Midwestern Ecology Working Group...
Description:
This dogwood - willow shrub swamp community is found in the upper midwestern region of the United States and Canada. Stands are found along streams and lakes, or in upland depressions. Hydrology is variable but is typically seasonally flooded. Soils are wet, organic, and minerotrophic, with either highly decomposed peat or fine mineral soils. The vegetation is dominated by tall shrubs between 1 and 3 m tall, with at least 25% cover, and often very dense (>60% cover). More open stands may have high graminoid cover. Trees may be scattered but cover less than 25%. Composition of the shrub layer is quite diverse, primarily due to the diversity of <i>Salix</i> spp., which collectively share dominance with <i>Cornus sericea</i>. Willow species include <i>Salix bebbiana, Salix discolor, Salix eriocephala, Salix interior, Salix fragilis</i>, and <i>Salix petiolaris</i>. Other shrub associates include <i>Cephalanthus occidentalis</i> (southeastward), <i>Cornus amomum, Ribes americanum, Rosa palustris</i> (more common eastward), <i>Rosa blanda</i> and <i>Rosa woodsii var. woodsii (= Rosa macounii)</i> (more common westward), <i>Rubus pubescens</i> (northward), <i>Rubus idaeus ssp. strigosus (= Rubus strigosus), Sambucus canadensis, Spiraea alba</i>, and <i>Viburnum lentago</i>. Woody vines present include <i>Clematis virginiana, Parthenocissus quinquefolia</i>, and <i>Toxicodendron radicans</i>. Characteristic herbs include <i>Asclepias incarnata, Symphyotrichum lanceolatum var. lanceolatum (= Aster simplex), Calamagrostis canadensis, Eupatorium maculatum, Glyceria striata (= Glyceria nervata), Impatiens capensis (= Impatiens biflora), Lycopus americanus, Lycopus uniflorus, Phalaris arundinacea, Solidago gigantea</i>, and <i>Thalictrum dasycarpum</i>. A variety of sedges may dominate more open stands, including <i>Carex lacustris</i> and <i>Carex stricta</i>. Tree species include <i>Acer rubrum, Fraxinus pennsylvanica</i>, and <i>Ulmus americana</i>.
