Name: Atriplex gardneri - Picrothamnus desertorum Dwarf-shrubland Reference: Western Ecology Working Group of... 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 Atriplex gardneri and Picrothamnus desertorum (= Artemisia spinescens). Krascheninnikovia lanata is common in some stands, and Artemisia tridentata is often present. Herbaceous cover is very sparse (<10% cover) and may include the grasses Poa secunda, Elymus elymoides, Achnatherum hymenoides (= Oryzopsis hymenoides), Bouteloua gracilis, Sporobolus cryptandrus, scattered forbs such as Lappula squarrosa (= Lappula echinata), Ipomopsis pumila, Allium textile, Arenaria hookeri, and the cactus Opuntia polyacantha. There are nine other dwarf-shrublands associations and two shrublands with Atriplex gardneri dominant or codominant in the canopy, but none are codominated by Picrothamnus desertorum  Accession Code: VB.CC.21028.ATRIPLEXGARDNER Plot-observations of this Community Concept: 0
