This tidally flooded freshwater marsh is found in the Outer Coastal Plain of North Carolina and possibly South Carolina. Stands of this association typically consist of large, scattered <i>Taxodium distichum</i> over a graminoid-dominated, tidally flooded, freshwater marsh. Some additional canopy species could include <i>Nyssa biflora, Acer rubrum, Fraxinus</i> sp., and <i>Persea palustris</i>. The ground layer tends to be dominated by graminoids. Some examples may contain a more-or-less monospecific cover of <i>Typha angustifolia</i>. Other herbaceous dominants may occur. More information on the composition, dynamics, and status of this community is needed. |

NY Heritage: Northern white cedar swamp
» more details
accession code: VB.CC.28589.NYHERITAGENORTH

A conifer or mixed swamp that occurs on organic soils in cool, poorly drained depressions in central and northern New York, and along lakes and streams in the northern half of the state. These swamps are often spring fed or enriched by seepage of cold, minerotrophic groundwater, resulting in a stable water table and continually saturated soils. Soils are often rich in calcium. At some sites these soils have developed above a marl substrate.
The characteristic tree is northern white cedar (Thuja occidentalis), which makes up more than 30% of the canopy cover. Thuja may form nearly pure stands, or it may be mixed with other conifers and hardwoods, including red maple (Acer rubrum), eastern hemlock (Tsuga canadensis), balsam fir (Abies balsamea), tamarack (Larix laricina), yellow birch (Betula alleghaniensis), black ash (Fraxinus nigra), white pine (Pinus strobus), and black spruce (Picea mariana).
The shrub layer is usually sparse; characteristic species are dwarf raspberry (Rubus pubescens), red osier dogwood (Cornus sericea), swamp fly honeysuckle (Lonicera oblongifolia), and highbush blueberry (Vaccinium corymbosum). The groundlayer is typically diverse, with many bryophytes and boreal herbs. There are typically many hummocks formed by decaying downed trees or tip-up mounds.
Characteristic herbs on the hummocks are the sedges Carex leptalea and C. eburnea, oak fern (Gymnocarpium dryopteris), gold thread (Coptis trifolia), starflower (Trientalis borealis), bunchberry (Cornus canadensis), miterwort (Mitella nuda), Canada mayflower (Maianthemum canadense), blue bead lily (Clintonia borealis), snowberry (Gaultheria hispidula), and partridge berry (Mitchella repens).
Characteristic herbs of hollows between the hummocks are the sedge Carex intumescens, sensitive fern (Onoclea sensibilis), marsh fern (Thelypteris palustris), cinnamon fern (Osmunda cinnamomea), royal fern (O. regalis), crested wood fern (Dryopteris cristata), showy lady's-slipper (Cypripedium reginae), yellow lady's-slipper (Cypripedium calceolus), and golden ragwort (Senecio aureus).
Characteristic bryophytes are several species of Sphagnum moss, feathermosses such as Hylocomium splendens and Ptilium crista-castrensis, and leafy liverworts such as Bazzania trilobata and Trichocolea tomentella.
Characteristic birds include northern waterthrush (Seiurus noveboracensis), winter wren (Troglodytes troglodytes), white-throated sparrow (Zonotrichia albicollis), and golden-crowned kinglet (Regulus satrapa). |

NY Heritage: Maritime holly forest

accession code: VB.CC.28549.NYHERITAGEMARIT

A broadleaf evergreen maritime strand forest that occurs in low areas on the back portions of maritime dunes. The dunes protect these areas from overwash and salt spray enough to allow forest formation. In New York State this forest is best developed and probably restricted to the barrier islands off the south shore of Long Island. The trees are usually stunted and flat-topped because the canopies are pruned by salt spray and exposed to winds; the canopy of a mature stand may be only 16 to 23 ft (5 to 7 m) tall.
The dominant tree is holly (Ilex opaca). Other characteristic trees at lower abundance include sassafras (Sassafras albidum), serviceberry (Amelanchier canadensis), post oak (Quercus stellata) and black oak (Quercus velutina). Vines such as Virginia creeper (Parthenocissus quinquefolia), poison ivy (Toxicodendron radicans), greenbrier (Smilax rotundifolia), sawbrier (S. glauca), and grape (Vitis spp.) are common in the understory, and they often grow up into the canopy. Shrubs such as highbush blueberry (Vaccinium corymbosum), bayberry (Myrica pensylvanica) and black huckleberry (Gaylussacia baccata) are common in the understory, especially at the margins of the forest.
Characteristic groundlayer herbs include wild sarsaparilla (Aralia nudicaulis), starry Solomon's seal (Maianthemum stellata), and Canada mayflower (Maianthemum canadense). There may be small, damp depressions that are somewhat boggy; species found in these depressions include black gum (Nyssa sylvatica), shadbush, highbush blueberry, and chokeberry (Aronia melanocarpa). More data on characteristic animals are needed. |
