Bulk density of bottomland hardwoods in East Texas and West Louisiana

To assist in merchandising certain hardwood trees growing in East Texas and West Louisiana hardwood bottomlands, two measures of bulk density were determined for red oak species, white oak species, and sweetgum trees. One value was the weight (in pounds) of a cubic foot of green wood, and the other value was the green weight of a cubic foot of wood and bark. Average bulk densities were calculated by five classes of diameter at breast height (DBH) according to five 9-foot stem segment positions above the stump up to 45 feet above the stump. In general, for a given species and DBH class, stem position did not significantly influence bulk density values, however bulk density values tended to increase with higher positions on the stem. Likewise, for a given species and stem position, DBH class usually did not significantly affect bulk density, but weight values tended to be heavier with increasing tree size. Bulk density was different between the three species.
