Agroforestry has significantly impacted our forests, but an often-overlooked issue is the effect of harvesting on soils and root systems. Soil and Root Damage in Forestry explains how soil and roots might be damaged through logging activities or silvicultural activities, how resulting root diseases impact the root and soil systems, and the impacts of chemical applications on the soil and root system. This book goes beyond the ‘why’ to also provide methods to reduce the impacts of machines on soils and offers solutions to minimize the impacts of machines on soils. Soil and Root Damage in Forestry serves as a valuable resource not only for those already working in soil science and forest ecology, but also provides insights for advanced students seeking an entrance to the "hidden half" of the planet. Combines damages to soil and roots in one volume for the first time Includes calculations related to soil strength providing soil scientists and ecologists with methods to estimate root damage Provides suggestions on how to reduce the impact of harvesting on soil and root systems

T. C. Hutchinson The NATO Advanced Research Workshop detailed in this volume was held in Toronto, Canada, in 1985. The purpose of the Workshop was to provide a "state of the art" report on our knowledge of the sensitivities and responses of forests, wetlands and crops to airborne pollutants. Approximately 40 scientific experts from nine countries participated. Most participants were actively involved in research concerning the effects of air pollutants on natural or agro-ecosystems. These pollutants included acidic deposition, heavy metal particulates, sulphur dioxide, ozone, nitrogen oxides, acid fogs and mixtures of these. Also invited were experts on various types of ecosystem stresses, physiologi cal mechanisms pertinent to acid deposition, and other areas that were felt by the director to be of direct relevance, including: effects of ethylene on vegetation, the physiology of drought in trees, the nature and role of plant cuticles as barriers to acid rain penetration, the use of dendrochronological techniques in reconstructing the time of onset and the subsequent progression of growth declines, the ability of soils to naturally generate acidity, the role of Sphagnum moss in natural peat land acidity, the use of lichens as indicators of changing air quality, and the magnitude of natural emissions of reduced sulphur gases from tropical rainforests and temperate deciduous forests. The Workshop included a series of invited presentations and subsequent group discussions. These presentations were designed to allow syntheses of our present knowledge as well as detailed questioning and discussion.

The objective of this book is to outline the serious dangers to the soil and forest as a result of continuing emissions of acid-producing gases, thus pointing to the urgent need of their reduction. This volume reviews relevant information dealing with changes due to acidification of the soil and with the physiological processes of the tree involved in nutrient uptake, transfer, and utilization as well as with the nature and degree of damage that has occurred. Written in a comprehensive format, it discusses the importance of viable forests, the vital role of nutrients in the structure and physiology of the tree, and the relevance of prior dieback episodes. This is a valuable resource for those interested in forestry, environmental science, and the pulp and paper industry.

The future of the world's forests is at the forefront of environmental debate. Rising concerns over the effects of deforestation and climate change are highlighting the need both to conserve and manage existing forests and woodland through sustainable forestry practices. The Forests Handbook, written by an international team of both scientists and practitioners, presents an integrated approach to forests and forestry, applying our present understanding of forest science to management practices, as a basis for achieving sustainability. Volume One presents an overview of the world's forests; their locations and what they are like, the science of how they operate as complex ecosystems and how they interact with their environment. Volume Two applies this science to reality; it focuses on forestry interventions and their impact, the principles governing how to protect forests and on how we can better harness the enormous benefits forests offer. Case studies are drawn from several different countries and are used to illustrate the key points. Development specialists, forest managers and those involved with land and land-use will find this handbook a valuable and comprehensive overview of forest science and forestry practice. Researchers and students of forestry, biology, ecology and geography will find it equally accessible and useful.

Effects of Accumulation of Air Pollutants in Forest Ecosystems

This volume is based on a workshop on "Effects of accumulation of air pollutants in forest ecosystems'; held in GOttingen, Federal Republic of Germany, from May 16-18, 1982. This work'shop was initiated and sponsored by the Environmental Agency of the Federal Republic of Germany (project officer: Dr. J. Pankrath) as part of a research contract (project leader: Dr. B. Ulrich). THE PROBLEM SEEN UNDER THE ASPECT OF ADMINISTRATION The problem of forest damage caused by air pollution is not new in Europe. Already in 1983 a comprehensive report from Schroeder and Reuss about vegetation damages by fume in the Harz mountains was published. In 1923, Prof. Dr. Julius Stocklasa of the Bohemian Technical Highschool in Prague was concerned with research of toxical effects of sulphur dioxide in his publication "The damage of vegetation by flue gas and exhalations of facili ties". This comprehensive and instructive work concludes with the sentence: "It is already high time for the governments of all cultural states to take legal, police and private measures in order to prevent damage by flue gases". In the neighbourhood of industries with high gaseous and dust emissions damages have been shown to occur for a long timei these deleterious effects have influenced the growth of trees and in extreme cases have even caused their early death.

In the past decade, there has been much debate over the environmental impact of forestry. People are justifiably concerned about what is happening to the local and global forest environments, but they are also confused by the polarized rhetoric that has characterized both sides of the debate. In Balancing Act, Hamish Kimmins calls for a balanced, more objective approach to forestry issues in order to bridge the gap between the most extreme opponents in the debate. He suggests that we need to begin with a common understanding of what forestry is about and how forest ecosystems work. He outlines the scientific and ecological aspects of the major environmental issues facing British Columbia and the world today, arguing that we need to disentangle the scientific from the value-based social aspects of these questions. He also contends that much of the current debate about forests and their management ignores the time dimension of ecosystems, and he calls for a more dynamic view of current environmental issues in forestry -- one that accounts for change. The first few chapters provide an outline of the basic principles of forestry and ecology, and subsequent chapters discuss the major environmental issues facing forestry in the 1990s. These include clearcutting, slashburning, management chemicals, old growth, biological diversity, 'new forestry, ' climate change, acid rain, the comparison between temperate and tropical forestry, and long-term decisions in forestry. Balancing Act is essential reading for those who are searching for an objective, accurate, and readable evaluation of the issues at the heart of the forestry/environment debate. By emphasizing that forests are not static but change over time, Kimmins adds an important, often ignored, dimension to the discussion. Only by understanding all the intricacies of the ecosystems can we learn to manage our forests in a sustainable fashion.
