Name: Sarcobatus vermiculatus Intermittently Flooded Shrubland Alliance
Reference: Western Ecology Working Group of...
Description: This widespread shrubland alliance occurs on lowland sites in plains, mountain valleys and intermountain basins throughout the arid and semi-arid western United States. Sites are generally flat, poorly drained and 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. Shrublands included in this alliance are dominated or codominated by Sarcobatus vermiculatus. Other shrubby codominants include Picrothamnus desertorum (= Artemisia spinescens), Artemisia tridentata, Atriplex confertifolia, Atriplex gardneri, Chrysothamnus spp., or Grayia spinosa. In more saline environments, Nitrophila occidentalis and Suaeda moquinii may be present. If present, the sparse to moderate herbaceous layer is dominated by perennial grasses, such as Distichlis spicata and Pascopyrum smithii, or the perennial bunch grasses Elymus elymoides, Hordeum jubatum, Leymus cinereus, and Achnatherum hymenoides (= Oryzopsis hymenoides) will dominate. Perennial forbs are typically sparse and often include Grindelia squarrosa, Iva axillaris, and Sphaeralcea coccinea. Annual grasses, especially the exotic Bromus spp., may be present to abundant. Forbs are common on disturbed sites. Weedy annual forbs may include the exotics Descurainia spp., Helianthus annuus, Halogeton glomeratus, Lactuca serriola, and Lepidium perfoliatum. Diagnostic of this alliance is the Sarcobatus vermiculatus-dominated shrub layer in a shrubland that has a relatively shallow water table and may be flooded intermittently during the growing season.
