Name: Leymus cinereus - Distichlis spicata Herbaceous Vegetation
Reference: Western Ecology Working Group of...
Description: This community is located on the Columbia Plateau in Idaho, Oregon, Nevada, Washington and California. This is a small-patch community ranging from 1-1000 acres in size that is restricted to alkaline or saline soils. The water table can be shallow. The community is composed of Leymus cinereus, that forms an open 4-foot tall or taller bunchgrass layer and a 2-foot tall or less, dense rhizomatous Distichlis spicata grass cover. Leymus cinereus and Distichlis spicata are always present with an average cover of 30% and 50%, respectively, and can be the only vascular species present. Carex praegracilis, Poa secunda (= Poa juncifolia), and Spartina gracilis are present at some sites. Patches of exposed ground are common in more saline sites. The exotic annual grass Bromus tectorum is present to abundant in disturbed sites. Achillea millefolium is found in most plots. This is a low diversity community with 5-17 species per plot.
