Red Hill Elk Herd Management

Boulder County manages the Red Hill elk herd located on either side of US 36 between Heil Valley Ranch and Table Mountain using limited hunting and other resource management tools.

2021-2022 Hunting Season

The Red Hill elk management hunt is intended to target a growing resident herd and will occur from Aug. 16 through Oct. 30. Three selected hunters will be permitted each week from Monday through Saturday. Although the hunting area is closed to the public, given its proximity to trails and residential housing, only short-range methods of take will be allowed. These include archery (west of US 36 only), muzzleloader, and shotgun slug. Learn more about hunting on open space.

This hunting program is solely and specifically permitted as a resource management tool. There is no cost to the hunter beyond the existing Colorado Parks and Wildlife license system and Boulder County does not receive any additional revenue. Recreational hunting in the management area or any other open space property is strictly prohibited.

Updates will be posted in the fall.

2020-2021 Implementation

  • Hunting at Red Hill concluded on Saturday, Nov. 7. The season was extended by one week to accommodate the cancellation of hunting during the week of Oct. 19 due to the Cal-Wood Fire. Hunting during the final two weeks of the hunt was therefore restricted to areas east of US 36.

  • CPW completed several shooting proficiency tests with multiple methods of take, including archery, muzzleloader, and shotgun. Rifles were not permitted.

    • 5 harvests at Red Hill East
    • 2 harvests at Imel
  • 35% success

The Red Hill elk herd makes use of county-owned properties closed to the public on either side of US 36 between Heil Valley Ranch and Table Mountain. The area has been historically utilized by the herd during fall and winter after migrating down from its summer range at higher elevations. However, a growing number of elk has recently stopped migrating and now spends the summer summer at low elevation on county-owned properties and the Table Mountain area. The use of the Table Mountain area is a new development altogether, occurring only within the last 10 years. Three formal summer counts in 2019 all counted more than 88 elk, including a large segment of calves. This growing elk population has come into conflict with neighbors and Parks & Open Space agricultural tenants both north and south of Nelson Road. Additionally, this area has been noted as a dangerous highway elk crossing by the Colorado Department of Transportation with numerous vehicle-wildlife collisions.

The elk herd’s rapid population growth has the potential to cause extensive damage to the highly diverse native plants and wildlife habitat of this area. According to the Colorado Natural Heritage Program, portions of this area are rated B1 Outstanding Biodiversity Significance, which means the plant and wildlife diversity is globally rare and irreplaceable and other areas as B2 (Very High Biodiversity Significance). This area is also designated as a Critical Wildlife Habitat and an Environmental Conservation Area in addition to being a Natural Area (#9, Red Hill) in the Boulder County Comprehensive Plan Environmental Resources Element.
