Description: The linear relationship of inside to outside bark diameter at breast height provides a basis for estimating diameter inside bark from diameter outside bark. Estimates of diameter inside bark and past diameter outside bark are useful in predicting growth and yield. During field seasons 1979-1982, data were obtained from stem analysis of 931 trees in young-growth stands of the mixed-conifer type on the westside Sierra Nevada of California. Species included were coast Douglas-fir, California white fir, incense-cedar, sugar pine, ponderosa pine, and Jeffrey pine. This note provides equations for estimating inside bark diameters, double bark thickness, and past outside bark diameters for each of the species studied.
