This <i>Pinus palustris</i>-dominated community occurs on dry, sandy, well-drained soils in the East Gulf Coastal Plain of north Florida, where this type has been considered "some of the most spectacular high pineland" on the Apalachicola National Forest (Clewell 1971). The open canopy is dominated by <i>Pinus palustris</i>; a subcanopy is typically absent. <i>Quercus incana</i> and <i>Quercus margarettae</i> sprouts dominate the short-shrub stratum and can vary in density depending on fire history. The herb layer is dominated by <i>Aristida beyrichiana</i>, along with other grasses such as <i>Panicum virgatum, Schizachyrium scoparium</i>, and <i>Sporobolus junceus</i>. Related sandhill types of the region often support <i>Quercus laevis</i> in the subcanopy, often with a shrub layer component of <i>Serenoa repens</i> which is completely lacking in this type. |

This community type is broadly defined to accommodate mid- to late-successional upland forests strongly codominated by <i>Pinus taeda</i> and <i>Liquidambar styraciflua</i>, resulting from past disturbance (such as agricultural or other land clearing). Understory composition differs based on edaphic site and on age and history. This broadly defined type occupies a variety of edaphic sites, ranging from mesic through dry-mesic sites on a wide variety of (generally acidic) soils. If left unmanaged or undisturbed, this can be a short-lived forest type, which is likely to succeed with greater age into various oak- and oak-pine-dominated forests. |

This open <i>Pinus palustris</i> woodland is found in the Florida Panhandle and adjacent and southern Alabama on xeric, sandy soils with a slightly higher fine particle composition in the surface soils, and higher species richness than other Florida sandhill types (e.g., ~<i>Pinus palustris / Quercus laevis / Aristida beyrichiana - Tephrosia chrysophylla</i> Woodland (CEGL007132)$$). <i>Quercus laevis</i> is the most constant and abundant oak in the subcanopy/shrub layer, but <i>Quercus incana, Quercus geminata</i>, and <i>Quercus margarettae</i> are also common and typically abundant. <i>Schizachyrium scoparium var. stoloniferum</i> is the most constant dominant species in the herbaceous layer, but <i>Aristida beyrichiana</i> is also often dominant, despite being slightly less constant in this type. Indicator species include <i>Gaylussacia dumosa, Licania michauxii, Vaccinium darrowii</i>, among the shrubs, and <i>Aristida mohrii, Commelina erecta, Croton argyranthemus, Eriogonum tomentosum, Euphorbia floridana, Liatris gracilis, Pityopsis aspera, Rhynchosia cytisoides</i>, and <i>Schizachyrium tenerum</i>, among the herbs. Many of these indicators are restricted to the panhandle of Florida. |

This chaparral shrubland occurs in the interior Central Coast Ranges, from the Santa Monica Mountains to northern San Benito County, California. It occurs on gentle to very steep slopes of variable but often southerly aspects, along a wide range of elevations from 5 to 1585 m (16-5200 feet). This association usually occurs on alluvial/depositional, lower to upper slopes that are undulating or convex. The parent material is highly variable, including granitic, volcanic, or sedimentary substrates. Soils are various loams, sands, and clays. <i>Eriogonum fasciculatum</i> is consistently present at low to high cover. A wide variety of chaparral, coastal sage, and disturbance shrub species (e.g., <i>Adenostoma fasciculatum, Artemisia californica, Ericameria linearifolia, Ceanothus cuneatus, Corethrogyne filaginifolia, Lotus scoparius, Rhus ovata, Salvia apiana, Hesperoyucca whipplei</i>) may be present at low cover. Diverse annual herbs comprise the herbaceous understory, the most common being natives <i>Cryptantha</i> spp. and <i>Dichelostemma capitatum ssp. capitatum</i>, and non-natives such as <i>Hirschfeldia incana, Erodium brachycarpum, Erodium cicutarium, Bromus</i> spp., and <i>Avena</i> spp. Occasionally there is an emergent tree layer, with species such as <i>Juniperus californica, Pinus sabiniana</i>, and <i>Quercus douglasii</i> found at trace cover. |

