Name: Spartina pectinata Western Herbaceous Vegetation Reference: Western Ecology Working Group of... Description: This association is common in wetlands and riparian areas of the Great Plains from eastern Montana south to Wyoming and Colorado, west to eastern Oregon and Washington, and occurs in small, scattered areas along rivers in the Colorado Plateau. Elevation ranges from 716-1770 m (2350-5800 feet). On large river floodplains, this type occurs as distinct patches and is distinguished from adjacent riparian types by micro-topography and degree of soil saturation. Substrates are usually poorly to moderately well-drained, finer textured soils, but vary to coarser textures. Stands generally occur as distinct patches in a matrix of other tallgrass and wetland associations, separated by differences in micro-topography and degree of soil saturation. This is a dense to moderately dense, tallgrass wet meadow that is characterized by being composed almost entirely of <i>Spartina pectinata</i>. Other herbaceous species such as <i>Andropogon gerardii, Calamagrostis canadensis, Carex nebrascensis, Carex pellita, Carex praegracilis, Equisetum hyemale, Glycyrrhiza lepidota, Panicum virgatum</i>, and <i>Pascopyrum smithii</i> may be present but contribute low cover. However, <i>Schoenoplectus pungens</i> may codominate some stands. Scattered woody species may also be present such as <i>Amorpha fruticosa, Chrysothamnus linifolius, Populus deltoides ssp. wislizeni, Salix exigua</i>, and the invasive exotic <i>Tamarix ramosissima</i>. The invasive thistle <i>Cirsium arvense</i> may be abundant in some stands. Historic sources cite large stands in mudflats along the Missouri and Platte rivers. Large stands have been observed south of Denver that are now threatened by housing and golf course developments.  Accession Code: VB.CC.31151.CEGL001476 Plot-observations of this Community Concept: 0
