Tests of some chemical herbicides in controlling brush, weed trees, and grasses on the McDonald Forest

Creator:

Heuschkel, Dexter Gouldin

Resource Type:

Masters Thesis
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
Formation of quality classes for secondgrowth Douglas-fir logs based on lumber grade recovery

Creator:

Parks, Walter Howard

Resource Type:

Masters Thesis
Comparative efficiency of the wedge prism method and the circular plot method in estimating volumes of Douglas-fir stands

Creator:

Richardson, James Hollins

Resource Type:

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
The construction of stand aerial photo-volume tables for second-growth Douglas-fir

Creator:

Lundgren, John Wollan

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...
