Operational Efficiency in Forestry
Author: B. SundbergPublisher: Springer Science & Business Media
ISBN: 9401705046
Category : Technology & Engineering
Languages : en
Pages : 229
Book Description
It is our conviction - based on many years of teaching and practical experience - that professional skill in forestry will develop more rea dily and more efficiently if forestry students are presented with a clear understanding, at an early stage, of the impact of the physical factors that both enhance and inhibit forestry activities. Tnis know ledge is best aquired by adressing the physical world of forestry with a set of analytical tools through which an almost infinite number of variables can be listed in order, be measured and their interaction be explored and resolved. This is the main purpose of this joint effort, presented in two volumes, Part I and Part II. Part I is analytic, written as a basic text for undergraduates in cour ses such as logging, transport, forest engineering and even forest ma nagement. It deals with the fundamentals of technology in forestry as determined by the physical environment. Briefly it can be visualized as the application of forestry wi thin the parameters: space, time and energy. Forestry is a process with a long time horizon. Free solar energy creates biomass which, with the aid of other forms of energy, is converted into products and services. A knowledge of the dependecies and interactions is indiGpensible for the forestry profession. The analytic approach serves two purposes: to bring about a clear un derstanding of the real world of forest and to develop tools through which efficiency and productivity can be explored and improved.
Sampling Methods for Multiresource Forest Inventory

Category : Nature
Languages : en
Pages : 496
Book Description
Designed to aid readers in gathering the most reliable quantitative information on forests for the least cost. Thoroughly explains the interrelationships between sampling strategies; discusses forestry techniques of efficient tactics; examines new developments in statistics having immediate applications in forestry and describes related developments that should have relevance in the future. Includes practical methods for dealing with forest data such as tree number, height, diameter and marketable wood. Also contains problem sets.
Operational Efficiency in Forestry

Book Description
It is our conviction that professional skill in forestry will develop more readily and more efficiently if forestry students are presented with a clear understanding of the im pact of the physical factors that both enhance and inhibit forestry activities. Part I is analytic, written as a basic text for undergradu ates in courses such as logging, transport, forest engineer ing and even forest management. It deals with the fundamen tals of technology in forestry as determined by the physical environment. The analytic approach serves two purposes, to bring about a clear understanding of the real world of the forest and to develop tools through which efficiency and productivity can be explored, understood and improved. The principal author of this volume was Prof. Ulf sundberg. Part II discusses in some detail a wide variety of practical problems encountered by foresters. It describes harvesting systems and the principles of management and control of forest operations. The influence of the forest on operations is described at length, the terrain, topography, forest soils as well as the engineering characteristics of trees and forest stands. It also considers the impact of oper ations on the forest. The principal author of this volume was Dr. Ross Silversides. Chapters 11, 12 and 13 were written by-Prof. Sundberg.
