This association consists of upland shrub thickets dominated by variable mixtures of <i>Ilex vomitoria, Quercus virginiana, Quercus geminata, Morella cerifera (= Myrica cerifera), Serenoa repens</i>, and <i>Baccharis halimifolia</i>. It occurs on rises in <i>Juncus roemerianus</i> marshes, and in other upland but extreme situations on barrier islands and barrier spits. It is likely maintained by edaphic conditions, as well as by periodic catastrophic disturbance of storm flooding and salt kill. Occasional low stature <i>Pinus elliottii</i> may be present. |

This community occurs in the mountains of Georgia, North Carolina, Virginia, and Tennessee, on ridges and steep, rocky slopes at intermediate elevations (1220-1524 m [4000-5000 feet]). It also occurs in very small patches at elevations higher than 1035 m (3400 feet) in the Cumberland Mountains along the Virginia-Kentucky border. It is a mostly evergreen shrubland, although deciduous shrubs may be present and even locally dominant. Shrubs form a dense, sometimes impenetrable thicket, 1-4 m tall. The most typical shrub dominants are <i>Kalmia latifolia</i> and <i>Rhododendron catawbiense</i>, although <i>Gaylussacia baccata, Leiophyllum buxifolium, Pieris floribunda, Rhododendron carolinianum, Rhododendron maximum</i>, and <i>Vaccinium corymbosum</i> are dominant or have high coverage in some occurrences. Other shrubs include <i>Photinia melanocarpa (= Aronia melanocarpa), Clethra acuminata, Ilex montana, Vaccinium stamineum, Leucothoe recurva</i>, and <i>Viburnum nudum var. cassinoides</i>. Small openings in the shrub canopy are dominated by lichens, bare rock or herbs, with some occurrences having up to 60% exposed rock. Herb cover beneath the shrub canopy is absent or very sparse (<5%) and may include <i>Galax urceolata, Gaultheria procumbens, Goodyera pubescens, Melampyrum lineare, Mitchella repens</i>, and <i>Pteridium aquilinum</i>. <i>Smilax rotundifolia</i> is a common vine. Small, scattered trees are possible (<i>Acer rubrum, Amelanchier laevis, Betula alleghaniensis, Ilex montana, Magnolia fraseri, Nyssa sylvatica, Oxydendrum arboreum, Picea rubens, Prunus pensylvanica, Quercus rubra</i>, and <i>Sorbus americana</i>) and may be more typical of shrublands resulting from intense fires on less exposed sites. Windfall, landslides, and small, localized, lightning-caused fires are important in the establishment and maintenance of these shrublands. This community can result from secondary succession after fire or logging or can occur as a topo-edaphic climax on steep or exposed sites. |

Rhododendron carolinianum Shrubland

This mainly evergreen shrubland occurs on steep ridges and rock outcroppings, typically at 1040-1280 m (3400-4200 feet) elevation, in the mountains of western North Carolina. It is known from areas of quartzite and meta-arkose geology in Linville Gorge Wilderness. This community has at least 25% shrub cover and may occur as a dense shrubland, 2-4 m tall, or as a shorter, more open shrubland with areas of exposed rock with fruticose and crustose lichens, scattered mats of prostrate vegetation, and isolated clumps of herbaceous species. At least 50% of the total shrub cover is made up of <i>Rhododendron carolinianum</i>. Associated shrub species vary among occurrences, but can include <i>Kalmia latifolia, Lyonia ligustrina var. ligustrina, Vaccinium corymbosum, Vaccinium pallidum, Fothergilla major, Acer rubrum, Ilex montana</i>, and low-growing <i>Gaylussacia baccata</i> and <i>Leiophyllum buxifolium</i>. Some occurrences may have occasional stunted trees of <i>Pinus pungens</i> or <i>Pinus rigida</i>. More open occurrences have significant cover by mats of <i>Selaginella tortipila</i> and scattered herbaceous species such as <i>Galax urceolata, Hypericum densiflorum, Carex umbellata, Danthonia sericea, Coreopsis major, Liatris pilosa (= Liatris graminifolia), Xerophyllum asphodeloides</i>, and <i>Schizachyrium scoparium</i>. High solar irradiation and desiccating winds, in combination with the shallow, nutrient-poor soils, are key environmental factors influencing this community. This community often occurs adjacent to or grades into xeric forests and woodlands dominated by <i>Pinus pungens, Tsuga caroliniana</i>, or <i>Quercus prinus</i>. |

This is a 'coastal scrub' community of the Panhandle of Florida, from Escambia County west to Franklin County, and in Baldwin County, Alabama, especially on the mainland (non-barrier island) coast from Destin (Walton County) east to Panama City (Bay County). It differs from Florida Atlantic Coast oak scrubs by having such panhandle species as <i>Chrysoma pauciflosculosa, Polygonella macrophylla, Lupinus westianus, Chrysopsis gossypina ssp. cruiseana, Chrysopsis godfreyi</i>, and <i>Conradina canescens</i>. Characteristic lichens are <i>Cladina evansii, Cladonia prostrata</i>, and <i>Cladonia leporina</i>. Other characteristic species include <i>Pinus clausa</i> (dwarfed), <i>Serenoa repens, Ilex vomitoria, Osmanthus americanus, Polygonella gracilis, Polygonella polygama, Balduina angustifolia, Agalinis filifolia, Asclepias humistrata</i>, and <i>Licania michauxii</i>. This community differs from more inland panhandle scrubs in the absence of a closed <i>Pinus clausa</i> canopy and infrequency of <i>Lyonia ferruginea</i> in the shrub layer. |
