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 Fraxinus pennsylvanica and Ulmus americana. Widely scattered old Populus deltoides occur as remnants of a previous successional stage. The often dense shrub layer is dominated by Symphoricarpos occidentalis. Other shrubs present include Rosa woodsii, Juniperus scopulorum (which can also be in the canopy or subcanopy), and Prunus virginiana. Symphoricarpos occidentalis tends to increase under grazing pressure, and it may be almost the only shrub where grazing has been intense. Herbaceous species present include Pascopyrum smithii, Andropogon gerardii, Poa spp., Carex spp. (wide leaf), Rumex spp., Carex filifolia, Anemone cylindrica, Piptatherum micranthum (= Oryzopsis micrantha), Galium spp., Anemone canadensis, Taraxacum spp., Lappula spp., Conyza canadensis, and Cirsium spp.  Accession Code: VB.CC.25030.FRAXINUSPENNSYL Plot-observations of this Community Concept: 0
