A Key for the Forest Service Hardwood Tree Grades
A dichotomous key organizes the USDA Forest Service hardwood tree grade specifications into a stepwise procedure for those learning to grade hardwood sawtimber. The key addresses the major grade factors, tree size, surface characteristics, and allowable cull deductions in a series of paired choices that lead the user to a decision regarding tree grade. Subtle grading rules, previously presented as footnotes to the major specifications, are included in the key. It simplifies the process so that the beginner can learn the system quickly, without detailed instruction from experienced tree traders. North. J. Appl. For. 3:19-22, Mar. 1986.
