Nyssa biflora Swamp Forest Alliance
Reference:
NatureServe Biotics 2019
Description:
These are forests codominated by <i>Nyssa biflora</i> and <i>Acer rubrum</i> occurring on extensive peat flats in the southeastern coastal plains, in seepage-fed edges of floodplains or on slopes wet by nearly constant seepage. <i>Liriodendron tulipifera</i> is a common woody species in these forests, as are <i>Acer rubrum, Carpinus caroliniana, Fraxinus pennsylvanica, Liquidambar styraciflua, Magnolia virginiana, Oxydendrum arboreum, Persea palustris, Quercus laurifolia, Quercus michauxii, Pinus taeda</i>, and <i>Ulmus rubra</i>. Some common dominants in the shrub layer include <i>Ilex coriacea, Leucothoe axillaris, Lyonia lucida, Morella caroliniensis</i>, and <i>Toxicodendron vernix</i>, with <i>Arundinaria gigantea, Clethra alnifolia, Ilex glabra, Itea virginica</i>, and <i>Rhododendron flammeum</i> also often present. <i>Sphagnum</i> spp. are common in the ground layer, as well as <i>Boehmeria cylindrica, Carex atlantica ssp. capillacea, Carex bromoides ssp. bromoides, Hydrocotyle verticillata var. verticillata, Ludwigia palustris, Macbridea caroliniana, Mitchella repens, Osmunda cinnamomea, Osmunda regalis var. spectabilis, Sagittaria fasciculata, Saururus cernuus</i>, and <i>Woodwardia areolata</i>. The hydrology is constantly saturated, and soils are acidic and organic. In the East Gulf Coastal Plain, these forests are found on slopes in a longleaf pine-dominated upland. Examples of forests in this alliance are known from the Atlantic Coastal Plain from Virginia to Georgia, the Upper East Gulf Coastal Plain of Alabama, the East Gulf Coastal Plain of Mississippi, and likely other adjacent states as well.
