The New Jersey Pine Barrens, or Pinelands National Reserve (PNR), is a vast and unique ecosystem comprising approximately a 938,000-acre area of southern New Jersey. It spans portions of seven counties (Atlantic, Burlington, Camden, Cape May, Cumberland, Gloucester, and Ocean), and all or part of 56 municipalities. It is home to dozens of rare plant and animal species, and the Kirkwood-Cohansey aquifer system, which contains an estimated 17 trillion gallons of water.
The New Jersey Water Science Center has had a long tradition of research covering this natural wonder. Studies by staff scientists address a wide range of environmental topics, including Pinelands water quality, hydrology, watershed and landscape assessments, and aquatic and wetland ecology.
