The New Jersey Pine Barrens, also known as the Pinelands or simply the Pines, is the largest remaining example of the Atlantic coastal pine barrens ecosystem, stretching across more than seven counties of New Jersey. Two other large, contiguous examples of this ecosystem remain in the northeastern United States: the Long Island Central Pine Barrens and the Massachusetts Coastal Pine Barrens. The name pine barrens refers to the area's sandy, acidic, nutrient-poor soil. Although European settlers could not cultivate their familiar crops there, the unique ecology of the Pine Barrens supports a diverse spectrum of plant life, including orchids and carnivorous plants. The area is also notable for its populations of rare pygmy pitch pines and other plant species that depend on the frequent fires of the Pine Barrens to reproduce. The sand that composes much of the area's soil is referred to by the locals as sugar sand.
