Name: Atriplex obovata - Atriplex cuneata Scrub Alliance
Reference: NatureServe Biotics 2019
Description: This alliance occurs in the northern Chihuahuan Desert and Colorado Plateau from western Texas, south-central and northwestern New Mexico, and northeastern Arizona. The vegetation is characterized by a sparse to moderately dense dwarf-shrub layer that is dominated or codominated by <i>Atriplex obovata</i>. Some occurrences may have a dense understory of perennial grasses. Shrub associates may include scattered <i>Atriplex confertifolia, Ericameria nauseosa, Isocoma drummondii, Gutierrezia sarothrae, Prosopis glandulosa var. torreyana, Opuntia</i> spp., or <i>Suaeda</i> spp. The herbaceous layer ranges from moderately dense to absent, and is usually dominated by perennial grasses such as <i>Sporobolus airoides</i> and <i>Pleuraphis jamesii</i>. Other associated species may include <i>Achnatherum hymenoides, Bouteloua gracilis, Elymus elymoides</i>, and <i>Sporobolus cryptandrus</i>. Stands are known from mesas, plains, floodplains, valley bottoms, alluvial flats, lower to upper hillslopes, often in a "badlands" landscape. Soils are generally shallow, poorly developed, and alkaline.
