Drawing upon a wealth of past research and results, this book provides a comprehensive summary of state-of-the-art methods for empirical modeling of forest trees and stands. It opens by describing methods for quantifying individual trees, progresses to a thorough coverage of whole-stand, size-class and individual-tree approaches for modeling forest stand dynamics, growth and yield, moves on to methods for incorporating response to silvicultural treatments and wood quality characteristics in forest growth and yield models, and concludes with a discussion on evaluating and implementing growth and yield models. Ideal for use in graduate-level forestry courses, this book also provides ready access to a plethora of reference material for researchers working in growth and yield modeling.

The aim of this book is to improve the understanding of forest dynamics and the sustainable management of forest ecosystems. How do tree crowns, trees or entire forest stands respond to thinning in the long term? What effect do tree species mixtures and multi-layering have on the productivity and stability of trees, stands or forest enterprises? How do tree and stand growth respond to stress factors such as climate change or air pollution? Furthermore, in the event that one has acquired knowledge about the effects of thinning, mixture and stress, how can one make that knowledge applicable to decision-making in forestry practice? The experimental designs, analytical methods, general relationships and models for answering questions of this kind are the focus of this book. Given the structures dealt with, which range from plant organs to the tree, stand and enterprise levels, and the processes analysed in a time frame of days or months to decades or even centuries, this book is directed at all readers interested in trees, forest stands and forest ecosystems. This work has been compiled for students, scientists, lecturers, forest planners, forest managers, and consultants.
Forest Growth and Yield Modeling synthesizes current scientific literature and provides insights in how models are constructed. Giving suggestions for future developments, and outlining keys for successful implementation of models the book provides a thorough and up-to-date, single source reference for students, researchers and practitioners requiring a current digest of research and methods in the field. The book describes current modelling approaches for predicting forest growth and yield and explores the components that comprise the various modelling approaches. It provides the reader with the tools for evaluating and calibrating growth and yield models and outlines the steps necessary for developing a forest growth and yield model. Single source reference providing an evaluation and synthesis of current scientific literature Detailed descriptions of example models Covers statistical techniques used in forest model construction Accessible, reader-friendly style
Comprehensive book describes the various growth patterns of forests. The purpose is to help silviculturalists and forest managers understand and anticipate how forests grow and respond to intentional manipulations and natural disasters.
Trees and forests are large and complex, but even something as difficult as the amount of wood they contain can be measured with quite unsophisticated equipment. Everyone, from professional foresters to the layperson, who works with forests and needs to measure them no matter where in the world, will appreciate this book. It summarises modern forest measurement techniques and describes why forests are measured, how to measure them, and the basis of the science behind these techniques. Professor Phil West has been a forest scientist for over 30 years. His research speciality is the mathematical modelling of forest growth behaviour. He is presently a forestry consultant and teaches forest measurement in the forestry school of Southern Cross University in northern New South Wales, Australia.
Timber measurement techniques applicable to any tree inventory project regardless of management objectives are covered by this text. Thorough coverage of sampling designs, land measurements, tree measurements, forest inventory field methods, and growth projections ensures utility for all foresters. Included are chapters on aerial photographs, GIS, and using similar techniques to measure other natural resources such as rangelands, wildlife, and water.
Van Laar and Akça’s popular text book, Forest Mensuration, was first published in 1997. Like that first edition, this modern update is based on extensive research, teaching and practical experience in both Europe, and the tropics and subtropics. However, it has also been extensively revised, and now includes chapters on remote sensing and the application of aerial photographs and satellite imagery. The book assumes no advanced knowledge of statistical methods, and combines practical techniques with important historical and disciplinary context. The result is a strong balance between a handbook and a valuable reference.
Forestry cannot be isolated from the forces that drive all economic activity. It involves using land, labour, and capital to produce goods and services from forests, while economics helps in understanding how this can be done in ways that will best meet the needs of people. Therefore, a firm grounding in economics is integral to sound forestry policies and practices. This book, a major revision and expansion of Peter H. Pearse’s 1990 classic, provides this grounding. Updated and enhanced with advanced empirical presentation of materials, it covers the basic economic principles and concepts and their application to modern forest management and policy issues. Forest Economics draws on the strengths of two of the field’s leading practitioners who have more than fifty years of combined experience in teaching forest economics in the United States and Canada. Its comprehensive and systematic analysis of forest issues makes it an indispensable resource for students and practitioners of forest management, natural resource conservation, and environmental studies.
