This association includes mostly evergreen woodlands dominated by <i>Pinus pungens</i> and/or <i>Pinus rigida</i>, occurring over a dense ericaceous shrub stratum, on sharp ridges, mostly above 610 m (2000 feet) elevation in the Southern Blue Ridge. This type is also found in limited areas of the inner Piedmont and Cumberland Mountains. This woodland occurs across a wide elevational range (485-1220 m [1600-4000 feet]), on exposed ridges and upper slopes with southerly and westerly exposures, over thin, excessively drained, nutrient-poor soils, and can be associated with rock outcroppings. Canopy coverage can often approach that of a forest, especially in areas where fire has been excluded and deciduous species have significant coverage. Deciduous species that can be important, particularly in the subcanopy, include <i>Quercus montana, Quercus coccinea, Quercus stellata, Nyssa sylvatica, Acer rubrum</i>, and <i>Oxydendrum arboreum</i>. <i>Pinus virginiana, Pinus echinata</i>, and <i>Pinus strobus</i> can have high coverage and even codominate on some sites. The shrub stratum is dominated by ericaceous species, typically <i>Kalmia latifolia</i> and <i>Eubotrys recurva</i> in the tall-shrub stratum and <i>Vaccinium pallidum</i> as a low shrub. Other shrub species vary with location but include <i>Vaccinium stamineum, Vaccinium simulatum, Vaccinium pallidum, Vaccinium hirsutum, Vaccinium corymbosum, Rhododendron maximum, Rhododendron minus, Gaylussacia ursina, Gaylussacia baccata, Buckleya distichophylla, Pyrularia pubera</i>, and <i>Fothergilla major</i>. Species commonly found in the sparse herb stratum include <i>Chimaphila maculata, Galax urceolata, Pteridium aquilinum var. latiusculum, Xerophyllum asphodeloides, Chamaelirium luteum, Comptonia peregrina, Leiophyllum buxifolium, Gaultheria procumbens, Iris verna, Dichanthelium</i> spp., and <i>Epigaea repens</i>, although herbaceous species composition will vary within the range of this community. <i>Smilax glauca</i> is a common vine. Without periodic fire, this community will gradually succeed into forests dominated by <i>Acer rubrum</i> or <i>Quercus montana</i> and <i>Quercus coccinea</i>, except on the most extreme sites, where this vegetation is self-perpetuating. It is thought that woodlands dominated by <i>Pinus pungens</i> are associated with more xeric conditions than woodlands dominated by <i>Pinus pungens</i> in combination with other tree species. |

This forest of mesic to submesic, well-drained soils occurs in the Piedmont and Coastal Plain of Virginia and Maryland, extending north to southern New England on the Coastal Plain. It also occurs occasionally at low elevations of the Blue Ridge and adjacent Ridge and Valley in Virginia and Maryland. It is characteristically a mixed forest dominated by <i>Fagus grandifolia, Quercus alba, Quercus rubra</i>, and <i>Liriodendron tulipifera</i> in various proportions. Overstory associates over the range include <i>Quercus velutina, Quercus falcata, Quercus coccinea, Liquidambar styraciflua, Acer rubrum, Nyssa sylvatica, Carya tomentosa, Carya glabra</i>, and <i>Fraxinus americana</i>. The subcanopy is characterized by young <i>Fagus grandifolia, Acer rubrum, Carpinus caroliniana, Cornus florida</i>, and <i>Sassafras albidum</i>. <i>Ilex opaca</i> is particularly characteristic and abundant on the Coastal Plain. The shrub layer varies from very sparse to well-developed and can include <i>Asimina triloba, Viburnum acerifolium, Viburnum dentatum</i>, and <i>Euonymus americanus</i>. Heath shrubs, such as <i>Vaccinium corymbosum</i> and <i>Vaccinium pallidum</i>, may be common but not abundant. Vines are common, including <i>Parthenocissus quinquefolia, Smilax glauca</i>, and <i>Toxicodendron radicans</i>. In the southern part of the range, <i>Oxydendrum arboreum</i> and <i>Vitis rotundifolia</i> may be conspicuous members of the understory. The herb layer is composed of <i>Polystichum acrostichoides, Thelypteris noveboracensis, Uvularia perfoliata, Cypripedium acaule, Mitchella repens, Tipularia discolor, Goodyera pubescens, Eurybia divaricata, Chimaphila maculata, Carex swanii, Medeola virginiana, Athyrium filix-femina, Carex digitalis, Carex willdenowii, Epifagus virginiana, Maianthemum canadense, Desmodium nudiflorum, Polygonatum biflorum, Podophyllum peltatum, Arisaema triphyllum</i>, and <i>Maianthemum racemosum</i>. |
