Growth growing-stock relationships in young Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco)

Creator:: Sales Luis, Jaime Fernando
Abstract:: In the thinning theory, the hypothesis that the stand growth is unaffected by the density over a broad range of densities is generally accepted today. In this study three different measures of stand density were used in basal area growth and volume growth multiple regressions in even-aged managed stands, searching...

A proposed sampling technique and electronic data processing program for reproduction surveys in forest plantations

Creator:: Schutt, Walter W.
Abstract:: The purpose of this thesis is to determine if the Oregon State Forestry Department's stocking survey system can be applied to planted acres as well as to seeded acres. Two computer programs were developed into a primary program. One produced a new stocking curve adapted to hand planting patterns, and...

Effects of stand density on site index in thinned stands of Douglas-fir in the Pacific Northwest

Creator:: Zumrawi, Abdel Azim M. A.
Abstract:: In site index studies, the hypothesis that height growth of most conifers is independent of stand density is commonly accepted. However, some studies have shown height growth to be influenced by density particularly on medium to poor sites. In this study two locations representing a high quality site (Hoskins area,...

An analysis of the weighted least squares technique as a method for the construction of tree volume tables

Creator:: Munro, Donald Deane
Abstract:: The purpose of this thesis was to investigate the use of weights in least squares regression volume table construction and thereby to determine the importance of the assumption of homogeniety of tree volume variance. Several weighted and unweighted linear regression equations were investigated using data from 340 Douglas-fir Pseudotsuga menziesii...

Yields of repeated high and low commercial thinnings of immature coastal Western hemlock

Creator:: Hilt, Donald E.
Abstract:: Commercial thinnings in a 50-year-old stand of nearly pure, well stocked, even-aged western hemlock (Tsuga heterophylla) on the Hemlock Experimental Forest near Hoquiam, Washington, began in 1952 and ended in 1968. The experiment consisted of two replications of four different thinning treatments, high and low thinning, both at frequent and...

The use of a three-stage sample to estimate the effect of commercial thinning on the growth of two stands of Douglas-fir

Creator:: Graham, Joseph Nelson
Abstract:: A three stage sale was taken of two high-site, second growth Doug1as-fir (Pseudtsuga menziesii) stands located in the extreme northwestern portion of the Oregon Coast Range. Permanent plots were established during the first stage variable-plot cruise. A Hartley- List sample, taken from the first stage Douglas-fir in trees, selected second...

Growth and yield of unmanaged stands of quaking aspen on the upper Navajo River in the Rocky Mountains of southwest Colorado

Creator:: Clendenen, Gary Wayne
Abstract:: An average stand diameter yield table and a diameter growth per decade table are presented for unmanaged stands of quaking aspen in southwest Colorado. The yield table presents yields per tree for the following utilization standards: 1. total cubic-foot volume minus the stump, 2. cubic-foot volume to a 4-inch top,...
