Name: Fraxinus pennsylvanica - (Ulmus americana) / Symphoricarpos occidentalis Forest
Reference: Midwestern Ecology Working Group...
Description: This ash - elm forest type is found in the northeastern Great Plains of the United States and Canada. Stands are found on nearly level floodplains and lower terraces of rivers and streams, generally away from the river on older, stabilized sites. The water table may be relatively deep on higher terraces, allowing drier species to establish. Soils are typically clays or silty clays. The tree layer is variable in structure, ranging from open (25-50%) to closed (50% or more) canopy. Fraxinus pennsylvanica is the leading dominant. In some parts of the range Juniperus scopulorum is present in the subcanopy, particularly where the canopy is still open. Populus deltoides may be present as an emergent. Emergent Populus deltoides may also occur under a canopy of Fraxinus pennsylvanica, reflecting a successional shift in some stands. Fraxinus pennsylvanica is common in the subcanopy and sapling layer, and, in some stands, Ulmus americana may be an associate. Acer negundo may only be occasionally present in some parts of the range. The dominant shrub is Symphoricarpos occidentalis. Other shrub species may be present, including Cornus sericea, Rosa woodsii, and Rhus aromatica. A variety of herbs may be present, none at high cover values, including Elymus canadensis, Maianthemum stellatum, Melilotus officinalis, Muhlenbergia racemosa, Parthenocissus vitacea, Poa pratensis, Thalictrum dasycarpum, and Toxicodendron rydbergii.
