Name:
Acer rubrum - Fraxinus pennsylvanica / Polygonum spp. Floodplain Forest
Reference:
NatureServe Biotics 2019
Description:
This freshwater tidal woodland occurs on tidal rivers in Connecticut, Massachusetts, New York, and New Jersey. It is found on larger rivers with gradual slopes and is flooded by diurnal tides. The substrate is very wet. The canopy is characterized by <i>Acer rubrum, Fraxinus pennsylvanica</i>, with <i>Ulmus rubra</i> and <i>Carpinus caroliniana</i> being frequent associates and with <i>Chamaecyparis thyoides, Thuja occidentalis</i>, or <i>Quercus bicolor</i> occurring locally in some occurrences. The shrub layer is characterized by <i>Ilex verticillata, Alnus serrulata, Clethra alnifolia, Rhododendron viscosum, Vaccinium corymbosum, Lindera benzoin, Cornus racemosa, Cornus amomum, Cornus sericea, Cephalanthus occidentalis</i>, and others. The herbaceous layer is a very diverse mixture of freshwater tidal marsh species and palustrine species and is characterized by <i>Peltandra virginica, Pontederia cordata, Impatiens capensis, Leersia oryzoides, Onoclea sensibilis, Pilea pumila, Polygonum punctatum, Polygonum hydropiper, Polygonum hydropiperoides, Polygonum sagittatum, Zizania aquatica, Asclepias incarnata</i>, and <i>Arisaema triphyllum</i>. This freshwater tidal swamp occurs at the upper limit of tidal influence along coastal rivers. They are best developed along larger rivers with a gradual elevation gradient such that tidal influence occurs over considerable distance. There is diurnal flooding with freshwater. Substrate is continuously wet and there is distinct hummock-and-hollow microtopography.
