Name: Artemisia cana Temporarily Flooded Shrubland Alliance Reference: Western Ecology Working Group of... Description: This alliance is found in the northwestern Great Plains and interior northwestern United States. This description is based largely on the type within this alliance that occurs in North and South Dakota. Stands of this alliance are found predominantly on floodplains or flat terraces near watercourses. The soils are derived from alluvial deposits and are often not well-developed. They are almost always loams, either sandy loams, silt loams, or clay loams. Flooding may occur periodically. Stands within this alliance are dominated by shrubs and graminoids approximately 1 m tall. Total vegetation cover is moderate. Graminoids make up the majority of the canopy, but the shrub layer is taller and thus more noticeable. Artemisia cana is the dominant, and often only, shrub in this stratum. Symphoricarpos occidentalis is present to common in some stands. There are also shorter shrubs such as Artemisia frigida, Krascheninnikovia lanata, Rosa woodsii, and Gutierrezia sarothrae. These rarely exceed 0.5 m. The most abundant midgrass in the Midwest is Pascopyrum smithii, with smaller amounts of Nassella viridula, Hesperostipa comata (= Stipa comata), Koeleria macrantha, and Poa pratensis. The shortgrass Bouteloua gracilis is usually present and may be very common. Forbs are present but do not contribute much of the vegetation cover in this alliance. Among the forbs that are typically found in this alliance are Achillea millefolium, Gaura coccinea, Sphaeralcea coccinea, Lactuca tatarica var. pulchella, and Taraxacum officinale.  Accession Code: VB.CC.21001.ARTEMISIACANATE Plot-observations of this Community Concept: 0
