Classification
Scientific Name: Northern Atlantic Coastal Plain Pitch Pine Barrens
Unique Identifier: CES203.269

Summary: This system comprises a group of dry pitch pine woodlands and forests of deep sandy soils ranging from Cape Cod (Massachusetts) south through Long Island (New York) and the famous Pine Barrens of the New Jersey Coastal Plain, with occasional occurrences north to southernmost Maine and south to the Anacostia watershed (Maryland). The vegetation is characterized by a tree canopy of Pinus rigida with a tall-shrub layer dominated by Quercus ilicifolia and a low-shrub layer characterized by Vaccinium pallidum and/or Vaccinium angustifolium. The system is heavily influenced by fire, the composition and structure of its components varying with fire frequency. In general, tree oaks are more prevalent in those stands having a longer fire-return interval; fire frequencies of 8-10 years foster the growth of "pine plains," i.e., dwarf pine stands 1 m in height. Pine barrens with a history of more-or-less biennial burns for lowbush blueberry production may have very few trees and be characterized as sandplain grasslands. Dwarf-shrubs such as Arctostaphylos uva-ursi, Vaccinium angustifolium, Vaccinium pallidum, and Hudsonia ericoides typify the field layer of pine plains and sandplain grasslands. Schizachyrium scoparium is the most common grass (in close proximity to the coast, it may be represented by its close relative Schizachyrium littorale).

Scrub oak stands may occur without pine cover, particularly in low-lying areas that do not intersect the water table, where cold-air drainage inhibits pine growth. North of the glacial boundary, heathlands characterized by Arctostaphylos uva-ursi, Corema conradii, and Morella pensylvanica, and grasslands characterized by Schizachyrium littorale, Schizachyrium scoparium, and Danthonia spicata occur as small (or occasionally large) patches. The Pine Barrens of New Jersey are very similar in structure and composition to those north of the glacial boundary but are characterized by additional species, such as Quercus marilandica, Quercus stellata, Pyxidanthera barbulata, Leiophyllum buxifolium, and others. Where the water table is close to the surface, pitch pine lowland vegetation (described as a separate system) occurs.

Classification Approach: International Terrestrial Ecological Systems Classification (ITESC)

Classification Comments: This system includes the New Jersey Pine Barrens, the uniqueness of which has long been recognized, and the system is well-studied and summarized in a number of recent treatments (Forman 1979, Buckhholz and Good 1982, Gibson et al. 1999).
