The New Jersey Pine Barrens stretch across more than seven counties of New Jersey.
The name refers to the area's sandy, acidic, nutrient-poor soil.
The Pinelands are mostly rural and undisturbed despite being so close to the cities of Philadelphia and New York City.
The territory helps recharge the 17 trillion-gallon Kirkwood-Cohansey aquifer, which is some of the purest water in the US.
