NatureServe Biotics 2019  33 This open, forb-dominated vegetation is currently described from the karst region of the Ridge and Valley Province of New Jersey. It occurs on the slopes and flats of calcareous sinkhole ponds formed in dolomite with surficial deposits of glacial till, with soils composed of silt loam, silty clay loam, or silty clay, overlaying clay or bedrock. The dominant species are <i>Boltonia montana, Symphyotrichum racemosum</i>, and <i>Mentha arvensis</i>. Associates include <i>Asclepias incarnata, Cyperus strigosus, Carex cryptolepis, Carex lurida, Carex typhina, Carex viridula, Cuphea viscosissima, Eleocharis palustris, Eragrostis frankii, Eupatorium perfoliatum, Iris versicolor, Dichanthelium acuminatum var. fasciculatum, Panicum capillare, Panicum rigidulum var. pubescens, Polygonum amphibium</i>, and <i>Sium suave</i>. The macroalga <i>Chara</i> sp. is a common associate, as are the bryophytes <i>Hypnum lindbergii, Campylium stellatum</i>, and <i>Amblystegium serpens</i>.

Fagus grandifolia - Quercus alba - (Acer floridanum) / Mixed Herbs Forest

accession code: urn:lsid:vegbank.org:commConcept:35477-{0699FF94-823C-4F25-BFF4-4B91F953E598}
NatureServe Biotics 2019  33 This association includes forests of mesic and calcareous slopes of the Atlantic Coastal Plain. The canopy is typically dominated by <i>Fagus grandifolia</i> and <i>Quercus alba</i>, with <i>Acer floridanum</i> present in some stands within its range. Characteristic species include <i>Carya tomentosa, Viburnum acerifolium, Crataegus marshallii</i>, and <i>Crataegus spathulata</i>. The herb layer is diverse with a variable composition. This is a general concept type which needs better definition; its relationship to other types in this alliance needs to be defined.

Pinus palustris / Quercus laevis / Schizachyrium scoparium - Stipulicida setacea Woodland

NatureServe Biotics 2019  33 This xeric association occurs primarily in the Fall-line Sandhills region of the South Atlantic Coastal Plain of Georgia and adjacent South Carolina, but can occur on isolated pockets of coarse sand further east along major rivers. This type occurs on xeric, coarse sands and is relatively species-poor. <i>Pinus palustris</i> forms an open canopy and <i>Quercus laevis</i> is the dominant species in the subcanopy layer, although <i>Quercus incana</i> and <i>Quercus margarettae</i> are also typical. The shrub layer is relatively sparse and is characterized most notably by <i>Gaylussacia dumosa</i> and <i>Vaccinium stamineum</i>. The two most abundant species in the herbaceous stratum are <i>Aristida beyrichiana</i> and <i>Schizachyrium scoparium</i>, although <i>Aristida beyrichiana</i> is absent in this type in the wiregrass gap of South Carolina. Other characteristic herbaceous species include classic xerophytes such as <i>Cnidoscolus urens var. stimulosus, Aureolaria pectinata, Euphorbia ipecacuanhae, Minuartia caroliniana, Stipulicida setacea</i>, and <i>Stylisma patens</i>.

Pinus palustris / Schizachyrium scoparium - Pteridium aquilinum Woodland

accession code: urn:lsid:vegbank.org:commConcept:36552-{C69A66DE-B7CD-472E-8712-E0B6E48B2824}
NatureServe Biotics 2019  33 This longleaf pine woodland occurs in a variety of xeric to subxeric situations on upland ridges, knolls, and slopes of the East Gulf Coastal Plain of Georgia and less commonly in the Fall-line Sandhills region of South Carolina. Surface soils are typically sandy loams with very high silt content, often in association with ironstone hardpans or other clayey B horizons. The relatively closed canopy is dominated by <i>Pinus palustris</i> while the subcanopy layer is typically open and is characterized by a mix of scrub oaks and mesic hardwood species. Despite high percentages of silt, the herb layer is not particularly species-rich, but legume and Asteraceae diversity is high compared to other xeric-subxeric types. The two most abundant and constant species in the herbaceous layer are <i>Pteridium aquilinum</i> and <i>Schizachyrium scoparium</i>.

Malacothamnus fasciculatus Shrubland
» more details
accession code: VB.CC.37462.CEGL003694
  32 This shrubland association occurs on gentle to steep southwest- and southeast-facing slopes at low elevations between 0 and 483 m. It is characterized by a strong dominance of <i>Malacothamnus fasciculatus</i> in the shrub layer. The herbaceous layer is generally insignificant and composed of mostly fire-following natives or widespread non-native weedy species. The emergent tree layer is generally absent but may include <i>Quercus agrifolia, Juglans californica</i>, and <i>Platanus racemosa</i>.

accession code: VB.CC.37466.CEGL003668
  32 This shrubland association occurs on gentle to very steep southeast- and southwest-facing slopes at low elevations between 5 and 457 m. It is characterized by a codominance of <i>Encelia californica, Salvia mellifera</i>, and <i>Malosma laurina</i> in the shrub layer. The herbaceous layer is diverse and dominated by non-native grasses and herbs. The emergent tree layer is generally absent.

NatureServe Biotics 2019  32 This community is a salt-pruned maritime shrubland of the Mid-Atlantic Coastal Plain, generally 0.5-3 m tall, with a single, extremely dense stratum, with <i>Quercus virginiana</i> dominant, and sometimes codominated by <i>Ilex vomitoria</i>. Other species may include <i>Smilax auriculata, Gelsemium sempervirens, Smilax bona-nox, Persea borbonia, Zanthoxylum clava-herculis, Pinus taeda, Juniperus virginiana var. silicicola</i>, and <i>Sabal palmetto</i>. At the northern range limit in Virginia, <i>Sabal palmetto, Smilax auriculata</i>, and <i>Persea borbonia</i> are absent, and <i>Ilex vomitoria</i> is less common, while <i>Morella pensylvanica</i> is characteristic. Other associates at the northern range limit include <i>Spartina patens, Cyperus grayi, Lechea maritima var. maritima</i>, and others characteristic of nearby dune grasslands.
