This <i>Pinus taeda</i>-dominated forest occurs in the southwestern extremity of the Upper West Gulf Coastal Plain of Texas and may occur elsewhere in the region. The most characteristic feature of this community is the strong dominance of <i>Sabal minor</i>. The overstory is dominated by <i>Pinus taeda</i>, followed closely by <i>Quercus nigra, Ostrya virginiana</i>, and <i>Liquidambar styraciflua</i>. <i>Ostrya virginiana</i> and <i>Fraxinus americana</i> are the most important midstory species. The understory is strongly dominated by <i>Sabal minor</i> with patches of sedges (<i>Carex</i> spp.) and other herbaceous species infrequently scattered throughout. Many of the plant species present are believed to indicate a rich nutrient and/or pH status in the region. |

This mixed pine forest found in the Upper Coastal Plain west of the Mississippi River is codominated by <i>Pinus echinata</i> and <i>Pinus taeda</i>. These forested communities naturally occur in limited areas of the region, typically on dry uplands but occasionally on more mesic sites. Hardwoods rarely enter the canopy of stands although occasional individuals may be present. Shrub composition and density are variable depending upon management regimes and moisture conditions. Stands with dense shrub layers tend to have sparse or patchy herbaceous layers, but some highly managed older stands (which have been thinned and frequently burned) can have a fairly abundant ground cover. <i>Chasmanthium sessiliflorum</i> is a typical ground layer dominant or codominant. This community occurs on a range of soil types, including clay loams, sandy loams underlain by clay, and even some deeper sands. |

This forest is dominated by a mixed <i>Chamaecyparis thyoides - Pinus elliottii var. elliottii</i> canopy which typically ranges between 65 and 80% cover. A subcanopy of <i>Nyssa biflora</i> and <i>Acer rubrum var. trilobum</i> is present. <i>Sabal palmetto</i> and <i>Serenoa repens</i> are abundant on hummocks. This saturated forest association is restricted to the East Gulf Coastal Plain of Mississippi, Florida, and possibly Alabama. It occurs in large, constantly saturated basins or poorly drained flats which are inundated under several feet of water during the high precipitation/low evapotranspiration period of spring. The sandy subsoil is overtopped by thick peat and muck. Fire is an infrequent event. |

This association occurs in North Carolina on tidal ridges on the edge of estuarine sounds, and is occasionally flooded by wind tides. Canopy dominants are <i>Acer rubrum</i> and <i>Acer negundo</i>, with lesser amounts of <i>Nyssa aquatica, Taxodium distichum</i>, and <i>Ulmus rubra</i>. Various woody vines, including <i>Nekemias arborea, Sicyos angulatus, Parthenocissus quinquefolia, Vitis rotundifolia, Matelea gonocarpos, Smilax rotundifolia, Clematis crispa</i>, and <i>Toxicodendron radicans</i>, are abundant and form dense tangles. <i>Sambucus nigra ssp. canadensis</i> is the most abundant shrub. Because of natural disturbance events resulting from shoreline position, this community has a battered, uneven canopy and heavy development of woody vines. |
