CEGL006575 Fraxinus pennsylvanica - (Juglans nigra, Platanus occidentalis) Floodplain Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Green Ash - (Black Walnut, American Sycamore) Floodplain Forest
Colloquial Name: Green Ash - Mixed Hardwood Floodplain Forest
Hierarchy Level: Association
Type Concept: This is a green ash - mixed hardwood floodplain forest of the northern Piedmont in the mid-Atlantic eastern United States. It occurs behind levees and on low terraces that are flooded annually for short durations (less than one week per year). Water table is high for the majority of the growing season. Soils are generally silts or clay loams but can have coarser substrates where flood water velocity is higher. The canopy is codominated by Fraxinus pennsylvanica with Juglans nigra and/or Platanus occidentalis. Additional associates include Ulmus americana, Celtis occidentalis, Acer rubrum, Acer saccharinum, and Quercus palustris. In some areas Fraxinus americana may be present in place of Fraxinus pennsylvanica. Subcanopy and shrub layers are sparse and generally composed of canopy species regeneration plus Carpinus caroliniana, Carya cordiformis, Lindera benzoin, Cornus amomum, Viburnum prunifolium, and Viburnum dentatum. The invasive shrubs Rosa multiflora, Lonicera morrowii, Berberis thunbergii, and Lonicera japonica can be problematic. Herbaceous species, where exotics are not rampant, can include Impatiens pallida, Impatiens capensis, Laportea canadensis, Verbesina alternifolia, Thalictrum pubescens, Hydrophyllum canadense, Podophyllum peltatum, Symplocarpus foetidus, Circaea lutetiana, Boehmeria cylindrica, Onoclea sensibilis, Arisaema triphyllum, and Viola spp. Woody vines include Toxicodendron radicans and Parthenocissus quinquefolia. Exotic species tend to dominate the herb layer, including Alliaria petiolata, Glechoma hederacea, and Microstegium vimineum. Diagnostic features of this floodplain forest include the presence of Juglans nigra and rich herbs.

Environmental Description: These floodplain forests occur behind levees and on low terraces or mid terraces that are flooded annually for short durations (less than one week per year). It also occurs on islands, bars, and mid-terrace shorelines. The water table is high for the majority of the growing season. Soils are generally silts, sandy loams, or clay loams but can have coarser substrates where floodwater velocity is higher.
Geographic Range: Currently described from the northern Piedmont of Pennsylvania, Delaware, New Jersey, and possibly Maryland.
