Name: Acer (rubrum, saccharinum) - Fraxinus spp. - Ulmus americana Swamp Forest
Reference: NatureServe Biotics 2019
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 (&gt;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 <i>Acer rubrum, Acer saccharinum</i> (in parts of the range), <i>Fraxinus pennsylvanica</i>, and <i>Ulmus americana</i>. <i>Ulmus americana</i> was probably the dominant species in the type prior to the introduction of Dutch elm disease (<i>Ceratostomella ulmi</i>). <i>Quercus palustris</i> and <i>Nyssa sylvatica</i> are also commonly encountered. The subcanopy consists primarily of <i>Acer rubrum</i> and <i>Ulmus americana</i> underlain by a shrub layer which may contain a mixture of <i>Carpinus caroliniana, Ilex verticillata, Lindera benzoin, Sambucus nigra ssp. canadensis, Toxicodendron radicans, Viburnum recognitum</i>, and <i>Alnus incana (ssp. rugosa</i> 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. <i>Impatiens capensis, Arisaema triphyllum, Glyceria striata</i>, and a variety of <i>Juncus</i> spp. and <i>Carex</i> spp. are among the most common species encountered. <i>Arundinaria gigantea</i> can form dense thickets within this forest in the southern parts of the range.
