Tree value conversion standards revisited
1991
DeBald, Paul S. | Dale, Martin E.
"Updated tree value conversion standards (TVCS) are presented for 12 major hardwood species of the central hardwood forest. TVCS measure a tree's worth in dollars based on the quantity and quality of its expected yield of 414 (I-inch) lumber. The updated standards-developed for each species by butt-log grade, merchantable height, and diameter at breast height-reflect the changes in lumber prices and in conversion costs which have occurred since 1976 when the original TVCS were published."
