This book was released on 2001-11-30 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume comprises eighteen papers dealing with the theory and application of modern decision-making and management planning of multiple use of forestry and other natural resources in the landscape. Generally, an economic approach is used as implemented by operations research methods, but broader contexts are applied too, e.g. ecosystem management, discounting, preference analysis and policy formulation. The volume is aimed at researchers, students and practitioners in management of forestry and other natural resources.

Available in PDF, EPUB and Kindle. Book excerpt: The large-scale application of new silvicultural systems has become a political reality in many parts of the world. This involves a gradual transformation of traditional silvicultural practice towards Continuous Cover Forestry, also known as near-natural forest management, favouring mixed uneven-aged stands, site-adapted tree species and selective harvesting. Selective harvesting systems have a long tradition. Specific CCF-related resource assessment, forecasting and sustainable harvest control techniques have been developed, but details about their use are not widely known. The objective of this volume is to present state-of-the-art research results and techniques relating to CCF management with an emphasis on systems engineering and modelling. Using a very simple classification based on the development of timber volume over age or time we may distinguish two types of sustainable forest management systems. Rotation forest management (RFM) systems, characterized by standard silvicultural treatments and repetitive cycles of clearfelling followed by planting; and continuous cover forestry (CCF) systems which are characterized by selective harvesting and natural regeneration, resulting in uneven-aged structures and frequently also in multi-species forests. The distinction is usually the result of decisions relating to the cost of timber harvesting, simplicity of management, or various intangible benefits. The oldest and most perfect examples of CCF systems are the so called plenter selection forests found in France, Switzerland, Slowenia and Germany. Today, CCF systems are encountered in various regions of Europe, North America and in some tropical and sub-tropical forests of South Africa, Asia and South America.

Available in PDF, EPUB and Kindle. Book excerpt: A density-dependent matrix growth model of uneven-aged loblolly pine stands was developed with data from 991 permanent plots in the southern United States. The model predicts the number of pine, soft hardwood, and hard hardwood trees in 13 diameter classes, based on equations for ingrowth, upgrowth, and mortality. Projections of 6 to 10 years agreed with the growth of stands between the last two inventories. In 300-year simulations of undisturbed growth, softwood species were replaced by hardwoods, in accord with previous knowledge. Soft hardwood species became dominant on good sites and hard hardwoods on poor sites. Basal area oscillated over time, converging slowly towards a steady state. Changes in tree size diversity were correlated positively with basal area. Without disturbance, species diversity would decrease. For economic analysis, equations were developed to predict total tree height, sawlog length and volume, pulpwood volume, and volume of top sawtimber, as functions of tree diameter and stand basal area. Simulations of three cutting regimes showed that management would lead to a steady state faster than would natural growth. Management aimed at maintaining the current average distribution would result in size and species diversity similar to that of an unmanaged stand. From a financial point of view, the q-factor guide and a 13-in.- (330-mm-) diameter-limit cut would be superior to the average current management regime. The diameter-limit regime would have the greatest effect on lowering tree size diversity and an effect on species diversity similar to that of the q-factor guide. A computer program, SOUTHPRO, was developed to simulate the effects of other management alternatives.

Available in PDF, EPUB and Kindle. Book excerpt: In recent years wood strength researchers have begun to replace experimental unit allocation via random sampling with allocation via sorts based on nondestructive measurements of strength predictors such as modulus of elasticity and specific gravity. Although this procedure has the potential of greatly increasing experimental sensitivity, as currently implemented it can easily reduce sensitivity. In this paper we discuss the problem and we present solutions. Given the existence of nondestructive measurements of strength predictors, our methods can be used to reduce sample sizes. We have written a public domain computer program that implements the methods.
