The top ten species in New Jersey in terms of standing biomass are pitch pine, red maple, white oak, northern red oak, chestnut oak, yellow- poplar, scarlet oak, sweetgum, white ash, and black oak. These species account for 69.1% of the total aboveground biomass and 67.7% of the total merchantable volume. For merchantable wood volume, the species with the smallest percent change was northern red oak -0.1%, while the largest percent change was with red maple -7.5%. For total aboveground biomass, the species with the smallest percent change was scarlet oak 4.1%, while the largest percent change was with pitch pine 30%. For sawlog wood volume, the species with the smallest percent change was white ash 0.5%, while the largest percent change was with red maple -15.5%. For merchantable bole biomass, the species with the smallest percent change was chestnut oak 0.3%, while the largest percent change was with white ash -16.2%. For stump wood and bark biomass, the species with the smallest percent change was scarlet oak -1.2%, while the largest percent change was with white ash -49.9%. For top and limb biomass, the species with the smallest percent change was white ash 4%, while the largest percent change was with pitch pine 177%.
