The Mixed Barren Land category is used when a mixture of Barren Land features occurs and the dominant land use occupies less than two-thirds of the area. Such a situation arises, for example, in a desert region where combinations of salt flats, sandy areas, bare rock, surface extraction, and transitional activities could occur in close proximity and in areal extent too small for each to be included at mapping scale. It also occurs in military bases when there is a mixture of Transitional Bare Area and other barren land types. Where more than one-third intermixture of another use or uses occurs in a specific area, it is classified as Mixed Barren Land. Where the intermixed land use or uses total less than one-third of the specific area, the category appropriate to the dominant type of Barren Land is applied.
DISTRIBUTION:
This type occurs throughout California.
