Reference:
NatureServe Biotics 2019
Description:
This natural early-successional community occurs in the Southern Blue Ridge of North Carolina and Tennessee and presumably in the adjacent Piedmont and possibly Ridge and Valley, and likely occurs in adjacent states. It is found on coarse-textured or mixed-textured depositional bars and islands subject to frequent flooding and scouring. Soils are usually sandy, periodically droughty when exposed, and tightly packed in a matrix of cobbles or boulders. Local microsites may have a significant silt component and be poorly drained. The physiognomy of this community is extremely variable with frequency of disturbance and time since last disturbance. Vegetation is extremely variable in structure and composition. <i>Platanus occidentalis</i> is the most frequent woody dominant, with <i>Cornus amomum</i> also frequent. Other common woody species include <i>Fraxinus pennsylvanica, Liquidambar styraciflua, Salix nigra, Ulmus alata, Nyssa sylvatica</i>, and <i>Acer rubrum</i>. Herbaceous vegetation is often extremely diverse, and is a mixture of species shared with floodplain forests, upland forests, and weedy species. Species with frequency over 70% include <i>Dichanthelium clandestinum, Oenothera biennis, Elymus</i> spp., <i>Solidago rugosa, Verbesina alternifolia, Apios americana, Boehmeria cylindrica, Impatiens capensis, Juncus tenuis, Lycopus virginicus, Polygonum cespitosum var. longisetum, Viola sororia</i>, and the exotics <i>Artemisia vulgaris</i> and <i>Rumex crispus</i>. Vines are often present; <i>Clematis virginiana</i> and <i>Parthenocissus quinquefolia</i> occur with high frequency.
