Short graminoid vegetation of semipermanently flooded zones of Coastal Plain pondshores. Usually standing water present, but water table may drop below surface late in growing season, although sediments generally remain saturated. Characteristic species include <i>Eriocaulon aquaticum, Lobelia dortmanna</i>, and <i>Isoetes</i> spp. Additional, intermittent species include <i>Schoenoplectus pungens (= Scirpus pungens), Utricularia gibba, Sagittaria graminea, Gratiola aurea, Juncus pelocarpus, Eleocharis acicularis</i>, and <i>Sparganium americanum</i>. |

With ~Nymphoides aurea$ as a dominant or strong component, and presence of other rooted aquatic plants with floating leaves. Free-floating and/or submersed species can also occur. Typical in lakes of the white-sand area of western Cuba, in slightly oligotrophic or eutrophic waters. |

Magnolia virginiana - Nyssa (biflora, sylvatica) - Acer rubrum / Morella caroliniensis / Woodwardia areolata Forest

This broad-leaved, evergreen forest represents one of two described phases of "baygalls" in the West Gulf Coastal Plain. Key diagnostic species of this association include the nominals, <i>Magnolia virginiana, Nyssa sylvatica, Acer rubrum, Morella caroliniensis</i>, and <i>Woodwardia areolata</i>. Endemic to Texas, Louisiana, and southern Arkansas, this "northern" type lacks indicator species of related environments in the southern portions of the region, such as <i>Cyrilla racemiflora</i> and <i>Ilex coriacea</i>. This forest occurs on saturated soils at the headwaters and margins of topographically flat creek bottoms associated with springs and seepage flow. These communities are invariably embedded within sandy slopes and uplands. |

This transitional hardwood - spruce forest occurs in montane regions of northern New England, the Northern Appalachians, and in adjacent Canada. This forest is most extensive at middle elevations, between 305 and 760 m (1000-2500 feet), occurring on slopes with rocky, nutrient-poor, and often shallow till soils that are well-drained to excessively well-drained. This association forms a relatively broad transitional zone between northern hardwood forests and montane spruce-fir forests. The canopy varies from nearly closed to partly open. Shrubs, herbs, and tree regeneration forms a dense cover in gaps; under closed canopies, understory layers can be sparse. The dominant trees are <i>Picea rubens</i> and a variable mixture of the northern hardwoods <i>Acer saccharum, Betula alleghaniensis</i>, and <i>Fagus grandifolia</i>. Other canopy associates include <i>Acer rubrum, Abies balsamea, Thuja occidentalis</i>, and <i>Betula papyrifera</i>. <i>Abies balsamea</i> may be the major conifer, in either the canopy or subcanopy, in stands that have been selectively logged. Shrub and herbaceous layers contain species common to both northern hardwood and spruce-fir forests. Characteristic shrubs include <i>Sorbus americana, Sorbus decora, Acer pensylvanicum, Acer spicatum</i>, and <i>Viburnum lantanoides (= Viburnum alnifolium)</i>. Characteristic herbs include <i>Dryopteris intermedia, Dryopteris campyloptera, Clintonia borealis, Oxalis montana, Linnaea borealis, Maianthemum canadense, Streptopus lanceolatus var. roseus (= Streptopus roseus)</i>, and <i>Aralia nudicaulis</i>. The bryophyte layer is of variable cover and may include <i>Bazzania trilobata, Dicranum scoparium, Hypnum imponens, Hylocomium splendens, Leucobryum glaucum</i>, and <i>Polytrichum commune</i>. On the ground, this community can grade into both northern hardwood forest and spruce-fir forest types; this type is distinguished by the codominance of conifers and hardwoods. |
