Warren Grove Recreation Area, acquired from the National Park Service in the 1970s, is 617-acres of undeveloped wilderness located west of the town of Warren Grove. WGRA has several unique historic and natural features: Part of the Little Pine Plains, a globally rare forest community, where the mature trees have an average height of 8-10 feet, lies within its boundaries. A large population of the state endangered broom crowberry (Corema conradii) thrives along the edges of some roads and in open fields. The historic 1686 Keith Line which first divided the Province of New Jersey into the Provinces of East and West Jersey bisects the WGRA. And sharing the Keith Line are the boundaries of Ocean and Burlington counties and the boundaries of five municipalities all of which come together within less than an eighth mile of each other. WGRA is perfect for passive recreation like birding, hiking and enjoying the natural beauty and serenity of the Pinelands.
The central region of the Pine Barrens contains several areas of pine and oak forest that resemble the surrounding forests with one major exception: from a standing position, one can gaze over the top of the tree canopy. The Pine Barren Plains, known locally as the Pygmy Forest, contains trees that may attain a height of only about four feet at maturity. New Jersey contains the world's largest acreage of this globally rare forest community, which can be seen within portions of Warren Grove Recreation Area known as the Little Pine Plains. Many researchers believe that this unique stunted forest ecosystem is partly the result of the fire ecology of the Pinelands.
The recreation area, as well as the undeveloped wilderness, is open for hiking.
Warren Grove Recreation Area is open for passive recreation including horseback riding and nature/ecology study. Access into the recreation area is via several sand roads and old woods roads through the area but no marked trails currently exist.
