Type Concept Sentence: No Data Available


Common (Translated Scientific) Name: (Red Maple, Silver Maple) - Green Ash / Common Winterberry / Royal Fern Floodplain Forest

Colloquial Name: Northeastern Maple - Ash Swamp Forest

Hierarchy Level:  Association

Type Concept: This maple - green ash swamp forest occurs in northern New Jersey and ranges north to the Champlain Valley of Vermont. In New Jersey, it occupies the lowest portion of calcareous sinkhole ponds and is characterized by deep organic deposits overlying marl or carbonate bedrock. This vegetation may also occur more widely in the northeast in areas underlain by calcareous bedrock. In the Champlain Valley, it occurs in peat-filled low-lying depressions formed by former bays of Lake Champlain, or in active alluvial floodplains where soils are mineral rather than organic. The tree canopy is fully closed to partially open and characterized by Acer saccharinum, Acer rubrum, Acer x freemanii (a hybrid of Acer saccharinum and Acer rubrum), and Fraxinus pennsylvanica. Other canopy associates may include Fraxinus nigra, Quercus bicolor, Ulmus americana, and occasionally in Vermont, Populus deltoides, Quercus macrocarpa, and Betula alleghaniensis. The shrub layer is characterized by Ilex verticillata, Vaccinium corymbosum, and Cornus sericea; in Vermont shrubs may also include Ribes americanum, Toxicodendron vernix, and Sambucus canadensis. The herbaceous layer is characterized by Onoclea sensibilis, Carex crinita, Boehmeria cylindrica, Carex retrorsa, Carex lupulina, Lycopus americanus, Lycopus uniflorus, Thelypteris palustris, Solanum dulcamara, and others.
