Name: Acer rubrum - Fraxinus pennsylvanica Seasonally Flooded Forest Alliance Reference: Midwestern Ecology Working Group... Description: This alliance is widely distributed in the eastern United States. Stands are dominated by broad-leaved deciduous trees and well-developed shrub and herbaceous strata. They are characterized by dense growth and a great diversity of species. Basal area can reach 40-42 m2/ha. Acer rubrum and Fraxinus pennsylvanica are consistently abundant overstory species, but Fraxinus profunda (in the southern parts of this alliance's range), Liquidambar styraciflua, Quercus lyrata, Quercus bicolor, and Ulmus americana occur almost as frequently, and Nyssa aquatica and Taxodium distichum occur sporadically in the southern parts of this alliance's range. Acer saccharinum may dominate in parts of the range. The shrub layer can include a diverse mixture including Carpinus caroliniana, Cephalanthus occidentalis, Forestiera acuminata, and Ilex decidua, but Itea virginica is characteristic of southern stands of this alliance. Even with dense shading, the herbaceous layer is usually well-developed, displaying a preponderance of Boehmeria cylindrica, Carex spp., Glyceria spp., Juncus spp., Laportea canadensis, Leersia spp., and Pilea pumila. Vitis spp. are characteristic vines of this community, but Toxicodendron radicans and Campsis radicans are also prominent. Sites which support stands of this alliance have level or nearly level soils that formed in water-deposited clayey or loamy sediments on floodplains of the Mississippi and other rivers and large perennial streams in the Coastal Plain. These soils are flooded or saturated for a significant portion of the growing season, and water may be ponded for most of the year in shallow depressions. Flooding can reach 1 m. Flooding occurs during the winter and spring and often extends into the growing season.  Accession Code: VB.CC.18921.ACERRUBRUMFRAXI Plot-observations of this Community Concept: 0
