Name: Atriplex confertifolia Shrubland Alliance
Reference: Western Ecology Working Group of...
Description: This shrubland alliance occurs across the western U.S. from the eastern Mojave Desert and Great Basin east to the western Great Plains. These shrublands are usually associated with valley bottoms or alluvial slopes with medium- to fine-textured soils, but may occur on coarser soils of erosional slopes with calcareous substrates. In most cases, the soils are alkaline and may have substantial salt accumulation. The vegetation included in this alliance is characterized by a moderately dense shrub layer dominated or codominated by Atriplex confertifolia. Shrub associates may include Picrothamnus desertorum (= Artemisia spinescens), Atriplex polycarpa, Ephedra nevadensis, Chrysothamnus spp., Krascheninnikovia lanata, Lycium spp., Sarcobatus vermiculatus, and Tetradymia spp. The usually sparse herbaceous layer is dominated by graminoids such as Elymus elymoides, Pleuraphis jamesii (= Hilaria jamesii), Pleuraphis rigida (= Hilaria rigida), Leymus salinus, Achnatherum hymenoides (= Oryzopsis hymenoides), Pseudoroegneria spicata, Stipa spp., and other perennial bunch grasses. Diagnostic of this shrubland alliance is a shrub layer dominated or codominated by Atriplex confertifolia.
