Atlantic coastal pine barrens

The Atlantic coastal pine barrens, now a rare temperate coniferous forest ecoregion of the Northeast United States, is distinguished by unique species and topographical features (coastal plain ponds, frost pocket), generally nutrient-poor, often acidic soils, and a pine tree distribution once controlled by frequent fires. == Setting == This ecoregion once stretched from North Carolina to Nova Scotia but now covers a disjunct area with three remaining large contiguous areas: the New Jersey Pine Barrens on the coastal plain of New Jersey; the rapidly diminishing forests of southern Long Island in New York State; and the Massachusetts Coastal Pine Barrens, which stretches from Plymouth, Massachusetts to Cape Cod and the Islands of Martha's Vineyard and Nantucket.
