Abstract:: Equations are presented for predicting height to crown base (or bole ratio) for fourteen species of trees common to the mixed-conifer zone of southwest Oregon. Nonlinear regression was used to fit a weighted logistic function for each species. The independent variables include height, crown competition factor in larger trees, stand...

Abstract:: Considerable interest has arisen in the relation between timber-selling procedures and the accomplishment of timber-selling objectives on public lands in the West. Procedures of public agencies for measuring and paying for timber by log scale or by lump sum have attracted special attention. There are significant differences in the two...

Creator:: Johnson, James W. and Oregon State University. Forest Research Laboratory
Abstract:: Joints were fabricated from different combinations of untreated and fire-retardant- treated (FRT) Douglas-fir dimension lumber and 3/8-inch plywood. Eight types of fasteners and three fire-retardant treatments were tested. Joint specimens were exposed 2 and 7 years in cold, standard, and warm-humid conditions, then tested in lateral bearing. Best overall performance...

Creator:: Ritchie, Martin W., Hann, David W., and Oregon State University. Forest Research Laboratory
Abstract:: Equations for predicting individual-tree height growth per 5-year period are presented for Douglas-fir, white fir, grand fir, ponderosa pine, sugar pine, and incense-cedar growing in the mixed-conifer zone of southwest Oregon. The data used to develop the equations came from 3,648 trees sampled from 391 stands in the study area....

Creator:: Zumrawi, Abdel Azim M. A., Hann, David W., and Oregon State University. Forest Research Laboratory
Abstract:: This paper presents equations developed to predict the height to live crown base of six species in the central western Willamette Valley of Oregon. Weighted nonlinear regression was used to fit a separate logistic equation for each species. The predictor variables are total tree height, crown competition factor in trees...
