These pocosins occur in small depressions in sandy upland landscapes, differing in floristic composition, use by animal species, and community dynamics (such as fire) from more expansive pocosins occurring in other landscapes. The open canopy is dominated by <i>Pinus serotina</i>. The shrub layer is characteristically dominated by <i>Cyrilla racemiflora, Lyonia lucida</i>, and <i>Vaccinium fuscatum</i>. |

This alliance consists of seasonally flooded Coastal Plain ponds dominated by ~Cyrilla racemiflora$. Flooding is seasonal, with aquatic herbs (such as ~Utricularia purpurea$) present during periods of surface water, and non-aquatic species becoming dominant in periods of exposed soil (especially late in the growing season). |

This community represents deep-soil vegetation of calcium-rich areas in the Bluegrass Basin of Kentucky, the Nashville Basin of Tennessee, and possibly other states in the Interior Low Plateau. Due to the early and extensive use of these areas for agriculture, intact later-seral examples are extremely rare, if not extirpated. The canopy of higher quality examples is dominated by <i>Juglans nigra, Aesculus glabra var. glabra, Gymnocladus dioicus</i>, and <i>Quercus macrocarpa</i>. Less frequent canopy components would include <i>Celtis occidentalis, Prunus serotina, Carya cordiformis, Carya laciniosa, Acer nigrum, Acer saccharum, Quercus shumardii</i>, and <i>Juglans cinerea</i>. Understory species include <i>Morus rubra, Ulmus rubra</i>, and canopy species. <i>Arundinaria gigantea ssp. gigantea</i> was locally extensive, and canebrakes adjoined this community. This community had variable structure, presumably maintained by fire (perhaps once a decade). Second-growth examples are found on deep soils of woodlots and fencerows. The canopies of Bluegrass Basin examples are dominated by <i>Juglans nigra</i> and <i>Celtis</i> spp. with <i>Fraxinus americana, Prunus serotina var. serotina, Robinia pseudoacacia</i>, and scattered <i>Ulmus americana</i>. In the Nashville Basin of Tennessee, the canopy is dominated by <i>Celtis</i> spp. (<i>Celtis laevigata, Celtis occidentalis</i>) with substantial <i>Juglans nigra</i> in some examples. <i>Aesculus glabra</i> may also be present. The understory may include <i>Prunus serotina var. serotina</i> and <i>Quercus imbricaria</i>. More information is needed on higher quality examples. These forests would have naturally graded into more mesic forest vegetation containing more <i>Acer saccharum</i>, such as the ~<i>Acer (nigrum, saccharum) - Carya cordiformis</i> Forest (CEGL004411)$$ of Kentucky. |

This shrubland occurs in southern Arizona, typically on gentle to moderate slopes of ridges, foothills and mountain canyons. Sites may occur on any aspect but are typically found on warmer southern and western aspects. Plot data from Buenos Aires National Wildlife Refuge indicate elevations of 1150-1250 m (3700-4100 feet) on well-drained sandy loam. Substrates are rocky with 50% surface rock. The vegetation is characterized by an open (30% cover) tall-shrub canopy dominated by <i>Fouquieria splendens</i> (10% or more cover). If present, <i>Prosopis velutina</i> has low cover (<10%) and does not codominate the tall-shrub layer. A low-shrub layer of <i>Calliandra eriophylla</i> (<20% cover), <i>Tiquilia mexicana (= Coldenia mexicana), Ferocactus wislizeni</i>, and <i>Mimosa aculeaticarpa var. biuncifera (= Mimosa biuncifera)</i> may be present. The herbaceous layer is sparse (about 10% cover) and dominated by mixed perennial graminoids. Characteristic species are <i>Aristida ternipes, Bothriochloa barbinodis, Bouteloua chondrosioides, Bouteloua curtipendula</i>, and <i>Setaria vulpiseta (= Setaria macrostachya)</i>. Other common species include <i>Evolvulus</i> spp., <i>Gutierrezia microcephala, Krameria erecta</i>, and <i>Talinum aurantiacum</i>. <i>Eragrostis lehmanniana</i> may be present but at less 25% cover and less than a third of the total perennial graminoid layer. |

This dry to dry-mesic <i>Pinus palustris</i> woodland of the inner Atlantic Coastal Plain occurs on yellow sand soils with some silt fraction in southern South Carolina and Georgia. Stands are dominated by <i>Pinus palustris</i> with an understory containing <i>Quercus laevis</i>. Other trees present include <i>Quercus falcata, Quercus incana, Quercus laevis, Quercus margarettiae</i>, and <i>Quercus marilandica var. marilandica</i>. One characteristic low shrub is <i>Gaylussacia dumosa (= var. dumosa)</i>. Some characteristic herbaceous plants include <i>Aristida beyrichiana</i> and <i>Helianthus atrorubens</i>. |
