Name: Fraxinus pennsylvanica - Ulmus americana / Prunus virginiana Woodland
Reference: Midwestern Ecology Working Group...
Description: This community type occurs in the northwestern Great Plains of the United States. Stands occur in upland ravines and broad valleys or on moderately steep slopes. They also occurs along small permanent or ephemeral streams, including deep mesic ravines and canyon bottoms that are not flooded or saturated. On these sites, soil and topography permit greater than normal moisture. The soils are clay loams, sandy clay loam, and sandy loam, dry to moist, and moderately well-drained. The parent material is typically colluvium or alluvium. This community is an open- to closed-canopy woodland dominated by <i>Fraxinus pennsylvanica</i>. <i>Ulmus americana</i> or <i>Acer negundo</i> sometimes achieve codominance. In undisturbed stands, the understory is composed of two layers. The taller and more conspicuous layer is a shrub layer 2-3 m tall. This layer is dominated by <i>Prunus virginiana</i> with smaller amounts of <i>Symphoricarpos occidentalis</i> or more rarely <i>Ostrya virginiana</i>. The lower layer is dominated by grasses and sedges such as <i>Elymus virginicus, Elymus villosus</i>, and <i>Carex sprengelii</i>. Common herbaceous species include <i>Aquilegia canadensis, Cerastium arvense, Thalictrum dasycarpum, Galium boreale, Galium aparine, Maianthemum stellatum</i>, and <i>Thalictrum dasycarpum</i>. The continuation of the status of <i>Ulmus americana</i> as a prominent part of this community is uncertain due to the effects of Dutch elm disease.
