It consists of a sampling area of 68 km2 (15,300 acres) and is managed by the Bureau of Land Management. It is characterized by the sagebrush and western juniper community that dominates the Great Basin. The site is part of NEON's Great Basin Domain (D15), which is bordered by the Sierra Nevada to the west, the Rocky Mountains and Colorado Plateau to the east, the Mojave Desert to the south, and the Columbia Plateau to the north. D15 has one other field site, the aquatic site REDB.
