This sand prairie community is found in the northern and central Great Plains of the United States and Canada. Stands are found on sandy deposits, usually on gentle to moderate slopes, ranging from stabilized rolling to choppy sand dunes. The soil is sand, loamy sand, or sandy loam, often erodible, and somewhat poorly developed. This community is dominated by moderately widely spaced mid to tall grasses. The most abundant species are <i>Andropogon hallii</i> and <i>Calamovilfa longifolia</i>. Other graminoids that may be found in this community include <i>Bouteloua gracilis, Bouteloua hirsuta, Carex duriuscula, Carex filifolia, Carex inops ssp. heliophila, Cyperus schweinitzii, Eragrostis trichodes, Hesperostipa comata (= Stipa comata), Koeleria macrantha, Muhlenbergia pungens, Redfieldia flexuosa</i>, and <i>Schizachyrium scoparium</i>. Forbs and shrubs are a minor component of the total vegetation. Characteristic forbs include <i>Chenopodium subglabrum, Chamaesyce serpyllifolia, Helianthus pauciflorus, Helianthus petiolaris, Lappula occidentalis var. occidentalis, Liatris punctata, Lithospermum incisum, Lygodesmia juncea, Monarda punctata, Oenothera rhombipetala, Penstemon haydenii</i> (in Nebraska), and <i>Psoralidium lanceolatum</i>. <i>Artemisia frigida</i> and <i>Yucca glauca</i> are the most common shrubs, especially on wind-blown dune crests and choppy slopes in Nebraska sandhills. In southeastern North Dakota, a subtype containing tallgrass species may be distinct; species include <i>Andropogon gerardii, Symphyotrichum ericoides (= Aster ericoides), Lithospermum canescens, Solidago nemoralis</i>, and <i>Sporobolus heterolepis</i>. |

Phalaris arundinacea Western Herbaceous Vegetation

This herbaceous association is reported from throughout Washington, Colorado, Nebraska, Montana, Idaho, and into northeastern Utah, but is likely more widespread in the western United States. It also occurs in Canada , in the southern two-thirds of British Columbia in areas with warm and relatively dry summers and in Alberta, from the Great Plains north into the Boreal Plains. Its distribution as a natural type is complicated because this native species is widely cultivated as a forage crop and has escaped and established in wetlands and riparian areas, displacing the local flora. Elevations range from near sea level to 2307 m. Stands are found along riparian areas, pond and lake margins, wet meadows, and intermittent drainages. The poorly drained alluvial soils are commonly fine-textured (occasionally coarse-textured) and may be flooded for brief to extended periods. The vegetation is characterized by a dense, tall herbaceous layer (often >80% canopy cover and 1.5-2 m tall) that is dominated by <i>Phalaris arundinacea</i>, which tends to occur in monocultures. Associated species may include <i>Equisetum arvense, Muhlenbergia asperifolia, Mentha arvensis, Schoenoplectus acutus (= Scirpus acutus)</i>, and many other species in trace amounts where disturbed. Introduced species such as <i>Agrostis gigantea, Bromus inermis, Bromus tectorum, Cirsium arvense, Elymus repens, Euphorbia esula, Hordeum brachyantherum, Lepidium latifolium, Melilotus officinalis, Phleum pratense, Poa pratensis</i>, and <i>Sonchus oleraceus</i> are common in some disturbed stands. |

This cordgrass wet prairie type is found in the northwestern Great Plains of the United States. Stands occur in drainage bottoms where the soil is wet for at least part of the growing season, or in poorly drained depressions within floodplains of major rivers. At Wind Cave National Park in South Dakota, this type has dense herbaceous cover, greater than 75%. Species dominance is patchy within stands, with various graminoids locally abundant, often to the exclusion of other species. In the single sampled stand, <i>Spartina pectinata, Carex nebrascensis</i>, and <i>Eleocharis palustris</i> were locally dominant. <i>Epilobium ciliatum</i> was common in shallow water. At Theodore Roosevelt National Park in North Dakota, <i>Spartina pectinata</i> is the dominant species. Species richness is generally low. <i>Hordeum jubatum</i> and <i>Pascopyrum smithii</i> are the most prominent secondary species. Elsewhere <i>Carex pellita</i> may be dominant. |
