Atriplex confertifolia Scrub Alliance
Reference:
NatureServe Biotics 2019
Description:
This shrubland alliance occurs across the western U.S. from the eastern Mojave Desert and Great Basin east to the western Great Plains and north to Montana. The vegetation included in this alliance is characterized by a sparse to moderately dense shrub layer dominated or codominated by <i>Atriplex confertifolia</i> and/or <i>Picrothamnus desertorum</i>. Shrub associates may include <i>Atriplex polycarpa, Ephedra nevadensis, Chrysothamnus</i> spp., <i>Krascheninnikovia lanata, Lycium</i> spp., <i>Sarcobatus vermiculatus</i>, and <i>Tetradymia</i> spp. The usually sparse herbaceous layer is dominated by graminoids such as <i>Elymus elymoides, Pleuraphis jamesii, Pleuraphis rigida, Leymus salinus, Achnatherum hymenoides, Pseudoroegneria spicata, Hesperostipa</i> spp., and other perennial bunchgrasses. These shrublands are usually associated with margins of large playas, 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.
