Name: Distichlis spicata - (Hordeum jubatum) Temporarily Flooded Herbaceous Alliance Reference: Midwestern Ecology Working Group... Description: This alliance occurs in the Great Plains and western United States. This description is based on those communities found in the Great Plains. Dominant vegetation is a mixture of short and mid grasses and can have moderately sparse to dense cover. Vegetation height and cover and species diversity tend to vary inversely with salinity. Distichlis spicata is the most abundant species in stands across the range of this alliance. Other species found in the Great Plains include Grindelia squarrosa (in the northern portion of this alliance's range), Hordeum jubatum, Iva annua, Bassia scoparia (= Kochia scoparia), Pascopyrum smithii (on less saline stands), Poa arida, Puccinellia nuttalliana (in the north), Salicornia rubra (on more saline stands), Schoenoplectus maritimus (= Scirpus maritimus), Sporobolus airoides, and Suaeda calceoliformis (on more saline stands). Widely scattered low shrubs, especially Atriplex patula and Sarcobatus vermiculatus, can be found on sites in the western and central Great Plains. Trees are not found on stands of this alliance. Stands of this alliance are found in depressions and along the margins of saline lakes and ponds. Most of the stands are flooded or saturated for a few weeks in the spring and after heavy rains; some have water present for most of the growing season. The soils range from sand to clay and from moderately well-drained to poorly drained. Most are deep and moderately to strongly saline. Stands that have good drainage in the surface soils usually have a deeper impermeable or slowly permeable layer that allows retention of water. Fires which spread from upland prairies may have moved through the more dense stands, but many stands did not have sufficient vegetation to support fires.  Accession Code: VB.CC.19163.DISTICHLISSPICA Plot-observations of this Community Concept: 0
