Name: Quercus phellos - Quercus alba / Vaccinium fuscatum - (Viburnum nudum) / Carex barrattii Wet Forest Reference: NatureServe Biotics 2019 Description: This association encompasses forests of poorly drained shallow upland depressions on very flat landscapes of loess soils overlying Fort Payne Formation cherty limestone in the Eastern Highland Rim of Tennessee. These shallow depressions, often found at streamheads, are seasonally wet (mostly during winter and early spring) with a shallow, perched water table but tend to be dry in late summer and early fall. The canopy is dominated by <i>Quercus phellos</i> and <i>Quercus nigra</i>, and <i>Quercus alba</i> in varying amounts depending on position. Also present are <i>Liquidambar styraciflua, Acer rubrum var. trilobum</i>, and <i>Nyssa sylvatica</i>. The subcanopy is composed of the canopy species, with <i>Acer rubrum var. trilobum</i> being the most prominent. The shrub stratum is characteristically dense (ranging from 20-90% cover in a 20x20-m plot), with <i>Vaccinium fuscatum, Viburnum nudum var. nudum, Aronia arbutifolia, Rhododendron canescens</i>, and <i>Hypericum hypericoides</i>. Herbaceous density and diversity are largely regulated by the duration and depth of seasonal flooding and summer drought. The herb layer typically contains <i>Carex</i> spp. (<i>Carex joorii, Carex debilis, Carex intumescens, Carex caroliniana, Carex complanata</i>), including the disjunct <i>Carex barrattii</i> in some examples. Also found are <i>Osmunda cinnamomea, Osmunda regalis var. spectabilis, Thelypteris noveboracensis, Chimaphila maculata</i>, and <i>Mitchella repens</i>. <i>Polytrichum commune</i> and <i>Sphagnum</i> spp. are common.  Accession Code: urn:lsid:vegbank.org:commConcept:35611-{0DCB57FF-B208-4D50-8E20-4687CA2BB63B} Plot-observations of this Community Concept: 0
