DescriptionHardwood trees have for many years been measured in such a way that tree volume could be estimated; and in recent years the prediction of tree quality by using tree grades has become of interest to owners, sellers, and buyers of timber. Several tree-grading systems have been developed, but none has been publicized and used on a widespread scale. The Forest Service recently adopted and approved interim hardwood tree grades for factory lumber. The specifications for these tree grades and the associated lumber grade voluies for yellow birch, red maple, and black oak are presented here.
