Description:
Acidic seepage swamp of southern New England and adjacent areas dominated by Acer rubrum. These generally occur in seasonally saturated situations on slightly sloping hillsides, along small streams, or in basins that receive overland flooding in addition to groundwater influence. In general, these swamps are acidic and have some seepage indicators, but are not particularly species-rich. Soils are shallow to moderately deep mucks over mineral soils. Acer rubrum dominates the canopy; Fraxinus pennsylvanica or Fraxinus americana are usually also found in the canopy. Fraxinus nigra is not generally associated with this type, and if present occurs only as scattered individuals. Conifers, like Tsuga canadensis or Pinus strobus, are generally absent or occur in very low abundance. The shrub layer may be fairly open to quite dense, depending on the amount of canopy closure. Shrub species commonly include Ilex verticillata, Rhododendron viscosum, Clethra alnifolia, Lindera benzoin, and less commonly Vaccinium corymbosum, Lyonia ligustrina, Toxicodendron vernix, Viburnum dentatum, and Viburnum nudum var. cassinoides (= Viburnum cassinoides). The herbaceous layer is variable in cover, and Symplocarpus foetidus and Osmunda cinnamomea are nearly always present. Other herbaceous species include Impatiens capensis, Carex stricta, Veratrum viride, Osmunda regalis, Onoclea sensibilis, Thelypteris palustris, and Glyceria spp. Microtopography is generally pronounced, resulting from tip ups. Tree seedlings and Sphagnum mosses are common on hummocks, but do not in general form extensive carpets. Additional nonvascular species can include Plagiomnium cuspidatum (= Mnium cuspidatum) and Calliergon spp.
