[Wikipedia] Animal Food & Habitat, Ecosystem Threats, Native American Medicinal Use: Sagebrush provides food and habitat for a variety of species, such as sage grouse, pronghorn antelope, grey vireo, pygmy rabbit, and mule deer. Several major threats exist to sagebrush ecosystems, including human settlements, conversion to agricultural land, invasive plant species, and wildfires. Native Americans have used the plant medicinally. It is also useful as firewood. (link added by Mary Ann Machi)
