Name: Acer rubrum / Rhododendron viscosum - Clethra alnifolia Forest Reference: Eastern Ecology Working Group of... Description: This red maple swamp occurs in poorly drained depressions containing acidic, tannic water without substantial nutrient input from overland flow. The core of distribution is the North Atlantic Coast and adjacent Lower New England / Northern Piedmont ecoregions. Soils are organic and hummock-hollow microtopography is evident. <i>Acer rubrum</i> dominates the canopy often with abundant <i>Nyssa sylvatica</i>. The subcanopy varies from sparse to fairly well-developed and may feature <i>Ulmus americana</i> or occasionally <i>Quercus bicolor</i>, along with additional <i>Acer rubrum</i>. The shrub layer is characterized by <i>Vaccinium corymbosum, Clethra alnifolia, Ilex verticillata, Rhododendron viscosum, Leucothoe racemosa</i>, and on the Atlantic Coastal Plain <i>Ilex glabra</i> may also be present. The herbaceous layer is not particularly diverse, characterized by <i>Osmunda cinnamomea, Symplocarpus foetidus, Carex intumescens, Osmunda regalis, Arisaema triphyllum</i>, and <i>Onoclea sensibilis</i>. <i>Sphagnum</i> mosses make up the bryophyte layer. This community is differentiated from <i>~Acer rubrum - Nyssa sylvatica - Betula alleghaniensis / Sphagnum</i> spp. Forest (CEGL006014)$$ by the absence or infrequent occurrence of <i>Tsuga canadensis, Betula alleghaniensis, Nemopanthus mucronatus, Carex trisperma, Clintonia borealis</i>, and by the presence of species with more southern affinities such as <i>Clethra alnifolia, Ilex glabra</i>, and <i>Rhododendron viscosum</i>.  Accession Code: VB.CC.31394.CEGL006156 Plot-observations of this Community Concept: 0
