GLOBAL DESCRIPTION<br />
Concept Summary: This seasonally flooded hardwood forest community occurs in<br />
groundwater basins on the Coastal Plain of Maryl<strong>and</strong> <strong>and</strong> Virginia. The canopy is of variable<br />
closure <strong>and</strong> is dominated by Liquidambar styraciflua (sweetgum), Acer rubrum (red maple), <strong>and</strong><br />
Nyssa biflora (swamp tupelo). Associated canopy species include Quercus lyrata (overcup oak),<br />
Quercus laurifolia (laurel oak) <strong>and</strong> Diospyros virginiana (common persimmon). The shrub layer<br />
is comprised of Leucothoe racemosa (swamp doghobble) <strong>and</strong> scattered Cephalanthus<br />
occidentalis (common buttonbush). The herbaceous layer is characterized by Carex joorii<br />
(cypress swamp sedge), Carex striata var. brevis (Walter's sedge), Panicum verrucosum (warty<br />
panicgrass), Fimbristylis autumnalis (slender fimbry), <strong>and</strong> others.<br />
