Converting international ¼ inch tree volume to Doyle

Informally Refereed

Abstract

An equation for converting Mesavage and Girard's International ¼ inch tree volumes to the Doyle log rule is presented as a function of tree diameter. Volume error for trees having less than four logs exhibited volume prediction errors within a range of ±10 board feet. In addition, volume prediction error as a percent of actual Doyle tree volume was generally less than 10 percent for all trees and less than 5 percent for trees larger than 20-inch diameter at breast height (d.b.h.) This equation was developed for those wanting a more accurate method of converting standard inventory estimates of average volume to an alternative log rule.
