Sumter National Forest Final Report - NatureServe

epeated flooding, this community may remain on a site indefinitely. It develops from communities dominated by Salix spp. andPopulus spp., and probably from others.Environment: This forest occurs on active first bottoms and possibly on levees where flooding may be frequent but is of shortduration. Because of repeated flooding, this community may remain on a site indefinitely. This is a Zone IV community with alikelihood of 51-100% of flooding with intermittent periodicity for 1-2 months (12.5-25% of total) of the growing season. Floodingusually occurs in late winter and spring. Common soil orders for this community include Entisols, Inceptisols and Alfisols, and soilsare relatively fertile because of frequent sediment deposition. It develops from communities dominated by Salix spp. and Populusspp., and probably from others.Vegetation: Stands of this forest are dominated by Platanus occidentalis and Liquidambar styraciflua. Other woody speciescommon to this community include Aesculus sylvatica, Cornus florida, Alnus serrulata, Fraxinus americana, Acer rubrum, Asiminatriloba, Toxicodendron radicans, Parthenocissus quinquefolia, Ulmus americana, Fagus grandifolia, and Euonymus americana.Herbaceous species that may be found include Arisaema triphyllum, Sanicula canadensis, Saururus cernuus, Campanula divaricata,Dichanthelium dichotomum var. dichotomum, Viola sororia, and Carex crinita.Dynamics: This is a Zone IV community with a likelihood of 51-100% of flooding with intermittent periodicity for 1-2 months(12.5-25% of total) of the growing season. Flooding usually occurs in late winter and spring. Because of repeated flooding, thiscommunity may remain on a site indefinitely. It develops from communities dominated by Salix spp. and Populus spp., and probablyfrom others.Similar Associations:• Platanus occidentalis - Celtis laevigata - Fraxinus pennsylvanica / Lindera benzoin - Ilex decidua / Carex retroflexa Forest(CEGL007730) -- somewhat overlapping in range, in different alliance (A.288).Related Concepts:• Eutrophic Seasonally Flooded Forest (Rawinski 1992) B• IIA6f.

Related vegetation in the Interior LowPlateau may belong in the I.B.2.N.d Platanus occidentalis - (Fraxinus pennsylvanica, Celtis laevigata, Acer saccharinum)Temporarily Flooded Forest Alliance (A.288). This association (and its alliance A.289) was originally conceived as having a moremontane or upper piedmontane affinity, in contrast to associations in A.288. This type may be more likely in the upper/innerPiedmont (in contrast to CEGL007730, of A.288, which is more likely in the portions of the Piedmont closer to the Coastal Plain, e.g.,the Oconee National Forest).CONSERVATION RANKING & RARE SPECIESGRank: G5 (1997-6-23): No informationHigh-ranked species: No informationELEMENT DISTRIBUTIONRange: The community occurs in the Piedmont of Virginia, North Carolina, South Carolina and Georgia.
