Barren Land Categories:

1.2.2.2.1 Bare Exposed Rock: Those ecosystems characterized by areas of bedrock exposure, desert pavement, scarps, talus, slides, volcanic material, rock glaciers, and other accumulations of rock without vegetative cover. This does not include rock exposures in tundra regions. (Definition Source: A Land Use and Land Cover Classification System for Use with Remote Sensing Data)

1.2.2.2.2 Beaches: Those ecosystems along shorelines characterized by smooth sloping accumulations of sand and gravel. The surface is stable inland, but the shoreward part is subject to erosion by wind and water and to deposition in protected areas.

1.2.2.2.3 Dry Salt Flats: Those ecosystems occurring on the flat-floored bottoms of interior desert basins that do not qualify as wetlands. (Definition Source: A Land Use and Land Cover Classification System for Use with Remote Sensing Data)

1.2.2.2.4 Mixed Barren Land: Those regions in which a mixture of barren land features occurs and the dominant land use occupies less than two-thirds of the area. This includes, for example, a desert region where combinations of salt flats, sandy areas, bare rock, surface extraction, and transitional activities could occur in close proximity.
