Wood and bark specific gravity of small-diameter, pine-site hardwood in the south

Abstract

Ten small-diameter trees from each of the 22 species (220 trees) were sampled from throughout the southern United States. Mean SG was determined for stem wood and bark and the whole stem, for branch wood and bark and whole branches (to a minimum diameter of 0.05 in.), and for tree wood and bark and the whole tree. Significant differences were determined a) among the species for each tree part measured and b) among the tree parts of each species. The relationship between both stem-wood SG and stem-bark SG and height above ground is plotted by species. There was a significant inverse linear relationship between green MC and SG; with the exception of bark, the ashes contained lower percent moisture than did species of similar SG. Comparison of stem-wood SG values with Wood Handbook values indicates that small-diameter pine-site hardwoods are somewhat denser than larger trees of the same species more typically measured.
