Comm #7271	Leersia oryzoides - Boehmeria cylindrica - Ranunculus flabellaris Herbaceous Vegetation » more details accession code: VB.CC.31033.CEGL006903 NOT CURRENTLY ACCEPTED	Eastern Ecology Working Group of...	0	This open, graminoid-dominated herbaceous community occurs on the flat to gently sloping bottoms or moats of calcareous sinkhole ponds in the Valley and Ridge Province of northwest New Jersey. The dominant species are <i>Boehmeria cylindrica, Leersia oryzoides</i>, and <i>Ranunculus flabellaris</i>. The most common associates include <i>Bidens connata, Bidens frondosa, Carex lupulina, Carex squarrosa, Echinochloa muricata var. muricata, Eleocharis acicularis, Eleocharis palustris, Glyceria septentrionalis, Pilea pumila, Polygonum amphibium</i>, and <i>Sparganium erectum ssp. stoloniferum (= Sparganium chlorocarpum)</i>. In disturbed conditions the non-native species <i>Polygonum persicaria</i> or <i>Microstegium vimineum</i> may be present and locally abundant. Rare plants associated with this community include <i>Glyceria acutiflora, Ranunculus flabellaris</i>, and <i>Sagittaria cuneata</i>. This herbaceous community occurs primarily on Ordovician Allentown dolomite with glacial outwash (kettle) surficial deposits. Occasionally it occurs in solution sinkholes on Epler Rickenbach dolomite with glacial till/bedrock complex surficial deposits. The soils are muck, rarely silty clay or silt marl, and overlay clay, sandy clay, shell marl, peat or bedrock. This community is seasonally flooded. Slope is flat to gentle or occasionally moderate. Aspect is variable and elevation range is 150 to 185 m (492-610 feet) above mean sea level.
Comm #7272	Fagus grandifolia - Quercus (alba, velutina, prinus) / Kalmia latifolia Forest » more details accession code: VB.CC.30964.CEGL006919	Eastern Ecology Working Group of...	0	This mixed forest of beech and oaks occurs on the Inner Coastal Plain and outer Piedmont from New Jersey to southern Virginia. It is particularly common on steep ravine slopes and bluffs of dissected terrain with highly acidic soils. It occurs occasionally on short, steep bluffs of the Outer Coastal Plain, and occasionally occurs on elevated swamp islands with sandy, oligotrophic soils. The overstory is composed of <i>Fagus grandifolia</i> with variable codominance by several oaks, particularly <i>Quercus prinus, Quercus alba</i>, and <i>Quercus velutina</i>. Minor associates include <i>Quercus coccinea, Acer rubrum, Carya</i> spp., and <i>Liriodendron tulipifera</i>. Typical subcanopy trees include <i>Sassafras albidum, Acer rubrum, Nyssa sylvatica, Cornus florida, Amelanchier arborea</i>, and <i>Ilex opaca</i>, the latter frequently dominating in Coastal Plain stands. An evergreen shrub layer with strong dominance by <i>Kalmia latifolia</i> is characteristic, with low-cover associates of <i>Rhododendron periclymenoides, Vaccinium</i> spp., and <i>Gaylussacia baccata</i>. Deciduous ericads alone are dominant in rare patches that lack <i>Kalmia latifolia</i>. On northern exposures, <i>Fagus grandifolia</i> tends to strongly dominate, and <i>Kalmia latifolia</i> may achieve >75% cover.

Comm #7275	Fagus grandifolia - Betula lenta - Quercus (alba, rubra) / Carpinus caroliniana Forest » more details accession code: VB.CC.31308.CEGL006921	Eastern Ecology Working Group of...	0	This mesic hardwood forest occurs in the northern Piedmont of New Jersey, Delaware, and is likely to occur in Maryland. This association occurs on gently sloping sites, and soils may be rocky. The canopy is characterized by <i>Fagus grandifolia, Liriodendron tulipifera</i>, and <i>Betula lenta</i>, with associated species including <i>Quercus alba, Quercus rubra, Nyssa sylvatica, Fraxinus americana</i>, and <i>Carya</i> spp. The shrub layer is dominated by <i>Carpinus caroliniana</i>, with lesser amounts of <i>Cornus florida, Hamamelis virginiana</i>, and <i>Lindera benzoin</i>. Other shrub associates include <i>Viburnum acerifolium, Vaccinium pallidum, Viburnum dentatum</i>, and <i>Hamamelis virginiana</i>. The herbaceous layer is characterized by <i>Polystichum acrostichoides, Arisaema triphyllum, Thelypteris noveboracensis, Mitchella repens, Medeola virginiana, Polystichum acrostichoides, Parthenocissus quinquefolia, Polygonatum biflorum, Galium circaezans, Botrychium virginianum</i>, and <i>Amphicarpaea bracteata</i>. This association is similar to ~<i>Fagus grandifolia - Quercus (alba, rubra) - Liriodendron tulipifera / (Ilex opaca var. opaca) / Polystichum acrostichoides</i> Forest (CEGL006075)$$ but is characterized by the presence of <i>Betula lenta</i> and the lack or negligible presence of Coastal Plain species such as <i>Ilex opaca</i> or <i>Liquidambar styraciflua</i>.
Comm #7276	Quercus laurifolia - Sabal palmetto / Myrsine floridana - Psychotria nervosa Forest » more details accession code: VB.CC.35181.CEGL007060	Southeastern Ecology Working Gro...	0	This association includes slightly higher hammock islands surrounded by wet prairies of southern Florida. This wetland hammock association occurs in southern Florida, but its range is north of most other tropical hardwood hammocks. The canopy is dominated by warm temperate species <i>Quercus laurifolia</i> and <i>Sabal palmetto</i>. Tropical species, e.g., <i>Myrsine floridana</i> and <i>Psychotria nervosa</i>, are prominent in the subcanopy and shrub strata. These communities often form `tree islands,' surrounded by wet prairies.

