Appendix C: Global and local plant community descriptions C.5 Sparse C.5.1. Atriplex obovata Badland Sparse Vegetation Base map class NatureServe common name NatureServe code New.Mexico.Saltbush.Badlands.Sparse.Vegetation New.Mexico.Saltbush.Badland.Sparse.Vegetation CEGL002928 Summary: This sparsely vegetated badland association occurs in the southern Colorado Plateau in northern Arizona between the elevations of 1300 and 1741 m (4265-5712 ft). Sites are flat to gently sloping and range between 0 and 9% (average 3%). Substrates are clays derived from shale. Many of the stands have some cover of surface rocks, including sandstone, basalt, desert pavement, and petrified wood. The vegetation cover is characterized by sparse total vegetation cover (
Vegetation Classification and Distribution Mapping Report: Petrified Forest National Park Distribution: Globally. This association is currently known from Arizona. Petrified Forest National Park. Atriplex obovata Badland Sparse Vegetation was identified from twelve relevés and occurred mostly on plateaus and sand dunes/sandsheets within Petrified Forest National Park. A few relevés were located near or in a drainage channel, on a flat plain, or in an area with talus. This association ranged the entire extent of the project boundary, including the northern wilderness area between Wildhorse Wash and Lithodendron Wash, south of Lithodendron Wash and north of Chinde Point, north of Old Route 66 and northwest of Alley Way Tank, southwest of Blue Mesa, northeast of The Flattops, east of Dry Wash and Agate Bridge, east of The Haystacks, south of Cottonwood Wash, and northwest of the Crystal Forest. Environmental summary: Globally. This sparsely vegetated badland association occurs in the southern Colorado Plateau in northern Arizona between the elevations of 1300 and 1741 m (4265-5712 ft). Sites are flat to gently sloping and range between 0 and 9% (average 3%). Substrates are clays derived from shale. Many of the stands have some cover of surface rocks, including sandstone, basalt, desert pavement, and petrified wood (Hansen et al. 2004b). Petrified Forest National Park. This association occurred between the elevations of 1630 and 1741 m (5348-5712 ft) with no or a low slope ranging between 0 and 9% (average 3%). Many of the stands have some cover of surface rocks, including sandstone, basalt, desert pavement, and petrified wood. USFWS wetland system: Not applicable. Vegetation description: Globally. The vegetation is characterized by sparse total cover (
