Comm #451	Quercus (phellos, michauxii) / Ilex opaca / Clethra alnifolia / Woodwardia areolata Wet Forest » more details accession code: urn:lsid:vegbank.org:commConcept:33427-{C90C4C21-C429-47D6-93C0-575625DDF38A}	NatureServe Biotics 2019	42	This association occurs in the central and northern Virginia Coastal Plain and Maryland Coastal Plain on extensive, flat terraces and very wide, ancient floodplains that are no longer subject to alluvial processes. Its hydrology is seasonally to nearly permanently saturated, with occasional ponding or groundwater sheetflows, and is maintained by a high water table rather than riverine or estuarine flooding. The overstory of relatively undisturbed examples contain variable mixtures of hydrophytic oaks, most commonly <i>Quercus phellos, Quercus pagoda</i>, and <i>Quercus michauxii</i>. Associated canopy species varying from site to site can include <i>Quercus alba, Quercus palustris, Quercus lyrata, Liquidambar styraciflua, Acer rubrum, Pinus taeda, Nyssa sylvatica</i>, and <i>Fraxinus pennsylvanica</i>. The subcanopy layers are usually dominated by <i>Ilex opaca var. opaca</i> and also contain <i>Magnolia virginiana</i> and recruitment of the overstory trees. The shrub layer varies from open to dense. It most characteristically contains <i>Clethra alnifolia, Eubotrys racemosa, Ilex verticillata, Vaccinium corymbosum, Vaccinium fuscatum, Vaccinium formosum, Viburnum dentatum, Rhododendron viscosum</i>, and <i>Viburnum nudum var. nudum</i>. The herb layer is also highly variable. Some stands have a rather sparse herbaceous flora, with scattered colonies and individuals of <i>Woodwardia areolata, Osmunda cinnamomea, Osmunda regalis var. spectabilis, Woodwardia virginica, Saururus cernuus</i>, and various sedges. Others have a relatively dense graminoid-dominated herb layer with variable patch-dominance by <i>Chasmanthium laxum, Carex debilis var. debilis, Carex intumescens, Carex seorsa, Carex lonchocarpa</i>, and more rarely, <i>Carex bullata</i> or <i>Carex striata var. brevis</i>. Many stands of this association have been degraded by cutting or ditching, and extensive areas of suitable habitat have been lost to agriculture, hydrologic alterations, and conversion of hardwood forests to silvicultural pine plantations.

Comm #454	Adenostoma fasciculatum - Arctostaphylos glandulosa Shrubland » more details accession code: VB.CC.37488.CEGL003502		42	This shrubland association occurs on moderately steep to steep northeast- and northwest-facing slopes at low to mid elevations between 207 and 781 m. It is dominated by <i>Adenostoma fasciculatum</i> and <i>Arctostaphylos glandulosa</i> in the shrub layer and in the herbaceous layer. The emergent tree layer includes <i>Quercus agrifolia</i>.

Elevations range from near sea level to 3050 m (0-10,000 feet). Stands occur in small depressions in intermittent streambeds or depression ponds that flood early in the season and may dry out by summer. Soils are generally fine-textured. Stands are composed of submersed and emergent rooted vegetation under 1 m tall that is dominated by <i>Eleocharis palustris</i>, often in nearly pure stands. Vegetative cover can be sparse to dense (10-90%), but <i>Eleocharis palustris</i> is the dominant species, and the only species with 100% constancy. Other species, when present, can contribute as much as 40% cover, but never exceed that of the <i>Eleocharis palustris</i> cover.
Comm #459	Pinus palustris / Quercus pumila - Gaylussacia dumosa / Schizachyrium scoparium Woodland » more details accession code: urn:lsid:vegbank.org:commConcept:32930-{4A79D30B-70DD-4D34-B853-1EF8B570E07D}	NatureServe Biotics 2019	41	This is the drier portion of the longleaf pine woodlands of the South Carolina "wiregrass gap" with <i>Quercus pumila</i>. Stands typically have an open canopy of <i>Pinus palustris</i> with a low-shrub stratum composed of low-stature oaks such as <i>Quercus pumila</i>. Ericaceous shrubs are present, including <i>Gaylussacia dumosa, Vaccinium tenellum, Vaccinium arboreum, Vaccinium crassifolium</i>, and <i>Lyonia mariana</i>. Graminoids and forbs are diverse and abundant, with <i>Schizachyrium scoparium</i> being prominent in the stand.
Comm #460	Vernonia noveboracensis - Thelypteris palustris - Symplocarpus foetidus Seepage Meadow » more details accession code: urn:lsid:vegbank.org:commConcept:35091-{998941DB-D9C0-47E2-95BD-DF49252EA2AA}	NatureServe Biotics 2019	41	These small wetlands (&lt;1-6 acres) occur as patches within the forest matrix where calcareous groundwater discharge is present throughout the growing season. The substrate may vary from mineral soils to sapric peat (muck). Peat deposits, when present, are generally thin (&lt;50 cm). This association is characterized by a highly variable species composition. <i>Juniperus virginiana</i> may be present, and tall shrubs may be present at low cover (&lt;10%) and include <i>Salix</i> spp., <i>Lindera benzoin</i>, and <i>Toxicodendron vernix</i>. The short-shrub layer is also sparse and often dominated by willows. <i>Dasiphora fruticosa ssp. floribunda</i> is not a typical associate, and if present, is at low cover. The shrub layers may contain invasive shrubs, especially <i>Rosa multiflora, Lonicera morrowii</i>, and <i>Berberis thunbergii</i>. Open sites with little or no woody plant cover often are dominated by graminoids, while more shaded sites have a higher cover of forb species. Herbaceous vegetation typically exceeds 90% and may reach 2 m in height in some forb species. Typical forb species include <i>Vernonia noveboracensis, Thelypteris palustris, Viola</i> spp., <i>Packera aurea, Symplocarpus foetidus, Arisaema triphyllum, Hydrocotyle americana, Eupatorium</i> spp., <i>Impatiens</i> spp., <i>Pycnanthemum verticillatum, Amphicarpaea bracteata, Mitella diphylla, Solidago uliginosa, Drosera rotundifolia, Parnassia glauca</i>, and <i>Chelone glabra</i>. Typical graminoid species include <i>Carex leptalea, Carex granularis, Carex atlantica, Carex debilis, Leersia oryzoides, Muhlenbergia glomerata, Rhynchospora alba</i>, and <i>Poa palustris</i>. The invasive plants <i>Lythrum salicaria</i> and <i>Microstegium vimineum</i> may be present, the former particularly in more open seeps. Mosses are usually present but are typically &lt;5% of total vegetation cover.
