The county has just two incorporated cities: Burns, the county seat and larger city, with 40 percent of the population, and Hines, with 20 percent of the county's population. About 75 percent of the county's area is federal land, variously managed by the Bureau of Reclamation, Bureau of Land Management, U.S. Fish and Wildlife Service, and U.S. Forest Service. About 10 percent of Harney County's area is part of the Ochoco National Forest and Malheur National Forest. The county also contains the Burns Paiute Indian Reservation within and immediately north of the City of Burns; this 760-acres reservation of the Burns Paiute Tribe is a remnant of the former Malheur Indian Reservation, a 1.5-million-acre federal trust land that was encroached upon by white settlement in the 19th century. Harney County has a \"high desert\" topography, with low levels of precipitation.
