Name:
Atriplex gardneri Low Scrub Alliance
Reference:
NatureServe Biotics 2019
Description:
Stands of this alliance have a very sparse to moderately dense cover of dwarf-shrubs that is dominated by <i>Atriplex gardneri</i>. <i>Artemisia tridentata</i> and <i>Picrothamnus desertorum</i> are codominants in some stands. Many other shrubs and dwarf-shrubs may be present, including <i>Atriplex</i> spp., <i>Krascheninnikovia lanata, Sarcobatus vermiculatus, Suaeda</i> spp., and <i>Tetradymia spinosa</i>. The herbaceous layer, if present, may be dominated by graminoids or forbs. Common species include <i>Achnatherum hymenoides, Eriogonum pauciflorum, Leymus salinus, Monolepis nuttalliana, Pascopyrum smithii, Pleuraphis jamesii</i>, or <i>Xylorhiza venusta</i>. This dwarf-shrubland alliance occurs in western Colorado and eastern Utah, Wyoming and Montana. Stands occur on mesas, plateaus, plains, low hills and eroded "badlands." Sites are nearly flat to moderately steep with moderately deep to deep, usually saline, alkaline soils. Soils are typically fine-textured and often have high erosion rates because of poor infiltration and high runoff. The soil surface is often mostly barren.
