CEGL007441 Fraxinus nigra - Acer rubrum / Rhamnus alnifolia / Carex leptalea Swamp Forest
Type Concept Sentence: This closed canopy deciduous swamp forest occurs in poorly drained depressions or seepage zones, primarily in the unglaciated portions of the Lower New England/Northern Piedmont and High Allegheny Plateau ecoregions. The canopy is dominated by Acer rubrum and Fraxinus nigra; associates include Betula alleghaniensis and Ulmus spp. Shrubs include Alnus incana, Lindera benzoin, and Rhamnus alnifolia.

Type Concept: This closed-canopy deciduous swamp forest occurs in poorly drained depressions or seepage zones in the unglaciated portions of the Lower New England/Northern Piedmont and High Allegheny Plateau ecoregions. This forest can occur as narrow zones to small inclusions to large swamps. Soils are generally mucky and without substantial peat development. It often occurs in areas of calcareous bedrock. The canopy is codominated by Acer rubrum and Fraxinus nigra with associates such as Betula alleghaniensis, Ulmus rubra, Ulmus americana, and Pinus strobus. The understory is patchy, ranging from shrub-dominated to sedge-dominated. Shrubs include Lindera benzoin, Toxicodendron vernix, Alnus incana, Salix spp., and Rhamnus alnifolia. The herb layer is diverse with Carex leptalea, Carex bromoides, Caltha palustris, Veratrum viride, Platanthera grandiflora, Geum rivale, Symplocarpus foetidus, Cypripedium reginae, Trollius laxus, Osmunda cinnamomea, Impatiens capensis, Cardamine bulbosa, Saxifraga pensylvanica, Dryopteris cristata, Carex lacustris, and Symplocarpus foetidus.
