Name: Salix nigra Seasonally Flooded Forest Reference: Eastern Ecology Working Group of... Description: This association comprises a late-successional stage of interdunal swale wetland vegetation occurring on larger barrier island systems along the Atlantic Coast of Virginia and possibly North Carolina. Interdunal swale wetlands form when the freshwater aquifer intersects the dune surface and substrate is saturated for durations of time that are long enough to support peat development and accumulation. Substrate is peat over sand. This later successional phase results when the length of soil saturation is shorter, favoring the invasion of woody species. This phase is dominated by <i>Salix nigra</i>, growing in association with <i>Acer rubrum</i> in a short-statured canopy. The shrub layer is characterized by <i>Morella cerifera (= Myrica cerifera)</i>, and can be well-developed or sparse depending on the degree of peat development and variability in microtopography. The herb layer is characterized by <i>Hydrocotyle umbellata, Polygonum punctatum</i>, and <i>Bidens laevis</i>. Other herbaceous associates include <i>Thelypteris palustris var. pubescens, Boehmeria cylindrica, Triadenum virginicum, Peltandra virginica, Leersia oryzoides</i>, and others. Changes in the duration of soil saturation can invoke successional shifts in vegetation; decreased duration of soil saturation tends to maintain woody vegetation, whereas increased duration reverses succession and favors emergent herbaceous vegetation.  Accession Code: VB.CC.31086.CEGL006348 Plot-observations of this Community Concept: 0
