A forest which is located at Sandy Hook, New Jersey, and which is among the best developed Ilex opaca forests on the east coast of the United States, was studied during September and October, 1977. The Point Centered Quarter Method was used to sample arborescent vegetation and density, relative density, frequency, relative frequency, basal area, relative dominance, and importance values were calculated. Holly is dominant and will probably remain dominant because of its isolation, lack of competition, shade tolerance, and tolerance of salt spray.
