Name: Artemisia cana ssp. cana / Pascopyrum smithii Shrub Herbaceous Vegetation
Reference: Western Ecology Working Group of...
Description: This association has been described from the Great Plains of central and eastern Montana, far western North Dakota, northwestern South Dakota, and northeastern Wyoming. It occupies terraces and floodplains along streams, where alluvium contains more soil water than is available in the uplands. <i>Artemisia cana ssp. cana</i> dominates the shrub layer, which may also include small amounts of <i>Symphoricarpos occidentalis, Sarcobatus vermiculatus</i>, or <i>Chrysothamnus</i> sp. The undergrowth typically is dense and composed mainly of graminoids, with forbs contributing little cover. <i>Pascopyrum smithii</i> often dominates, and in many stands several other species may codominate, especially <i>Nassella viridula, Poa pratensis</i>, and <i>Bromus japonicus</i> (or another exotic, annual brome grass). Exotic grasses (<i>Poa pratensis, Bromus japonicus</i>) dominate the undergrowth in many stands. <i>Bouteloua gracilis</i> and <i>Carex filifolia</i>, both more typically upland species, may contribute substantial cover. Common forbs are <i>Taraxacum</i> spp. (exotic), <i>Achillea millefolium, Artemisia ludoviciana</i>, and <i>Vicia americana</i>.
