The top ten species in West Virginia in terms of standing biomass are chestnut oak, red maple, yellow- poplar, white oak, northern red oak, sugar maple, black oak, American beech, black cherry, and pignut hickory. These species account for 73.2% of the total aboveground biomass and 71.3% of the total merchantable volume. For merchantable wood volume, the species with the smallest percent change was sugar maple -0.5%, while the largest percent change was with black cherry -11.2%. For total aboveground biomass, the species with the smallest percent change was yellow- poplar -1.3%, while the largest percent change was with red maple 23.3%. For sawlog wood volume, the species with the smallest percent change was chestnut oak -0.1%, while the largest percent change was with American beech -12.3%. For merchantable bole biomass, the species with the smallest percent change was sugar maple 0.4%, while the largest percent change was with American beech -12.9%. For stump wood and bark biomass, the species with the smallest percent change was white oak 1.5%, while the largest percent change was with black cherry -32.9%. For top and limb biomass, the species with the smallest percent change was yellow- poplar 5.8%, while the largest percent change was with northern red oak 123.3%.
