Estimation of Diameter at Breast Height from Stump Diameter for Lodgepole Pine

摘要

Equations to estimate diameter at breast height outside bark from the stump diameter outside bark are presented for 13 lodgepole pine sites. The data came from three National Forests in Montana. General equations are also given for two varieties of lodgepole pine from data collected across the range of the species in North America. Simple linear regression methods were used. As an application, a procedure for obtaining tree volume is described.
