Ecological Communities of New York, 2nd Ed. |

A community that occurs on warm, dry, rocky ridgetops and summits where the bedrock is non-calcareous (such as quartzite, sandstone, or schist), and the soils are more or less acidic. The vegetation may be sparse or patchy, with numerous rock outcrops. This community is broadly defined and includes examples that may lack pines and are dominated by scrub oak and/or heath shrubs apparently related to fire regime. This community is often surrounded by chestnut oak forest.
Characteristic species include pitch pine (Pinus rigida), chestnut oak (Quercus montana), red oak (Q. rubra), and scarlet oak (Q. coccinea). Other trees may include black cherry (Prunus serotina), red maple (Acer rubrum), gray birch (Betula populifolia), choke-cherry (Prunus virginiana), shadbush (Amelanchier arborea), white pine (Pinus strobus), and a few black gum (Nyssa sylvatica).
Characteristic shrubs include scrub oak (Q. ilicifolia), common juniper (Juniperus communis), blueberry (Vaccinium angustifolium, V. pallidum), sweet-fern (Comptonia peregrina), and black huckleberry (Gaylussacia baccata). Other shrubs include highbush blueberry (Vaccinium corymbosum), sheep laurel (Kalmia angustifolia), mountain laurel (Kalmia latifolia), chokeberry (Aronia spp), and deerberry (Vaccinium stamineum).
Characteristic herbs include Pennsylvania sedge (Carex pensylvanica), poverty-grass (Danthonia spicata), common hairgrass (Deschampsia flexuosa), three-toothed cinquefoil (Potentilla tridentata), and cow-wheat (Melampyrum lineare). Other herbs include bracken fern (Pteridium aquilinum), wintergreen (Gaultheria procumbens), little bluestem (Schizachyrium scoparium), and pink corydalis (Corydalis sempervirens)
Characteristic lichens include various crustose, foliose, and fruticose lichens, such as Cetraria arenaria Cladina spp. and Cladonia spp. Characteristic mosses include hair cap moss (Polytrichum spp.) and pincushion moss (Leucobryum glaucum).
Examples dominated by white pine (Pinus strobus) or other oaks (e.g., Quercus rubra and Q. montana) are tentatively included here until further evaluation warrants the recognition of new community types. |

This small-patch calcareous slope or rocky summit community occurs in southern New England and portions of the northern Piedmont. These xeric, south-facing calcareous slopes or outcrops support small grassland openings characterized by <i>Schizachyrium scoparium</i> and <i>Bouteloua curtipendula</i>. <i>Juniperus virginiana var. virginiana</i> is usually present as a stunted, sparse canopy. Other possible woody associates may include <i>Fraxinus americana, Ostrya virginiana</i>, or <i>Quercus muehlenbergii</i>. Shrubs are sparse but when present may include <i>Celtis occidentalis</i> or <i>Cornus alternifolia</i>. The herbaceous composition is quite diverse and variable among occurrences but often includes such species as <i>Carex eburnea, Anemone cylindrica, Solidago bicolor, Panicum virgatum, Carex pensylvanica, Lespedeza violacea, Lespedeza capitata, Asclepias viridiflora, Asclepias verticillata, Muhlenbergia sobolifera, Sporobolus compositus, Triosteum aurantiacum, Patis racemosa, Pycnanthemum incanum, Sorghastrum nutans, Onosmodium</i> spp., <i>Packera aurea, Packera obovata</i>, and others. This community occurs in association with forests characterized by <i>Quercus muehlenbergii</i>. |

This community occurs as island-like stands in the southern Appalachian Mountains. It occurs on steep ridges and mesic, north-facing slopes above 1830 m (6000 feet) elevation, although it may extend lower on some sites. Occurrences of this community have shallow, rocky soils and are often steep and bouldery with seepage areas. This forest has at least 75% of the canopy coverage composed of <i>Abies fraseri</i>, occurring over a sparse to moderate shrub stratum dominated by deciduous species, a diverse herb stratum, and, typically, a well-developed bryophyte layer. The tree canopy has standing dead stems of <i>Abies fraseri</i> and extensive patches of <i>Abies fraseri</i> saplings in canopy gaps. <i>Oxalis montana, Dryopteris campyloptera</i>, and <i>Athyrium filix-femina</i> are often dominant in the herbaceous stratum. Other characteristic species include <i>Vaccinium erythrocarpum, Sambucus racemosa var. racemosa, Rubus allegheniensis, Rubus idaeus ssp. strigosus, Oclemena acuminata, Eurybia chlorolepis, Clintonia borealis, Solidago glomerata, Rugelia nudicaulis, Ageratina altissima var. roanensis, Chelone lyonii, Circaea alpina ssp. alpina, Streptopus lanceolatus var. roseus, Viola macloskeyi ssp. pallens, Geum radiatum, Huperzia lucidula, Ptilium crista-castrensis, Rhytidiadelphus triquetrus</i>, and <i>Hylocomium splendens</i>. This is a relatively broadly defined community element with much structural and compositional variation. |

This buttonbush swamp occurs in the northeastern United States. These swamps experience prolonged or semipermanent flooding for much of the growing season, with water tables receding below the soil surface only during drought or very late in the growing season. They occur in a variety of environmental settings, including backwater sloughs or oxbow ponds, wet swales in floodplains, pond and lake borders, and small, isolated depressions where water levels recede very slowly, such as those with perched water tables. The substrate is typically loose muck. <i>Cephalanthus occidentalis</i> is dominant and often monotypic. Occasional associates depend on the environmental setting and most often occur in drier areas. They include <i>Vaccinium corymbosum, Rhododendron viscosum, Acer rubrum, Cornus</i> spp. closer to upland borders, or <i>Acer saccharinum, Fraxinus pennsylvanica</i>, and <i>Viburnum dentatum</i> where adjacent to floodplains, or <i>Decodon verticillatus, Chamaedaphne calyculata</i>, and <i>Spiraea alba var. latifolia</i> in more stagnant basins. Herbaceous species tend to be sparse but can include <i>Glyceria canadensis, Dulichium arundinaceum, Carex stricta, Scirpus cyperinus, Thelypteris palustris, Leersia oryzoides, Acorus calamus, Alisma plantago-aquatica, Polygonum</i> spp., <i>Sparganium</i> spp., and floating or submerged aquatic species such as <i>Lemna minor, Potamogeton natans</i>, and <i>Nuphar variegata</i>. Bryophytes, if present, cling to shrub bases and include <i>Warnstorfia fluitans, Drepanocladus aduncus</i>, or <i>Sphagnum fallax</i>. In disturbed areas, these wetland may be invaded by <i>Lythrum salicaria</i>. |

Coreopsis gigantea - Artemisia californica - Eriogonum cinereum Shrubland

This shrubland association occurs on flat to very steep southwest- to northeast-facing slopes at low elevations between 1 and 407 m. It is characterized by a dominance of <i>Coreopsis gigantea</i> with a codominance or subdominance of <i>Artemisia californica</i> and <i>Eriogonum cinereum</i> in the shrub layer. The herbaceous layer may have low cover of <i>Leymus condensatus, Melica imperfecta</i>, and scattered non-native species. The emergent tree layer is typically absent but may include non-native species. |
