The plant community types on three tracts within the Burden Hill Forest, a distinctive outlier of the New Jersey Pine Barrens, are described and classified. While these tracts consist largely of a general pine barrens type, they display a number of significant differences from the main body of the Pine Barrens. These differences include additional forest plant community types previously undescribed for New Jersey, higher heterogeneity of community types and woody plant diversity, and the presence of several unusual or rare species including Castanea pumila (Allegheny Chinquapin).
