A quantitative analysis of log volume concepts and product derivatives

Creator:

Smith, Douglas Sterling

Abstract:

One of the most important challenges facing foresters is the development of a raw material measurement system designed to give a complete inventory of log volume and to assist in planning the complete management of log production. This paper introduces a concept of production analysis in terms of solid fiber...

Masters Thesis
An analysis of design and technique of cluster point sampling in coastal Alaska old-growth forests

Creator:

LaBau, Vernon J.

Abstract:

This study was a test of eight basal area factors and five point sampling cluster patterns in a computer oriented sampling study of coastal Alaska old-growth spruce-hemlock stands. It was an attempt to learn which basal area factor and which type of point sample cluster pattern should be used in...

Masters Thesis
Calculation of tree volume and surface area by the height-accumulation method

Creator:

Arney, James Douglas, 1941-

Abstract:

This study was initiated to determine the accuracy and limits of the height-accumulation method of measuring tree volume and surface area for Pacific Northwest second-growth trees. Thirty trees were selected from various thinning treatments in a 55 year old Douglas-fir forest. Each tree was measured with the highly accurate Barr...

Masters Thesis
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...

Masters Thesis
A computer simulation study of the relative efficiency of several forest sampling techniques as influenced by the spatial distribution of trees found in five major forest types of the Pacific Northwest

Creator:

Payandeh, Bijan

Abstract:

This study was initiated to determine the relative efficiency of systematic, stratified and simple random sampling for crown area and tree frequency estimation of five of the major forest types found in the Pacific Northwest. Several of the more common methods of estimating spatial distribution coefficients were evaluated. Finally the...

Diameter yield tables versus site-index yield tables for western hemlock

Creator:

Newport, Carl A., 1924-

Resource Type:

Masters Thesis
A preliminary investigation into the use of the tarif system and three tree selection methods for obtaining Douglas-fir stand and stock tables from large-scale aerial photography

Creator:

McCadden, Richard Jay

Abstract:

As a preliminary step toward the establishment of a 70 mm. aerial photo timber inventory system capable of generating accurate stand tables, stock tables, and gross volume estimates, this project focuses on the development of a system which (1) eliminates the need to measure tree height on the photos through...
