Pine barrens are unique ecosystems characterized by sandy, acidic soils and a predominance of pine trees, particularly the Eastern White Pine and Pitch Pine. These areas often experience low nutrient levels, which limits the growth of many other plant species. The landscape is typically open, with scattered shrubs and grasses, making it a distinct habitat. These ecosystems are important for biodiversity, providing homes for various wildlife, including the endangered New Jersey Pine Barrens Tree Frog. Pine barrens also play a crucial role in water filtration and carbon storage, helping to maintain ecological balance in their regions.
