Name: NY Heritage: Red maple-sweetgum swamp Reference: Ecological Communities of New York, 2nd Ed. Description: A hardwood swamp that occurs on somewhat poorly drained seasonally wet flats, usually on somewhat acidic gleyed to mottled clay loam or sandy loam. Red maple-sweetgum swamps often occur as a mosaic with upland forest communities. Sweetgum (Liquidambar styraciflua) is often the dominant tree or may be codominant with red maple (Acer rubrum). Other codominant trees include pin oak (Quercus palustris) and black gum (Nyssa sylvatica). Other trees occurring at lower densities include swamp white oak (Quercus bicolor), red oak (Quercus rubra) and black ash (Fraxinus nigra). Willow oak (Quercus phellos) and sweet-bay (Magnolia virginiana) are often present in larger occurrences where they may occur at very low density. Trees often have buttressed trunks and exposed roots from hydrological influences. The shrub layer is usually fairly well-developed. Characteristic shrubs are sweet pepperbush (Clethra alnifolia), swamp azalea (Rhododendron viscosum), arrowwood (Viburnum dentatum var. lucidum), spicebush (Lindera benzoin), highbush blueberry (Vaccinium corymbosum), black chokeberry (Aronia melanocarpa) and possibly fetterbush (Leucothoe racemosa). Vines such as greenbrier (Smilax rotundifolia), sawbrier (S. glauca), grape (Vitis spp.), Virginia creeper (Parthenocissus quinquefolia) and poison ivy (Toxicodendron radicans), are present at low amounts in the understory. The herbaceous layer is often dominated by ferns, including netted chain fern (Woodwardia aereolata), cinnamon fern (Osmunda cinnamomea), and sensitive fern (Onoclea sensibilis). Characteristic herbs include lizard's-tail (Saururus cernuus), Canada mayflower (Maianthemum canadense), jumpseed (Polygonum virginianum), skunk cabbage (Symplocarpus foetidus) and jewelweed (Impatiens capensis). State-reported southern red oak (Quercus falcata) and state-extirpated mistletoe (Phoradendron flavescens) occur in this community south of New York and may have been historically present in this community in New York. Some occurrences of this community are now severely degraded. More data on characteristic fauna are needed.  Accession Code: VB.CC.28747.NYHERITAGEREDMA Plot-observations of this Community Concept: 1
