This community includes subxeric ridgetop and exposed slope forests in the Southern Appalachians, ranging south and east into the upper Piedmont, north into the Central Appalachians, and north and west into the Ridge and Valley. This community occurs over shallow soils, primarily on south- to west-facing slopes and ridgetops where solar exposure is high. Soils are rocky, infertile, dry, acidic sandy loams typically derived from sandstone. The community includes forests with canopies strongly dominated by <i>Quercus montana</i> and/or <i>Quercus coccinea</i>, with lesser amounts of <i>Quercus velutina, Quercus rubra, Quercus falcata, Oxydendrum arboreum, Nyssa sylvatica, Pinus virginiana</i>, and <i>Acer rubrum</i>, occurring over a typically dense shrub stratum dominated by ericaceous species. The shrub layer may vary between evergreen and deciduous dominance. Typical shrub species include <i>Kalmia latifolia, Rhododendron maximum, Vaccinium stamineum, Vaccinium pallidum, Gaylussacia ursina, Gaylussacia baccata</i>, and (in the more southern portions of the range) <i>Eubotrys recurva</i>. In addition, <i>Castanea dentata</i> may occur abundantly as root sprouts. The herb layer is typically sparse and includes subshrubs such as <i>Epigaea repens</i> and <i>Gaultheria procumbens</i>. Other common species include <i>Chamaelirium luteum, Chimaphila maculata, Galax urceolata, Magnolia fraseri, Sassafras albidum, Symplocos tinctoria, Smilax rotundifolia</i>, and <i>Smilax glauca</i>. This community is distinguished by its overall floristic composition, with a high abundance of acid-loving ericaceous species, which are indicative of this community's extremely infertile, acidic soils. |

This association includes hemlock-hardwood forests and acidic cove forests of lower to intermediate elevations in the Southern Blue Ridge, upper Piedmont, Cumberlands, and adjacent areas, ranging from southwestern Virginia and southern West Virginia, south and west to northwestern Georgia. The concept for this association is intended to be broad and cover both mixed stands of evergreen and deciduous hardwoods as well as stands dominated exclusively by deciduous trees in mesic, acidic environments. These communities occur at low to middle elevations (200-1060 m [650-3500 feet]), generally in coves, gorges or sheltered slopes, over acidic soils. The canopy is usually dominated by <i>Liriodendron tulipifera</i> or <i>Betula lenta</i> mixed with <i>Tsuga canadensis</i>, but substantial portions may be comprised mainly of <i>Tsuga canadensis</i> and the occasional <i>Acer rubrum</i>, while other sites may have little or no <i>Tsuga</i> in the canopy. Other deciduous species more typical of "rich" coves may occur as scattered individuals, including <i>Tilia americana var. heterophylla, Acer saccharum, Fraxinus americana</i>, and <i>Fagus grandifolia</i>. Other canopy/subcanopy species often include <i>Quercus alba, Quercus rubra, Magnolia fraseri</i>, and <i>Pinus strobus</i>. <i>Rhododendron maximum</i> is usually dominant in the shrub stratum, often forming impenetrable thickets. South of Virginia, woody associates may also include <i>Ilex opaca var. opaca, Calycanthus floridus, Halesia tetraptera var. tetraptera</i>, and <i>Leucothoe fontanesiana</i>. Herbaceous cover is sparse but can be diverse and is composed of acid-loving species. Typical herbs include <i>Polystichum acrostichoides, Dryopteris intermedia, Dennstaedtia punctilobula, Goodyera pubescens, Mitchella repens, Thelypteris noveboracensis, Galax urceolata, Viola rotundifolia</i>, and <i>Tiarella cordifolia</i>. |
