This study included 14 species of hardwoods and a total of 325 trees. Ten species were oak, which were divided into a red oak group (seven species) and a white oak group (three species). The red oak group had an average bulk density of 80.7 lb/ft³, and the white oak group had an average bulk density of 79.2 lb/ft³. A significant difference was found between the groups, as were significant differences between species within each group. Southern red oak (<i>Quercus falcate</i>) had the highest value (83.0 lb/ft³), and white oak (<i>Quercus alba</i>) had the lowest (77.0 lb/ft³). Three hickory types had an average bulk density of 79.4 lb/ft³. Sweetgum (<i>Liquidambar styraciflua</i>) had a bulk density of 78.3 lb/ft³. 收起
