Native occurrences of this alliance seem to be restricted to marine terraces and headlands. Eight vegetation combinations closely linked to substrate have been described. ~Pinus radiata$ is the dominant in all of these types, and a secondary species in several other types. Stands of this alliance are dominated by ~Pinus radiata$. ~Quercus agrifolia$ may be important, and other tree species which may be present include ~Pinus muricata, Pseudotsuga menziesii, Pinus ponderosa$, and ~Sequoia sempervirens$. Variations within the shrub and herbaceous layers seem to be linked to substrate, and at least 8 distinct vegetation types have been identified. Common shrubs include ~Arctostaphylos tomentosa, Vaccinium ovatum, Toxicodendron diversilobum, Diplacus aurantiacus ssp. aurantiacus$, and ~Symphoricarpos mollis$. |

This is a common successional deciduous woodland/forest of the northern Appalachian Mountains, from New England, New York and adjacent Canada across to the northern Great Lakes. Small patches of this type are found on the Coastal Plain but are dominated by one or more of the following: <i>Populus tremuloides, Populus grandidentata</i> or the non-native <i>Populus alba</i>, and <i>Betula populifolia</i>. It occurs in various settings, often over thin glacial till. Elevation and aspect vary. The community is broadly defined and includes vegetation developing after severe disturbance such as logging, fires, severe hurricanes, or simply heavily fragmented residential development. This community can occur as closed-canopy forest or open woodland; in a few very exposed areas, it has been seen to grade to shrubland. Understory shrub cover varies from sparse to well-developed depending primarily on canopy closure. Herbs are typically sparse but may be locally dense. Bryoids are typically minor. The tree canopy is a heterogeneous mixture of light-requiring, wind-dispersed trees usually composed of several codominant species, including <i>Populus tremuloides, Populus grandidentata, Betula papyrifera, Betula populifolia, Populus balsamifera, Acer rubrum, Prunus serotina</i>, and/or <i>Prunus pensylvanica</i>. More minor components can include <i>Pinus strobus, Picea rubens, Abies balsamea, Acer saccharum, Quercus rubra, Fraxinus americana, Fraxinus pennsylvanica</i>, or <i>Ulmus americana</i> in the northern portions of the range. Scattered individuals of <i>Juniperus virginiana</i> may occur in southern examples of this community. The shrub layer can include <i>Viburnum dentatum, Lonicera morrowii, Frangula alnus (= Rhamnus frangula), Rhus typhina, Rhus copallinum, Morella pensylvanica, Rubus</i> spp., and/or <i>Viburnum dentatum</i>, in the southern portion of the range, or <i>Sorbus americana, Acer pensylvanicum, Viburnum nudum var. cassinoides</i>, or <i>Hamamelis virginiana</i>. <i>Vaccinium angustifolium, Kalmia angustifolia, Gaylussacia baccata</i>, and <i>Comptonia peregrina</i> may form a dwarf-shrub layer in the northern portion of the range. Associated herbs to the north typically include <i>Pteridium aquilinum, Deschampsia flexuosa, Festuca trachyphylla (= Festuca ovina), Cornus canadensis, Doellingeria umbellata (= Aster umbellatus), Eurybia macrophylla (= Aster macrophyllus), Danthonia spicata, Carex lucorum</i> and related species, and <i>Maianthemum canadense</i>. Typical bryoids include <i>Polytrichum commune, Polytrichum juniperinum, Dicranum</i> spp., and <i>Cladonia</i> spp. Herbs in southern examples of this community are typically old-field grasses and <i>Solidago</i> spp. In the absence of major disturbance, these forests mostly succeed to northern hardwood, spruce-fir, mixed northern hardwood-spruce-fir, or red oak - northern hardwood forests in the northern portion of the range. |

These seasonally flooded wetlands are dominated by <i>Spartina bakeri</i>, or at least with substantial cover of it. Circular ponds in which <i>Spartina bakeri</i> is typically the dominant species are found on marsh islands of the South Atlantic Coastal Plain of South Carolina and Georgia. Herbaceous dominants also include <i>Woodwardia virginica, Hibiscus moscheutos, Juncus effusus</i>, and <i>Saccharum giganteum</i>. Additional herbaceous species may include <i>Panicum virgatum, Cyperus odoratus</i>, and <i>Juncus roemerianus</i>. Scattered trees and shrubs also occur, including <i>Liquidambar styraciflua, Acer rubrum, Pinus taeda, Pinus serotina, Morella cerifera (= Myrica cerifera), Salix nigra, Diospyros virginiana, Cephalanthus occidentalis, Persea palustris</i>, and the exotic <i>Triadica sebifera (= Sapium sebiferum)</i>. Disturbance of these ponds may result in a reduction to less than 50% cover of <i>Spartina bakeri</i>. Fire is probably an infrequent event. |
