The top ten species growing in National Forests in Region 8 (Southern) in terms of standing biomass are loblolly pine, chestnut oak, white oak, shortleaf pine, northern red oak, red maple, yellow- poplar, slash pine, scarlet oak, and longleaf pine. These species account for 66.7% of the total aboveground biomass and 68.8% of the total merchantable volume. For merchantable wood volume, the species with the smallest percent change was longleaf pine 1.1%, while the largest percent change was with shortleaf pine 8.5%. For total aboveground biomass, the species with the smallest percent change was loblolly pine 0.8%, while the largest percent change was with red maple 29.4%. For sawlog wood volume, the species with the smallest percent change was longleaf pine -0.4%, while the largest percent change was with northern red oak 9.1%. For merchantable bole biomass, the species with the smallest percent change was white oak 0.5%, while the largest percent change was with red maple 14.9%.
