Book Description
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.

Book Description
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.

Book Description
Forest Management and Planning, Second Edition, addresses contemporary forest management planning issues, providing a concise, focused resource for those in forest management. The book is intermixed with chapters that concentrate on quantitative subjects, such as economics and linear programming, and qualitative chapters that provide discussions of important aspects of natural resource management, such as sustainability. Expanded coverage includes a case study of a closed canopy, uneven-aged forest, new forest plans from South America and Oceania, and a new chapter on scenario planning and climate change adaptation. Helps students and early career forest managers understand the problems facing professionals in the field today Designed to support land managers as they make complex decisions on the ecological, economic, and social impacts of forest and natural resources Presents updated, real-life examples that are illustrated both mathematically and graphically Includes a new chapter on scenario planning and climate change adaptation Incorporates the newest research and forest certification standards Offers access to a companion website with updated solutions, geographic databases, and illustrations

Book Description
The capacity of mixed forests to mitigate climate change effects by increasing resilience and lowering risks is pinpointed as an opportunity to highlight the role of tree species rich forests as part of complex socio-ecological systems. This book updates and presents the state-of-the-art of mixed forest performance in terms of regeneration, growth, yield and delivery of ecosystem services. Examples from more than 20 countries in Europe, North Africa and South America provide insights on the interplay between structure and functionining, stability, silviculture and optimization of management of this type of forests. The book also analyses the role of natural mixed forests and mixed plantations in the delivery of ecosystem services and the best modelling strategy to study mixed forest dynamics. The book is intended to serve as a reference tool for students, researchers and professionals concerned about the management of mixed forests in a context of social and environmental change.

Book Description
Forest Plans of North America presents case studies of contemporary forest management plans developed for forests owned by federal, state, county, and municipal governments, communities, families, individuals, industry, investment organizations, conservation organizations, and others in the United States, Canada, and Mexico. The book provides excellent real-life examples of contemporary forest planning processes, the various methods used, and the diversity of objectives and constraints faced by forest owners. Chapters are written by those who have developed the plans, with each contribution following a unified format and allowing a common, clear presentation of the material, along with consistent treatment of various aspects of the plans. This work complements other books published by members of the same editorial team (Forest Management and Planning, Introduction to Forestry and Natural Resource Management), which describe the planning process and the various methods one might use to develop a plan, but in general do not, as this work does, illustrate what has specifically been developed by landowners and land managers. This is an in-depth compilation of case studies on the development of forest management plans by the different landowner groups in North America. The book offers students, practitioners, policy makers, and the general public an opportunity to greatly improve their appreciation of forest management and, more importantly, foster an understanding of why our forests today are what they are and what forces and tools may shape their tomorrow. Forest Plans of North America provides a solid supplement to those texts that are used as learning tools for forest management courses. In addition, the work functions as a reference for the types of processes used and issues addressed in the early 21st century for managing land resources. Presents 40-50 case studies of forest plans developed for a wide variety of organizations, groups, and landowners in North America Illustrates plans that have specifically been developed by landowners and land managers Features engaging, clearly written content that is accessible rather than highly technical, while demonstrating the issues and methods involved in the development of the plans Each chapter contains color photographs, maps, and figures

Book Description
"This is a forest measurements textbook written for field technicians. Silvicultural applications and illustrations are provided to demonstrate the relevance of the measurements. Special “technique tips” for each skill are intended to help increase data collection accuracy and confidence. These include how to avoid common pitfalls, effective short cuts, and essentials for recording field data correctly. The emphasis is on elementary skills; it is not intended to be a timber cruising guide"--BC Campus website.

Book Description
Six stands of Eucalyptus regnans and E. delegatensis with significantly contagious or clumped spatial patterns, were observed between either ages 4 and 12 or ages 30 and 41 years. The effects of aggregation on the development of these stands are described. The prediction of growth and mortality responses of individual trees is demonstrated in these stands where average stand density measures are not good indicators of the competitive conditions which individual trees face. Results show that clumping intensifies competition, producing a high proportion of suppressed stems and substantial mortality even in regions of low average density. Average tree size is reduced. The bimodal diameter distribution illustrates the distinct separation of the suppressed class from the dominants and codominants. Individual tree growth differs significantly between crown classes. Basal area growth of the suppressed stems which survive averages near zero. In all crown classes variables which reflect competitive conditions such as distance to the nearest neighbouring tree and the basal area in larger trees are more successful predictors of individual tree growth than average stand density variables. Mortality is largely confined to the suppressed class and within any stand can be predicted by tree size and local density variables. The concentration of mortality in the densest parts of the stands is changing the spatial pattern, so that the degree of contagion is decreasing through time. A high degree of contagion results in increased variability of conditions within a stand and high local densities around some trees. The associated intensification in competition in these areas of the stand produces responses which are similar to those we would expect under an increase in general density.
