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...

The influence of moisture and temperature on the preservation of Douglas-fir pollen by freeze-drying

Creator:

Livingston, Gordon K., 1938-

Abstract:

Forest crop improvement through the application of genetic principles has been recognized as an important factor in forest management. The use of hybridization and selective breeding in forest tree improvement points to the urgency of maintaining "pollen banks" of superior trees. The objective of this study was to determine the...

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...