This silver maple - green ash - elm forest is found throughout the midwestern United States and parts of the eastern United States. Stands occur on medium to large, regularly flooded floodplains. The canopy cover is more-or-less closed and dominated by <i>Acer saccharinum, Fraxinus pennsylvanica, Ulmus americana</i>, and <i>Populus deltoides</i>. Associated species may include <i>Ulmus rubra, Acer negundo, Salix nigra, Celtis occidentalis</i>, and <i>Carya cordiformis</i>. More southward, <i>Platanus occidentalis</i> and <i>Betula nigra</i> may occur. The shrub and sapling layer is often open (<25% cover). Species that may be present include <i>Sambucus nigra ssp. canadensis, Rubus occidentalis</i>, or <i>Lindera benzoin</i>. Woody and herbaceous vines can be prominent, including among the woody vines <i>Parthenocissus quinquefolia, Toxicodendron radicans</i>, and <i>Vitis riparia</i>. Herbaceous vine species include <i>Apios americana, Amphicarpaea bracteata</i>, and <i>Echinocystis lobata</i>. Herbaceous grasses, forbs, and ferns dominate the ground layer, including <i>Symphyotrichum lateriflorum, Boehmeria cylindrica, Erythronium americanum, Solidago gigantea, Cinna arundinacea, Leersia virginica, Elymus virginicus, Impatiens pallida, Laportea canadensis, Matteuccia struthiopteris, Onoclea sensibilis, Pilea pumila, Urtica dioica</i>, and others. A variety of exotics may be present, including <i>Lysimachia</i> spp., <i>Microstegium vimineum, Polygonum cuspidatum, Rosa multiflora</i>, and <i>Lonicera japonica</i>. |

This association includes <i>Quercus rubra</i> forests at intermediate elevations (mostly below 1067 m [3500 feet], ranging from 610-1220 m [2000-4000 feet]) occurring in the Southern Blue Ridge Escarpment, the Smoky Mountains and the Southern Blue Ridge. It may possibly range into adjacent areas of the Cumberland Plateau. These forests occur on mostly northern to eastern and southeastern, mid to upper, moderately steep slopes of intermediate exposure over acidic soils. The canopy is dominated by <i>Quercus rubra</i>, often with other oaks and <i>Acer rubrum</i> and/or <i>Liriodendron tulipifera</i> codominating. Other minor canopy species may include <i>Betula lenta, Carya tomentosa, Carya glabra, Halesia tetraptera, Quercus alba, Quercus montana</i>, and <i>Magnolia fraseri</i>. In some examples, hickories are sparse or absent. The subcanopy and sapling strata include the canopy species, as well as <i>Halesia tetraptera, Betula lenta, Tsuga canadensis, Cornus florida, Acer pensylvanicum</i>, and <i>Oxydendrum arboreum</i>. The shrub stratum is typically sparse but may have local dominance by <i>Gaylussacia ursina</i> or <i>Rhododendron maximum</i>. Herbaceous cover is sparse to moderate but can be species-rich. Ferns can be locally dominant, typically <i>Thelypteris noveboracensis</i> and <i>Athyrium filix-femina ssp. asplenioides</i>. This forest is distinguished from High Elevation Red Oak forests [see associations in ~<i>Quercus rubra - Quercus alba</i> Montane Forest Alliance (A3116)$$] by lack of species such as <i>Betula alleghaniensis, Ilex montana, Vaccinium simulatum</i>, and by lacking abundant <i>Hamamelis virginiana</i>, as well as its occurrence at generally lower elevations. It is also characterized by having a more mixed oak composition (versus nearly monospecific <i>Quercus rubra</i>). In the Southern Blue Ridge Escarpment region, these montane oak-hickory forests seem to occupy environments intermediate between more-protected forests dominated by <i>Quercus alba</i> and drier more-exposed <i>Quercus montana</i> forests. |
