Name: Sarcobatus vermiculatus Intermittently Flooded Sparsely Vegetated Alliance Reference: Western Ecology Working Group of... Description: This shrubland alliance occurs along drainages in the Powder River Basin of northeastern Wyoming, at elevations ranging from 1300-1400 m. Sites are nearly flat to gently sloping stream terraces approximately 2 m above the channel. These lowland sites may receive overland flow during intense summer thunderstorms, but are well-drained and do not have shallow water tables like many intermittently flooded stands. Soils are alkaline and may be moderately saline. The alliance is characterized by a sparse to moderately dense woody layer dominated or codominated by Sarcobatus vermiculatus. Other shrubby codominants include Artemisia cana, Artemisia tridentata, and Collomia linearis. The sparse to moderately dense herbaceous layer is dominated by medium-tall bunch grasses such as Sporobolus airoides and Pascopyrum smithii with Bouteloua gracilis, Poa secunda (= Poa juncifolia), and Nassella viridula. Forbs are generally sparse except on disturbed weedy sites. The native perennial forbs include Astragalus spp., Glycyrrhiza lepidota, Achillea millefolium, Artemisia ludoviciana, Chenopodium fremontii, and Opuntia polyacantha. Annual grasses, especially the exotics Bromus tectorum and Bromus japonicus, may be present to abundant.  Accession Code: VB.CC.21333.SARCOBATUSVERMI Plot-observations of this Community Concept: 0
