B30 New Mexico Saltbush Badl<strong>and</strong> Sparse <strong>Vegetation</strong><br />
Location: New Mexico Saltbush Sparse <strong>Vegetation</strong> was a very common map class. It was characteristically<br />
found on bentonite clay soils in the badl<strong>and</strong>s, but it occurred throughout the entire project boundary.<br />
Photosignature: This map class was often the default map class assigned to the vegetated badl<strong>and</strong>s in<br />
the project boundary. It occurred on all of the various badl<strong>and</strong> soils <strong>and</strong> occurred throughout the project<br />
boundary. The vegetation cover ranged from a low to moderate cover. In most areas, the vegetation was<br />
not easily identified due to its sparseness <strong>and</strong> the strong soil signature masking the vegetation. In some<br />
areas Atriplex obovata appeared as small specks with large spaces between plants <strong>and</strong> a light greenish/<br />
gray color.<br />
