Name: Atriplex confertifolia Great Basin Shrubland Reference: Western Ecology Working Group of... Description: This shrub association occurs in scattered stands on ridges, flats, alluvial fans, talus slopes and badlands throughout the Colorado Plateau and Great Basin, often in a matrix of other high desert shrublands. Sites tend to occur on level to gentle slopes between 1158 and 2194 m (3800-7200 feet) elevation. Soils tend to be alkaline, shallow, well-drained clay loams, sometimes with a high rock or gravel content. Parent materials are variable but generally include a high percentage of calcareous source rocks. Total vegetation cover rarely exceeds 20% and is clearly dominated by <i>Atriplex confertifolia</i>. Many other species of shrubs may also be present, although they contribute little to the total canopy, including <i>Gutierrezia sarothrae, Krascheninnikovia lanata, Kochia americana, Picrothamnus desertorum, Acamptopappus shockleyi, Atriplex canescens, Ephedra nevadensis, Sarcobatus vermiculatus</i>, and <i>Ericameria nauseosa</i>. The herbaceous layer rarely has more than 5% total cover; species vary greatly by location, but common graminoids include <i>Elymus multisetus, Elymus elymoides, Leymus salinus, Poa secunda, Dasyochloa pulchella (= Erioneuron pulchellum)</i>, and <i>Pleuraphis jamesii</i>. Forbs are diverse but only contribute measurable cover in unusually wet years; <i>Chaenactis douglasii, Phacelia crenulata</i>, and <i>Mentzelia albicaulis</i> are widespread. Disturbed sites have high cover of <i>Bromus tectorum</i>.  Accession Code: VB.CC.34408.CEGL001294 Plot-observations of this Community Concept: 0
