Abstract

For a more efficient use of the hardwood forest resource, tables were developed for estimating the weight of sawtimber tops, a major portion of logging residue. Regressions were developed for green and dry total treetop weight and treetop weight in material greater than 3 inches dob (diameter outside bark) for each of three species groups: soft hardwoods, hard hardwoods, and mixed hardwoods. Estimates of treetop weights (green) ranged from 763 pounds for an 1 1-inch dbh (diameter at breast height) tree to 4,165 pounds for a 26-inch dbh tree. Moisture content averaged 62 percent (oven-dry basis), and the average percent bark (green-weight basis) was 23.
