Name: Fraxinus pennsylvanica - Ulmus americana / Symphoricarpos occidentalis Forest
Reference: Midwestern Ecology Working Group...
Description: This ash - elm woody draw community type is found in the northern Great Plains of the United States and Canada. Stands occur on upland sites along steep north-facing slopes and, occasionally, along intermittent drainages or near the bases of north-facing slopes of upland sites. Soils are typically moist and poorly drained, and usually silty clay or clay. This is a moderately to densely vegetated forest with an open to dense shrub understory. The average height of the tree layer is 5-8 m. The tree layer is dominated by <i>Fraxinus pennsylvanica</i> and <i>Ulmus americana</i>. Widely scattered old <i>Populus deltoides</i> occur as remnants of a previous successional stage. The often dense shrub layer is dominated by <i>Symphoricarpos occidentalis</i>. Other shrubs present include <i>Rosa woodsii, Juniperus scopulorum</i> (which can also be in the canopy or subcanopy), and <i>Prunus virginiana</i>. <i>Symphoricarpos occidentalis</i> tends to increase under grazing pressure, and it may be almost the only shrub where grazing has been intense. Herbaceous species present include <i>Pascopyrum smithii, Andropogon gerardii, Poa</i> spp., <i>Carex</i> spp. (wide leaf), <i>Rumex</i> spp., <i>Carex filifolia, Anemone cylindrica, Piptatherum micranthum (= Oryzopsis micrantha), Galium</i> spp., <i>Anemone canadensis, Taraxacum</i> spp., <i>Lappula</i> spp., <i>Conyza canadensis</i>, and <i>Cirsium</i> spp.
