Description
Range is the dominant land use for this site and provides the most diverse ecosystem services. Range is land on which the historic and/or introduced vegetation is predominantly grasses, grass-like plants, forbs or shrubs managed as a natural ecosystem. Range may include natural grasslands, savannas, shrublands, tundra, alpine communities, marshes and meadows.
Characteristics and indicators
This landuse consists of diverse native plant communities dominated by black sagebrush and perennial cool season grasses that provide for site stability, hydrologic function, and biotic integrity of the site.

Description
Land that is barren, sandy, rocky, or that is impacted by the extraction of natural
resources, such as minerals, gravel or sand, coal, shale, rock, oil, or natural gas.
Characteristics and indicators
This land use can be many things, but in this LRU is most often associated with oil and gas development.
Barren land. A land cover/use category used to classify lands with limited capacity to support life and having less than 5 percent vegetative cover. Vegetation, if present, is widely spaced. [NRI-87]
Typically, the surface of barren land is sand, rock, exposed subsoil, or salt-affected soils. Subcategories include salt flats; sand dunes; mud flats; beaches; bare exposed rock; quarries, strip mines, gravel pits, and borrow pits; river wash; oil wasteland; mixed barren lands; and other barren land. [NRI-92]

Mechanism
The conversion from Range to Other - Mineral Extraction Lands occurs when vegetation and soil is manipulated for the purpose of mineral extraction. Common practices are oil and natural gas pad and pipeline infrastructure, gravel pits, and road construction. Vegetation and topsoil is removed and topsoil is often stockpiled for on or off-site reclamation.
Mechanism
Conversion from Other - Mineral Extraction Lands to Range occurs, sometimes over a long period of time, as part of the restoration process after mineral extraction. There is low potential for recovery without significant inputs of energy and resources, especially if topsoil has been removed.
Seed mixes that mimic an adjacent “reference area” rather than the site potential as described in the Reference State (1.1) will often result in a plant community resembling the Grazing Resistant State (1.2) due to inappropriate seed mixes and pre- and post-seeding grazing management that does not provide adequate recovery and periodic critical growth period rest.
