Wildlife management of big game such as deer and elk and vegetation management are coordinated with the Colorado Parks and Wildlife local office. 


The Greater Sage-grouse, also known as the sagehen, is the largest grouse  in North America.  This bird is a permanent resident in its breeding grounds but may move short distances to lower elevations during the winter. It makes use of a complex lek system in mating and nests on the ground under sagebrush or grass patches. It forages on the ground, mainly eating sagebrush but also other plants and insects. Greater sage-grouse do not have a muscular crop and are not able to digest hard seeds like other grouse.

The species is in decline across its range due to habitat loss, and has been recognized as threatened or near threatened by several national and international organizations.

The BLM must also protect the two plants listed on the Endangered Species Act, as well as the five BLM designated sensitive plant species within the Herd Management Area. Sensitive plants are especially vulnerable during the flowering season, late April to early August.
