Range (also known as range lands) is a barren land that is not fit for agriculture and cultivation. Range land is mainly utilized as a source of continuous forage for cattle. Ranges can also provide natural resources like minerals and timber. Also these can be utilized as spaces for recreation and enjoyment. An ideal range land should provide almost all of the above-mentioned utilities. It should act as a source of foliage for domestic and other types of animals; it should provide natural resources; also it should have the facilities to be converted as a park or any other recreational spot. For making a range land ideal for all these purposes, a stream of science has emerged. It is called the management of range ecology. Generally the management of range ecology is associated with environment and agriculture.

Montana State University, University of Idaho, Oregon State University, Colorado State University, Texas A and M University are some of the major universities in United States that provide excellent bachelor-level and post-graduate courses in range management.
