Atlantic, Burlington, and Camden Counties
Coordinates: N 39.71434
W 74.65471
Pinelands: New England / Mid-Atlantic Coast

Area: 191,166 Acres     

Habitat: Mixed upland forest, freshwater wetlands and fallow cranberry bogs

Site Description: Wharton State Forest is the largest single tract of land within the New Jersey State Park System and is a major component of the largest remaining contiguous forest blocks in the state. Located in the Pinelands Region, the area is composed of mature pine forest, oak forest, pine/oak forest, Atlantic white cedar (Chamaecyparis thyoides) swamps, Tupelo/Maple swamps and fallow cranberry bogs. The site includes the headwaters of the Mullica and Batso Rivers and the southern headwaters of Rancocas Creek. Friendship Bogs and several privately owned parcels are also included in this site.

Birds: The Wharton State Forest IBA supports a wide variety of bird species throughout the year. State-endangered Red-shouldered Hawks breed within Wharton State Forest. The site also supports characteristic species of scrub-shrub habitat and mixed upland forest. Significant concentrations of breeding Pine Warblers, Ovenbirds, Prairie Warblers and Eastern Towhees are consistently observed here. Additional notable concentrations include Black-and-white Warblers, Gray Catbirds, Scarlet Tanagers and Wood Ducks. The scrub-shrub areas along Caranza Road near Friendship Bogs provides important breeding habitat for Common Nighthawks, Whip-poor-wills and Chuck-will’s-widows. The Research Department of New Jersey Audubon Society has identified this site as an important stopover area for songbirds during spring and fall migration through its Doppler Radar migration study, “Oases Along the Flyway.”

Conservation: The majority of this site is protected from development. Protection of privately-owned lands can be achieved by promoting landowner incentives for protecting and managing habitat and by prioritizing parcels for acquisition. Control of invasive species, including southern pine beetles and gypsy moths, can be implemented with appropriate methods. Forests should be protected as large, contiguous patches while maintaining a diversity of Pinelands community types including early successional habitats. Illegal off-road vehicle use is also a major threat that requires control through increased law enforcement. Other threats include wildfire and habitat loss through succession to forested communities.
