Acer saccharinum / Onoclea sensibilis - Boehmeria cylindrica Forest

These silver maple floodplain forests of the northeastern United States are typical of riverbottoms, lakeplains, and the inner floodplain of medium to large rivers, mostly at less than 245 m (800 feet) elevation. They are most typical of third- and fourth-order rivers. They are subjected to spring flooding of high frequency and duration; their soils are poorly drained and deep. They are generally associated with calcareous or sedimentary bedrock and with fine-grained surficial deposits but may occur in coarser soils or tills. The canopy ranges from closed to somewhat open (in small inclusions, it may be quite sparse) and is high and arching. Shrubs are few; the herb layer is very well-developed. Bryoids are minor. The overall effect is of tall, well-spaced trees over a lush carpet of herbs. The canopy is strongly dominated by <i>Acer saccharinum</i>. Associated trees include <i>Fraxinus pennsylvanica, Ulmus americana</i>, and occasionally <i>Quercus bicolor</i> or <i>Quercus macrocarpa</i>. <i>Prunus serotina, Picea glauca</i>, and <i>Acer rubrum</i> have been occasionally noted northward. The herb layer is seasonally variable, with spring ephemerals succeeded by dense cover of mixed ferns, forbs and graminoids. Summer-dominant herbs include <i>Onoclea sensibilis</i> and <i>Boehmeria cylindrica</i>. This type differs from <i>~Acer saccharinum - (Populus deltoides) / Matteuccia struthiopteris - Laportea canadensis</i> Forest (CEGL006147)$$ in its somewhat more poorly drained soils, longer flood duration, and the reduced importance of <i>Matteuccia struthiopteris</i> relative to <i>Onoclea sensibilis</i> along with generally higher herb layer richness. It generally lacks <i>Populus deltoides</i> and <i>Salix nigra</i> in the canopy. It may be bordered on its upland edge by terrace forests dominated by <i>Acer saccharum</i>. |

Hibiscus moscheutos - Polygonum punctatum - Peltandra virginica Tidal Herbaceous Vegetation

This association is a diverse oligohaline marsh characterized by variable dominance of species found in the Chesapeake and Delaware bays. Species that form locally dominant patches can include <i>Polygonum arifolium, Hibiscus moscheutos ssp. moscheutos, Polygonum punctatum, Peltandra virginica, Leersia oryzoides, Polygonum sagittatum, Mikania scandens, Spartina cynosuroides</i>, and <i>Toxicodendron radicans</i>, among others. All of these species are able to tolerate a broad range of halinity, and the high mean species richness of this type suggests that it is generally restricted to only slightly oligohaline habitats. <i>Typha angustifolia</i> and <i>Spartina cynosuroides</i> often form large dominance patches. Infrequently present are several species that are more specific to oligohaline conditions, including <i>Echinochloa walteri, Kosteletzkya virginica, Pluchea odorata, Rumex verticillatus, Sagittaria lancifolia</i>, and <i>Teucrium canadense</i>. The colonial sedge <i>Carex stricta </i>sometimes forms local dominance patches, characteristically on hummocks raised 20-25 cm above the primary marsh surface. |

This association comprises pitch pine bogs of the Northeast. It is characterized by an open canopy of <i>Pinus rigida</i> with an understory of ericaceous shrubs such as <i>Chamaedaphne calyculata</i>. <i>Sphagnum</i> mosses form a dense mat. Canopy associates include <i>Acer rubrum, Betula populifolia</i>, and <i>Nyssa sylvatica</i>. Other shrubs include <i>Vaccinium corymbosum, Kalmia angustifolia, Photinia pyrifolia (= Aronia melanocarpa), Vaccinium myrtilloides</i>, and <i>Gaylussacia baccata</i>. <i>Eriophorum</i> spp., <i>Scirpus</i> spp., <i>Calopogon tuberosus, Vaccinium macrocarpon, Rhynchospora alba, Drosera rotundifolia, Drosera intermedia</i>, and <i>Carex trisperma</i> are typical herbs. Other herbs are <i>Cornus canadensis, Gaultheria procumbens, Pteridium aquilinum, Osmunda cinnamomea, Maianthemum canadense</i>, and <i>Trientalis borealis</i>. This type occurs on acidic soils in poorly drained depressions or basins that may have deep accumulation of peat. Often found, but not exclusively, in proximity to upland sandplain pine barrens. |

This aquatic vegetation of sheltered bays of the northeastern United States occurs on lakes and streams where it is not highly disturbed by wave action. The vegetation is dominated by submergent or emergent plants with only minor floating-leaved components. Characteristic species may include <i>Vallisneria americana, Potamogeton perfoliatus, Potamogeton epihydrus, Potamogeton nodosus, Heteranthera dubia, Heteranthera reniformis, Myriophyllum</i> spp., <i>Elodea canadensis, Utricularia</i> spp., and <i>Eriocaulon aquaticum</i>. |
