Name: Acer (rubrum, saccharinum) - Fraxinus spp. - Ulmus americana Forest Reference: Midwestern Ecology Working Group... Description: This silver and red maple forest swamp community type occurs in the east-central United States and adjacent Canada. Stands occur in moist, deep (>100 cm), hydric soils associated with wetland depressions on level plains and floodplain backswamps. Soils are saturated for a few months of the growing season, but often are dry by late summer. Canopy cover is complete and dominated by Acer rubrum, Acer saccharinum (in parts of the range), Fraxinus pennsylvanica, and Ulmus americana. Ulmus americana was probably the dominant species in the type prior to the introduction of Dutch elm disease (Ceratostomella ulmi). Quercus palustris and Nyssa sylvatica are also commonly encountered. The subcanopy consists primarily of Acer rubrum and Ulmus americana underlain by a shrub layer which may contain a mixture of Carpinus caroliniana, Ilex verticillata, Lindera benzoin, Sambucus canadensis, Toxicodendron radicans, Viburnum recognitum (= Viburnum dentatum var. lucidum), and Alnus incana (ssp. rugosa in parts of its range). The depth and duration of flooding and light penetrating the forest canopy regulate density and diversity found in the herbaceous layer. Impatiens capensis, Arisaema triphyllum, Glyceria striata, and a variety of Juncus spp. and Carex spp. are among the most common species encountered. Arundinaria gigantea can form dense thickets within this forest in the southern parts of the range.  Accession Code: VB.CC.25178.ACERRUBRUMSACCH Plot-observations of this Community Concept: 0
