Name: Taxodium distichum - Nyssa aquatica - Nyssa biflora / Fraxinus caroliniana / Itea virginica Forest Reference: Southeastern Ecology Working Gro... Description: One type of small blackwater stream swamp forest of the Atlantic Coastal Plain, characteristically associated with ambiguously blackwater rivers. This type covers very wet forests that are flooded by river overbank flow for long periods and are dominated by combinations of Nyssa aquatica, Nyssa biflora, Taxodium distichum, and Taxodium ascendens. This type covers examples along Coastal Plain streams in regions of fine-textured soils and examples in somewhat isolated basins of brownwater floodplains, where Nyssa aquatica and Nyssa biflora are both important components of the canopy. This forest is common along small rivers that arise in the Atlantic Coastal Plain (blackwater rivers) from Virginia to northern Florida. Dominant species, which account for at least 75% of the canopy cover, are Taxodium distichum, Nyssa aquatica, and Nyssa biflora. Other bottomland species often found in this community include Acer rubrum, Liquidambar styraciflua, and Quercus laurifolia. The shrub layer generally is open, and Itea virginica is common. The herbaceous layer is very sparse and limited to higher areas and tree bases. The dominant species in this stratum is Phanopyrum gymnocarpon; other typical species include Boehmeria cylindrica, Saururus cernuus, Justicia ovata, Carex lupulina, Hydrocotyle verticillata, Mikania scandens, Spiranthes cernua, Asclepias perennis, Commelina virginica, Leersia lenticularis, and others. Some stands may have a distinctive understory of Arundinaria gigantea. Soils are semipermanently flooded, and probability of annual flooding is 100%. More work needs to be done to understand the geographic variation in the type.  Accession Code: VB.CC.28380.TAXODIUMDISTICH Plot-observations of this Community Concept: 0
