Southwest Desert, South, Utah

Basin-and-range topography with broad desert valleys flanked by north-south-trending mountain ranges. Elevations span roughly 5,200 feet on the valley floors to approximately 9,765 feet at the summit of Indian Peak (highest point in the unit), with ridgelines of the Wah Wah Mountains and associated ranges reaching 8,000–8,600 ft. Valley floors are flat to gently rolling; mountain slopes are rocky and rugged. No National Forest land exists within the herd unit — terrain is entirely BLM, state trust, or private.

The boundary is served by two primary north-south corridor roads: Hamlin Valley Road on the western side and Pine Valley Road on the eastern side, both unpaved BLM roads traversing the basin. SR-21 forms the northern boundary of the South sub-unit (Milford-Nevada corridor), SR-130 and I-15 the eastern boundary, and SR-56/Lund Highway the southern boundary. Interior access requires high-clearance or 4WD vehicles; some roads are 30 miles from the nearest town. Year-long land ownership is approximately 95% BLM (Cedar City Field Office administers Iron and Beaver counties; Fillmore Field Office covers Millard County portions), with Utah State Institutional Trust Lands making up roughly 5% and private land under 1%. No National Forest lands are present. The Indian Peak Wildlife Management Area (UDWR) is located within the unit. Wild horse activity is significant across the unit, and feral horses have been documented at many springs and water sources. No designated wilderness areas are known within this boundary, but roadless terrain is extensive.

Winter range consists predominantly of big sagebrush (mountain big sagebrush on deeper soils, black sagebrush on shallow sites) with pinyon-juniper at the edges; winter range elevations run 5,200–8,000 ft. Summer range in the Indian Peak Range and Wah Wah Mountains supports mixed mountain brush, aspen/conifer communities, and curlleaf mountain mahogany on rocky upper-elevation sites. Approximately 20.84% of the unit is mapped as pinyon-juniper woodland (Landfire model), which encroaches into sagebrush communities. Exotic annual grass (cheatgrass) covers roughly 3.99% of the unit, concentrated on lower-elevation sites. Riparian corridors are limited; springs, ponds, and developed wildlife guzzlers are critical water sources across the arid basin.

Mule deer are the primary big game ungulate; the herd unit 2019 post-season population estimate was approximately 3,000 deer with a 10-year average of 2,440, managed as a general-season unit targeting 18–20 bucks per 100 does post-season. Elk have expanded significantly over the past 25 years, with a unit-wide population objective of 1,050–1,250; bulls using the South unit are managed for a 3-year average harvest age of 6.0–6.5 years — among the higher bull-age objectives in the state. Pronghorn occupy the open desert flats and basin grasslands. Mountain lion and black bear may be present given the mountain brush and juniper habitats. Wild horses are a documented management challenge throughout the unit, competing with deer and elk for forage and water; 3,585+ horses were removed 2016–2022 and ongoing gathers continue. Greater sage-grouse also use the sagebrush rangelands. GPS collar data has documented cross-border elk migration from Nevada into the unit during winter, which can inflate wintering population counts.

1. BOUNDARY SUBDIVISION: The North/South split applies only to elk. The deer general-season boundary (DB1524/DB1554/DB1584) and pronghorn boundary (PB5018/PB5049/PB5024) cover the combined Southwest Desert herd unit #20, not just the southern sub-area. 2. ELK PERMIT QUOTAS: 2026 Application Guidebook confirms Southwest Desert, South has limited-entry elk hunts across all weapons/dates, but individual permit quotas per hunt code are not published; 2024 actual permit counts are used instead. 3. PUBLIC LAND PCT: The deer plan reports 95% BLM for year-long range and 84% for summer range; GoHunt reports 90% overall. The 90% figure is used as the best single approximation. 4. GENERAL DEER SUCCESS: General-season (OTC) deer success rates for this unit are not in the LE harvest report; a separate general-season deer report would be needed. 5. MOUNTAIN LION / BLACK BEAR: Both species are present in Utah and the mountain-brush/pinyon terrain of the Wah Wah and Indian Peak ranges is suitable habitat, but no unit-specific harvest data was sourced. 6. WILD HORSES: Feral horses are a significant factor — UDWR documents heavy horse occupancy at water sources and major grazing pressure across BLM allotments; 3,585+ horses were removed 2016–2022 and ongoing gathers are part of the management plan. 7. NEVADA ELK MIGRATION: GPS collar data confirms winter migration of elk from Nevada into this unit, which can inflate wintering population counts (confirmed in 2023 elk plan). 8. ELEVATION CORRECTION: Indian Peak is the highest point in the unit at 9,765 ft (per deer plan); the Wah Wah and associated ridgelines reach 8,000–8,600 ft. 9. ELK MUZZLELOADER CORRECTION: Season is Sept. 21–Oct. 2 (EB3155, confirmed 2026 app guidebook); draft had Sept. 23–Oct. 1 which was incorrect.
