Name: Artemisia arbuscula ssp. longicaulis Shrubland Alliance Reference: Western Ecology Working Group of... Description: This shrubland alliance is known from cold, dry areas of the Intermountain West, in and around the Lahontan Basin of northwestern Nevada, southeastern Oregon, and northeastern California. Stands occur on alluvial fans, upland slopes and ridges. Soils are generally shallow and rocky. The vegetation included in this alliance is dominated by a low-shrub layer that averages more than 5% cover of Artemisia arbuscula ssp. longicaulis. Little is know about this alliance, but shrub associates could presumably include Artemisia tridentata ssp. wyomingensis, Artemisia arbuscula ssp. arbuscula, Atriplex confertifolia, Chrysothamnus spp., Ephedra spp., Ericameria spp., Grayia spinosa, Lycium shockleyi, Picrothamnus desertorum, Sarcobatus vermiculatus (= var. baileyi), and Tetradymia spp. The herbaceous layer is typically sparse, and perennial bunch grasses may include Achnatherum hymenoides, Achnatherum speciosum (= Stipa speciosa), Achnatherum thurberianum (= Stipa thurberiana), Elymus elymoides, and Poa secunda. Forb cover is likely sparse. Diagnostic of this alliance is the Artemisia arbuscula ssp. longicaulis-dominated shrub layer that has over 5% cover of the nominal species that contributes at least 40% of the total shrub cover.  Accession Code: VB.CC.20677.ARTEMISIAARBUSC Plot-observations of this Community Concept: 0