Comm #7278	Acer rubrum - Fraxinus pennsylvanica - Liquidambar styraciflua / Carex laevivaginata - Carex stricta - Glyceria septentrionalis - (Symplocarpus foetidus) Forest » more details accession code: VB.CC.30933.CEGL006965 NOT CURRENTLY ACCEPTED	Eastern Ecology Working Group of...	0	This is an Outer Coastal Plain red maple - green ash - sweetgum swamp of New Jersey, with a canopy dominated by <i>Acer rubrum, Fraxinus pennsylvanica</i>, and <i>Liquidambar styraciflua</i>. Other potential canopy associates include <i>Quercus phellos, Betula populifolia, Fagus grandifolia, Magnolia virginiana, Nyssa sylvatica</i>, and <i>Ilex opaca</i>. Shrubs can include <i>Viburnum dentatum, Vaccinium corymbosum, Ilex verticillata, Clethra alnifolia</i>, and <i>Rhododendron viscosum</i>. The diverse herbaceous layer is dominated by a variety of sedges, including <i>Carex laevivaginata, Carex stricta, Carex intumescens, Carex debilis, Carex abscondita, Carex folliculata</i>, and <i>Carex atlantica ssp. capillacea</i>, as well as <i>Glyceria septentrionalis, Symplocarpus foetidus, Onoclea sensibilis, Osmunda cinnamomea, Osmunda regalis, Thelypteris palustris</i>, and <i>Impatiens capensis</i>. <i>Sphagnum</i> spp. are common throughout the swamp. The Coastal Plain setting and presence of <i>Liquidambar styraciflua, Ilex opaca</i>, and <i>Magnolia virginiana</i> distinguish this association from ~<i>Acer rubrum - Fraxinus (pennsylvanica, americana) / Lindera benzoin / Symplocarpus foetidus</i> Forest (CEGL006406)$$.

Comm #7280	Casasia clusiifolia - Guapira discolor - Pithecellobium keyense - Metopium toxiferum / Solanum bahamense / Hymenocallis latifolia Forest » more details accession code: VB.CC.36221.CEGL007005	Southeastern Ecology Working Gro...	0	These are diverse hammock forests of the Florida Keys, developed not on consolidated rock, but on storm-deposited shell hash of biogenic origin, consisting of limestone sand, shell, and calcareous algal fragments. They are variable in height, from 3 m or less on the coastal edge, to 8 m, but are most typically 5-7 m tall. The canopy and subcanopy are diverse, consisting most frequently of mixtures of <i>Guapira discolor, Eugenia foetida, Metopium toxiferum, Pithecellobium keyense, Casasia clusiifolia, Suriana maritima, Conocarpus erectus, Bursera simaruba, Coccoloba uvifera, Eugenia axillaris, Coccothrinax argentata, Reynosia septentrionalis, Sideroxylon celastrinum (= Bumelia celastrina), Piscidia piscipula, Erithalis fruticosa</i>, and the exotic <i>Casuarina equisetifolia</i>. Frequent shorter shrubs and herbs include various species associated with coastal dunes and other shore-associated habitats: <i>Lantana involucrata, Solanum bahamense, Hymenocallis latifolia, Lasiacis divaricata, Alternanthera maritima, Opuntia stricta, Sesuvium portulacastrum, Suaeda linearis</i>. These forests can be distinguished from Rockland Hammocks [see ~<i>Bursera simaruba - Coccoloba diversifolia - Eugenia axillaris</i> Forest Alliance (A2030)$$] by the usual presence and abundance of species such as <i>Casasia clusiifolia, Suriana maritima</i>, and <i>Guapira discolor</i>, the frequent presence of shoreline shrubs and herbs [see above], the shoreline landscape position, and the unconsolidated substrate.
