Name: Leymus cinereus - Distichlis spicata Alkaline Wet Meadow Reference: NatureServe Biotics 2019 Description: This community is located on the Columbia Plateau in Idaho, Oregon, Nevada, Washington and California, as well as the Uinta Basin of northwestern Colorado. This is a small-patch community ranging from 1-1000 acres in size that is restricted to alkaline or saline soils, often in swales or stream terraces. The water table can be shallow, or soils may have an impermeable layer holding a perched water table or may have a fine texture (e.g., clay loam) that holds water well. The community is composed of <i>Leymus cinereus</i> that forms an open 4-foot tall or taller bunchgrass layer and a 2-foot tall or less, dense rhizomatous <i>Distichlis spicata</i> grass cover. <i>Leymus cinereus</i> and <i>Distichlis spicata</i> are always present and can be the only vascular species present. <i>Carex praegracilis, Equisetum laevigatum, Pascopyrum smithii, Poa fendleriana, Poa secunda</i>, and <i>Spartina gracilis</i> may be present, although usually with less cover than the diagnostic species. Patches of exposed ground are common in more saline sites. The exotic annual grass <i>Bromus tectorum</i> is present to abundant in disturbed sites. <i>Achillea millefolium</i> is found in most sites in the Great Basin, and <i>Asclepias speciosa</i> is common in Uinta Basin stands. This is a low-diversity community with 5-17 species per plot. Total vegetative cover is rarely less than 50%.  Accession Code: urn:lsid:vegbank.org:commConcept:30390-{F3DECC73-DCEF-41CE-B65D-F99B0B1FC39D} Plot-observations of this Community Concept: 0
