Description:
This dogwood - willow shrub swamp community type 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 Salix spp., which collectively share dominance with Cornus sericea. Willow species include Salix bebbiana, Salix discolor, Salix eriocephala, Salix interior, Salix fragilis, and Salix petiolaris. Other shrubs associates include Cephalanthus occidentalis (southeastward), Cornus amomum, Ribes americanum, Rosa palustris (more common eastward), Rosa blanda and Rosa woodsii var. woodsii (= Rosa macounii) (more common westward), Rubus pubescens (northward), Rubus idaeus ssp. strigosus (= Rubus strigosus), Sambucus canadensis, Spiraea alba, and Viburnum lentago. Woody vines present include Clematis virginiana, Parthenocissus quinquefolia, and Toxicodendron radicans. Characteristic herbs include 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, and Thalictrum dasycarpum. A variety of sedges may dominate more open stands, including Carex lacustris and Carex stricta. Tree species include Acer rubrum, Fraxinus pennsylvanica, and Ulmus americana.
