A comparison of the harmonized-curve and the combined variable methods of cubic foot volume table construction

Creator:

Berry, Dick Wallace, 1914-

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
A comparative economic analysis between log scaling practices

Creator:

Lewis, Charles Stewart

Abstract:

Many centers of population in the Pacific Northwest are dependent upon employment in the forest based industries. Mary of these timber dependent communities look to the public forests for their raw wood requirements. In some localities the installed capacity has outstripped the local wood supply. This necessitates reaching into other...

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
A comparative study of three log rules commonly used in the Pacific Northwest, U.S.A.

Creator:

Paixao, Julio De Castro

Abstract:

A comparative study was done on data collected by Weyerhaeuser Company on l,6144 second-growth Douglas-fir, Pseudotsuga menziesii, trees. The variable used in the study was the percent difference, positive or negative, between the volumes given by each of three different log rules and the standard tree volumes determined by Weyerhaeuser...

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
Nutrient losses and nitrogen mineralization on forested watersheds in Oregon's Coast Range

Creator:

Miller, James H.

Abstract:

Nutrient losses of the biologically responsive anions, nitrate and bicarbonate together with the major cations, were monitored on 14 small watersheds in Oregon's Coast Range and evaluated in relation to management-induced disturbance. Mixed forests of Douglas-fir and red alder had dominated these high-nitrogen sites prior to treatment. A paired-watershed experimental...

Dissertation
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,...

Masters Thesis
Nonindustrial forests, public policy and long-term timber supply in the South

Creator:

Brooks, David J.

Abstract:

Forest Service projections of the long-term supply and demand for forest products indicate that increasing importance will be placed on the supply behavior of nonindustrial private forest owners in the South. The inventory model on which these projections are based may produce biased estimates of southern timber production, however, as...

Dissertation
Sensitivity of TRIM projections to management and stocking adjustment assumptions

Creator:

Alexander, Susan J.

Abstract:

The Timber Resource Inventory Model (TRIM) is a computer model used by the U.S.D.A. Forest Service in assessing the state of the Nation's forest resources and the forests' probable future conditions. TRIM is a yield table projection system designed and developed to model forest inventory changes over time in response...
