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</i> (more common westward), <i>Rubus pubescens</i> (northward), <i>Rubus idaeus ssp. strigosus, Sambucus nigra ssp. canadensis, Spiraea alba</i>, and <i>Viburnum lentago</i>. Woody vines present include <i>Clematis virginiana, Parthenocissus quinquefolia</i>, and <i>Toxicodendron radicans</i>.
