Utah HMA Stats

Most of the herd management areas in Utah are on the western side of the state.

Here are some statistics for them, developed from individual pages at the BLM web site.

  • Number of HMAs: 18 (one jointly managed with USFS)
  • Total land: 2.7 million acres (mostly public, some private)
  • Total animals: 1911 (mostly horses, some burros, based on upper values of AMLs)
  • Average stocking rate: 1397 acres per animal (0.72 animals per thousand acres)
  • Stocking rate at 3X AML: 466 acres per animal (2.15 animals per thousand acres)

The last figure is offered as an estimate of the current situation, as many of the HMAs have more animals than allowed by the upper end of their AMLs.

Livestock grazing was reported on the Sulphur HMA and presumably occurs on others.

The largest HMA is Cedar Mountain at 411,636 acres, while the smallest is Tilly Creek at 37,006 acres.

Stocking rates vary from 1.5 animals per thousand acres at Range Creek HMA to 0.4 animals per thousand acres at King Top Mountains HMA.

The North Hills HMA is jointly managed with the USFS.
