Name: Atriplex confertifolia - Picrothamnus desertorum Shrubland Reference: NatureServe Biotics 2019 Description: This alkaline desert association occurs in the Great Basin, Mojave Desert, Columbia Basin and Colorado Plateau and is likely more widespread in the intermountain western U.S. It occurs on barren toeslopes and playas on sandy or heavy clay soils, and foothill areas where saline hardpans occur at depths of 30-60 cm (1-2 feet). The shrubs are low-statured and open, often with very low cover (5-15%). Dominant shrubs are <i>Atriplex confertifolia</i> and <i>Picrothamnus desertorum</i>. Other shrubs, such as <i>Artemisia tridentata</i> and <i>Sarcobatus vermiculatus</i> in Nevada, and <i>Coleogyne ramosissima, Gutierrezia sarothrae</i>, and <i>Tetradymia spinosa</i> in southern Utah, may be present to codominant. Herbaceous cover is generally very sparse, due to overgrazing or lack of moisture. Graminoids include <i>Achnatherum hymenoides, Pleuraphis jamesii, Poa secunda</i>, and <i>Sporobolus airoides</i>; common forbs include <i>Calochortus nuttallii, Cymopterus newberryi, Encelia nutans</i>, and <i>Sphaeralcea coccinea</i>. The annual invasive grass <i>Bromus tectorum</i> can be abundant, but its presence is variable year to year.  Accession Code: urn:lsid:vegbank.org:commConcept:30204-{0B18680C-E968-46F6-B74B-9154AFA3F44C} Plot-observations of this Community Concept: 0
