Name: Taxodium distichum / Lemna minor Forest Reference: Southeastern Ecology Working Gro... Description: This bald-cypress swamp is found in the Atlantic and Gulf coastal plains of the United States in a variety of ecological settings. Examples may occur in oxbow lakes and ponds, and along the banks of rivers and lakes in saturated or flooded soils. This type is characterized by a monospecific canopy of straight, tall individuals of <i>Taxodium distichum</i> above shallow to deep water (depths ranging from soil saturation to approximately 6 m) during all or most of the year. Flooding is seasonal, occurring during winter and spring. Stands have a sparse to moderate subcanopy and depauperate shrub and herb layers. The trunks of the canopy trees typically form swelled buttresses. Canopy cover is variable, from at or near 100% to less than 60% in some examples. More open examples of this type tend to occur in deeper water. In the deepest water situations scattered trees grow over an open water surface covered by floating and submersed aquatic plants. <i>Taxodium distichum</i> regeneration is absent in areas of permanent inundation, as seed germination does not occur in standing water. The subcanopy and herbaceous layers are dependent upon timing, duration, and depth of flooding. <i>Cephalanthus occidentalis</i> and <i>Rosa palustris</i> may be common shrubs in some examples of this community, while <i>Fraxinus caroliniana</i> (in its range) and <i>Acer rubrum var. drummondii</i> are common in the subcanopy. Shallow water emergents, floating-leaved aquatics, such as <i>Azolla caroliniana, Brasenia schreberi, Cabomba caroliniana, Hydrocotyle ranunculoides, Limnobium spongia, Spirodela punctata, Wolffia columbiana, Lemna</i> spp. <i>Nymphaea</i> spp., and submerged hydrophytes, such as <i>Ceratophyllum demersum, Egeria densa, Myriophyllum aquaticum</i>, and <i>Potamogeton nodosus</i>, are common in permanent water zones throughout the range of <i>Taxodium distichum</i> swamps. This community is differentiated from other swamp forests by lacking <i>Nyssa</i> spp. as other than occasional individuals. This is the only community type currently defined outside Florida with <i>Taxodium distichum</i> as the sole dominant.  Accession Code: VB.CC.35103.CEGL002420 Plot-observations of this Community Concept: 0
