fertility control vaccines, like PZP, which we have used with a 91-98% efficacy rate at our sanctuary and which has enjoyed similar success in other projects.
RTF strongly opposes the surgical sterilization of wild mares. Such surgeries are dangerous, costly
RTF opposes the use of IUDs based on past studies. RTF remains opposed to their use until they are shown to be safe, humane and effective.
We do not advise sex-ratio skewing for wild horses because the management of populations via sex skewing is temporary (populations return to their normal ratios) and healthy populations rely on whatever the norms are in terms of that population’s demographics. Adjusting a population of wild horses to skew for more or less of anything does not attain a natural state for that population, with behavior ramifications that are not yet understood (potential heightened aggression in stallions, for example).
