This is modeledmap a distributiononbased current and is data nota substitute for field inventory. based Contact © Kathleen Strakosch Walz (New Jersey Natural Heritage Program) Description: A dry, fire-adapted forest with a variable canopy of pitch pine, a tall-shrub layer dominated by scrub oak, and a low- shrub layer characterized by blueberry and other heaths. Other oaks (scarlet, black, chestnut, white) are also sometimes present. Composition and structure vary with fire frequency. In general, tree oaks are more prevalent in those stands having a longer fire-return interval, while fire frequencies of eight to ten years foster the growth of "pine plains," dwarf pine stands one meter in height. Dwarf-shrubs such as lowbush blueberry, bearberry and golden-heather typify the field layer of pine plains. Scrub oak stands may occur without pine cover, particularly in low-lying areas State Distribution: MA, NJ, NY, RI where cold-air drainage inhibits pine growth.

    Flora of the Carolinas, Virginia, and Georgia, Working Draft of 17 March 2004 -- ERICACEAE ERICACEAE (Heath Family) A family of about 107 genera and 3400 species, primarily shrubs, small trees, and subshrubs, nearly cosmopolitan. The Ericaceae is very important in our area, with a great diversity of genera and species, many of them rather narrowly endemic. Our area is one of the north temperate centers of diversity for the Ericaceae. Along with Quercus and Pinus, various members of this family are dominant in much of our landscape.

  • Vanishing Pine Barrens of the Washington DC Vicinity
    Vanishing Pine Barrens Communities of the Washington, D.C. Vicinity Maryland Native Plant Society 2016 Annual Fall Conference September 17, 2016 Rod Simmons The Southern Megalopolis The Washington-Baltimore region is probably the most geologically and floristically diverse area in the eastern United States. Urban and suburban areas in and around these large old cities also typically contain the largest number and variety of old-age trees and remnant stands. Also, in close proximity to the Megalopolis are a surprising number of extensive, high quality natural communities, i.e., Patuxent Research Refuge, Beltsville Agricultural Research Center, Greenbelt Park, Chapman State Park, Mattawoman Wildlands, etc. Image courtesy Jim Long Photo courtesy USGS Photo by Gary P. Fleming The Fall Line, or “Fall Zone”, is a first order physiographic boundary between the Piedmont Plateau on the west and the Atlantic Coastal Plain to the east. This zone of transition, where the hard, crystalline bedrock of the Piedmont descends under the soft sediments of the Coastal Plain, is defined by deeply entrenched stream valleys that commonly form gorges, waterfalls, and rapids. It was also the farthest navigable limits upstream for oceangoing vessels, thus most of the old, large cities along the Atlantic seaboard are situated along it. The southernmost extension of New Jersey Pine Barrens communities occur in the Western Shore Uplands Region of Maryland, as well as relatively smaller outliers in the inner Coastal Plain of the District of Columbia and northeastern Virginia. Pitch Pine (Pinus rigida) is the dominant and characteristic tree of the New Jersey Pine Barrens, where it occurs on sandy soils in dry to moist conditions.

  • Wild Vegetation of West Virginia Dry Pines
    Wild Vegetation of West Virginia Revised 7 February 2020 Comments and Questions? Contact [email protected] Dry Pine and Pine-Oak Forests and Woodlands Driving across West Virginia in winter, the evergreen trees pop out, no longer hidden by their deciduous tree associates. At high elevations they may be spruce, in moist areas they may be hemlocks, in drier areas they are often pines. Pines are adapted to sunny habitats along roadsides, but away from roads they dominate natural forests and woodlands in some of our most dramatic landscapes. Ecological Description: Dry Pine and Pine-Oak Forests and Woodlands are a diverse group of natural communities united by their dominance or codominance by species of pine (Pinus). Native WV pines include shortleaf pine (Pinus echinata), Table Mountain pine (Pinus pungens), red pine (Pinus resinosa), pitch pine (Pinus rigida), white pine (Pinus strobus), and Virginia pine (Pinus virginiana). Depending on the association, the canopies of these forests and woodlands range from open to closed and from nearly pure evergreen to mixed evergreen-deciduous. Canopy height is also variable, ranging from pygmy pitch pine forests <5 meters tall to mixed forests with white pines >40 meters tall towering over their oak companions. Common deciduous tree canopy associates include white oak (Quercus alba), scarlet oak (Quercus coccinea), chestnut oak (Quercus prinus), red oak (Quercus rubra), black oak (Quercus velutina), black gum (Nyssa sylvatica), sourwood (Oxydendrum arboretum), and red maple (Acer rubrum). Shrub layers in many stands are dominated by heaths, including mountain laurel (Kalmia latifolia), black huckleberry (Gaylussacia baccata), and blueberries (Vaccinium angustifolium, Vaccinium pallidum).

  • HAMPTON BAYS Corridor Strategic Plan GEIS and Cumulative Impact of Build-Out Study
    HAMPTON BAYS Corridor Strategic Plan GEIS and Cumulative Impact of Build-Out Study Part V: RESOURCES & ATTACHMENTS 6. Definitions of Ecological Communities Found in Hampton Bays Terrestrial System — Forested Uplands • Pitch Pine-Oak Forest Edinger et al. (2002) describes pitch pine-oak forests as follows: There are at least two potential regional variants of pitch pine-oak forests. These include the typical coastal variant on Long Island and the inland variant of upstate New York. The coastal variant pine-oak forest which is applicable to the Hamlet of Hampton Bays, consists of native mixed woodlands that are commonly found on well-drained, sandy soils of glacial outwash plains or moraines. The dominant trees are pitch pine (Pinus rigida) mixed with one or more of the following oaks: scarlet oak (Quercus coccinea), white oak (Q. alba), red oak (Q. rubra), or black oak (Q. velutina). The relative proportions of pines and oaks are quite variable within this community type. At one extreme are stands in which the pines are widely spaced amidst the oaks, in which case the pines are often emergent above the canopy of oak trees. At the other extreme are stands in which the pines form a nearly pure stand with only a few widely spaced oak trees. The shrublayer is well-developed with scattered clumps of scrub oak (Quercus ilicifolia) and a nearly continuous cover of low heath shrubs such as blueberries (Vaccinium pallidum, V. angustifolium) and black huckleberry (Gaylussacia baccata). The herbaceous layer is relatively sparse. Characteristic species are bracken fern (Pteridium aquilinum), wintergreen (Gaultheria procumbens), and Pennsylvania sedge (Carex pensylvanica).

This is modeledmap a distributiononbased current and is data nota substitute for field inventory. based Contact © Jennifer Case (The Nature Conservancy, Pennsylvania) Description: A fire-adapted system of Northeast glacial sandplains, typically an open woodland but sometimes including patches of closed-canopy forest and herbaceous openings. Pitch pine is the usual dominant; red oak, white pine, and gray birch are common associates. A tall-shrub layer of scrub oak or dwarf chinkapin oak is characteristic, as is a low-shrub layer of heath and sweetfern. Small changes in elevation create pockets with saturated soil, where shrubs such as hazelnut, buttonbush, highbush blueberry, and alder form dense cover. Grassy areas dominated by little bluestem, native lupine, and other forbs, provide habitat for rare invertebrates like the frosted elfin.
