Name: Atriplex gardneri - Picrothamnus desertorum Dwarf-shrubland Reference: NatureServe Biotics 2019 Description: This dwarf-shrubland occurs on broad alluvial plains in the Big Horn Basin and Pryor mountains of Montana and possibly Wyoming. Elevation ranges from 1400-1460 m. Stands are restricted to arid climatic regimes and moderately alkaline, poorly drained soils derived from the Chugwater sandstone. Soils are very deep, poorly developed clays derived from alluvium. This association typically has a moderately dense dwarf-shrub canopy (58% mean cover) that is codominated by <i>Atriplex gardneri</i> and <i>Picrothamnus desertorum</i>. <i>Krascheninnikovia lanata</i> is common in some stands, and <i>Artemisia tridentata</i> is often present. Herbaceous cover is very sparse (&lt;10% cover) and may include the grasses <i>Poa secunda, Elymus elymoides, Achnatherum hymenoides, Bouteloua gracilis, Sporobolus cryptandrus</i>, scattered forbs such as <i>Lappula squarrosa, Ipomopsis pumila, Allium textile, Arenaria hookeri</i>, and the cactus <i>Opuntia polyacantha</i>. There are nine other dwarf-shrubland associations and two shrublands with <i>Atriplex gardneri</i> dominant or codominant in the canopy, but none are codominated by <i>Picrothamnus desertorum</i>.  Accession Code: urn:lsid:vegbank.org:commConcept:30348-{869F7FEE-6331-4490-8AB2-D5DC42FA53FF} Plot-observations of this Community Concept: 0
