A mesophytic hardwood forest that occurs on moist, well-drained sites in southeastern New York. The dominant trees include a mixture of five or more of the following: red oak (Quercus rubra), tulip tree (Liriodendron tulipifera), American beech (Fagus grandifolia), black birch (Betula lenta), red maple (Acer rubrum), scarlet oak (Quercus coccinea), black oak (Q. velutina), and white oak (Q. alba).
There is typically a subcanopy stratum of small trees and tall shrubs dominated by flowering dogwood (Cornus florida); common associates include witch-hazel (Hamamelis virginiana), sassafras (Sassafras albidum), red maple, and black cherry (Prunus serotina). Common low shrubs include maple-leaf viburnum (Viburnum acerifolium), northern blackberry (Rubus allegheniensis), and blueberries (Vaccinium angustifolium, V. pallidum). The shrublayer and groundlayer flora may be diverse.
Characteristic groundlayer herbs are white wood aster (Aster divaricatus), New York fern (Thelypteris noveboracensis), Virginia creeper (Parthenocissus quinquefolia), jack-in-the-pulpit (Arisaema triphyllum), wild geranium (Geranium maculatum), spring beauty (Claytonia virginica), Solomon's-seal (Polygonatum biflorum), and false Solomon's-seal (Maianthemum racemosum). |

This association represents herbaceous interdune wetland depressions on barrier islands, dominated by <i>Spartina patens</i> and <i>Setaria parviflora</i>, sometimes with scattered <i>Baccharis angustifolia</i>. The herb layer consists of species with maritime and calcareous affinities (some brackish influence from salt aerosol and hurricane overwash). Other characteristic species include <i>Rhynchospora colorata, Cynanchum angustifolium, Panicum virgatum, Sabatia stellaris, Morella cerifera, Sabal palmetto</i>, and <i>Dichanthelium aciculare</i>. This type occurs in Alabama and Florida and possibly as far north as South Carolina. |

A grassland community that occurs on rolling outwash plains of the glaciated portion of the Atlantic coastal plain, near the ocean and within the influence of offshore winds and salt spray. This community is dominated by grasses that usually form a turf; the grasses collectively have greater than 50% cover. Low heath shrubs may be present, with less than 50% cover.
The dominant grasses are little bluestem (Schizachyrium scoparium), common hairgrass (Deschampsia flexuosa), and poverty-grass (Danthonia spicata).
Other characteristic species include Pennsylvania sedge (Carex pensylvanica), rush (Juncus greenei), Indian grass (Sorghastrum nutans), Atlantic golden aster (Pityopsis falcata), bushy rockrose (Helianthemum dumosum), hoary frostweed (H. propinquum), flat-top goldenrod (Euthamia graminifolia), white-topped aster (Aster paternus), pussy's-toes (Antennaria plantaginifolia), bitter milkwort (Polygala polygama), hyssop-leaved boneset (Eupatorium hyssopifolium), bayberry (Myrica pensylvanica), shining sumac (Rhus copallinum), and northern dewberry (Rubus flagellaris). A characteristic lichen is Cladina rangiferina. |

A forested or shrub-dominated tidal wetland that occurs in lowlands along large river systems characterized by gentle slope gradients coupled with tidal influence over considerable distances. The swamp substrate is always wet and is subject to semidiurnal flooding by fresh tidal water (salinity less than 0.5 ppt).
The characteristic trees are green ash (Fraxinus pennsylvanica), black ash (F. nigra), red maple (Acer rubrum), slippery elm (Ulmus rubra), and American hornbeam (Carpinus caroliniana); northern white cedar (Thuja occidentalis) is a distinctive associate in at least one example in the Hudson Valley. Common shrubs and vines are alders (Alnus serrulata, A. incana ssp. rugosa), spicebush (Lindera benzoin), arrowwood (Viburnum dentatum), silky dogwood (Cornus amomum), red-osier dogwood (C. sericea), gray dogwood (C. foemina ssp. racemosa), Virginia creeper (Parthenocissus quinquefolia), and poison ivy (Toxicodendron radicans).
Characteristic groundlayer species are rice cutgrass (Leersia oryzoides), sensitive fern (Onoclea sensibilis), clearweed (Pilea pumila), spotted jewelweed (Impatiens capensis), common monkeyflower (Mimulus ringens), knotweeds (Polygonum hydropiper, P. hydropiperoides, P. sagittatum), skunk cabbage (Symplocarpus foetidus), hog peanut (Amphicarpaea bracteata), groundnut (Apios americana), wild yam (Dioscorea villosa), sedge (Carex grayi), Jack-in-the-pulpit (Arisaema triphyllum), and swamp milkweed (Asclepias incarnata). |

NY Heritage: Low salt marsh

A coastal marsh community that occurs in sheltered areas of the seacoast, in a zone extending from mean high tide down to mean sea level or to about 2 m (6 ft) below mean high tide. It is regularly flooded by semidiurnal tides. The mean tidal range of low salt marshes on Long Island is about 80 cm, and they often form in basins with a depth of 1.6 m or greater.
The vegetation of the low salt marsh is a nearly monospecific stand of cordgrass (Spartina alterniflora), a coarse grass that grows up to about 3 m (10 ft) tall. Salt marshes with large tidal ranges are often dominated by the tall form of Spartina alterniflora, while those with more restricted tidal ranges will maintain a short form Spartina alterniflora zone and grade into high salt marsh (Niedowski 2000). A few species of marine algae can form dense mats on the surface sediments between the cordgrass stems, including knotted wrack (Ascophyllum nodosum), and rockweed (Fucus vesiculosus); sea lettuce (Ulva spp.), and hollow green weeds (Enteromorpha spp.) can be abundant, especially in early summer. Other plants that are present in very low numbers include glassworts (Salicornia europaea, S. bigelovii), salt marsh sand-spurry (Spergularia marina), and sea blites (Suaeda spp.).
Characteristic animals include clapper rail (Rallus longirostris), willet (Catoptrophorus semipalmatus), marsh wren (Cistothorus palustris), seaside sparrow (Ammodramus maritimus), fiddler crabs (Uca pugilator and U. pugnax) nesting along creek banks, ribbed mussel (Geukensia dimissa), and at high tide mummichog (Fundulus heteroclitus), and several other small fishes that live in the tidal creeks at low tide.
The low salt marsh is one zone within a coastal salt marsh ecosystem; it occurs in a mosaic with several other communities. Low salt marsh grades into high salt marsh at slightly higher elevations, and into intertidal mudflats at slightly lower elevations. Tidal creeks that drain the salt marsh flow in a sinuous pattern through the marsh, with a narrow band of low marsh lining the banks of the tidal creeks. Shallow depressions, or pannes, may also occur in the low marsh. |
