Name:
Sarcobatus vermiculatus Intermountain Wet Shrubland Alliance
Reference:
NatureServe Biotics 2019
Description:
Shrublands included in this alliance are dominated or codominated by <i>Sarcobatus vermiculatus</i>. Other shrubby codominants include <i>Artemisia cana, Artemisia tridentata, Atriplex confertifolia, Atriplex gardneri, Chrysothamnus</i> spp., <i>Collomia linearis, Grayia spinosa</i>, or <i>Picrothamnus desertorum</i>. In more saline environments, <i>Nitrophila occidentalis</i> and <i>Suaeda moquinii</i> may be present. If present, the sparse to moderate herbaceous layer is dominated by perennial grasses, such as <i>Achnatherum hymenoides, Bouteloua gracilis, Distichlis spicata, Elymus elymoides, Hordeum jubatum, Leymus cinereus, Nassella viridula, Pascopyrum smithii, Poa secunda</i>, and <i>Sporobolus airoides</i>. Forbs are generally sparse except on disturbed weedy sites. The native perennial forbs include <i>Achillea millefolium, Artemisia ludoviciana, Astragalus</i> spp., <i>Chenopodium fremontii, Glycyrrhiza lepidota</i>, and <i>Opuntia polyacantha</i>. Perennial forbs are typically sparse and often include <i>Grindelia squarrosa, Iva axillaris</i>, and <i>Sphaeralcea coccinea</i>. Annual grasses, especially the exotic <i>Bromus</i> spp., may be present to abundant. Forbs are common on disturbed sites. Weedy annual forbs may include the exotics <i>Descurainia</i> spp., <i>Helianthus annuus, Halogeton glomeratus, Lactuca serriola</i>, and <i>Lepidium perfoliatum</i>. This alliance occurs throughout the arid and semi-arid western United States. Sites are generally flat, poorly drained, seasonally, temporarily or intermittently flooded with a shallow or perched water table often within 1 m depth such as alkali flats around playas and floodplains along stream channels. Substrates are generally shallow, calcareous, fine-textured soils derived from alluvium. Soils are alkaline and typically moderately saline.
