Soil and Root Damage in Forestry

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

The purpose of this publication is to clarify further the tree decay concept that expands the classical concept to include the orderly response of the tree to wounding and infection--compartmentalization-- and the orderly infection of wounds by many microorganisms.

Forest soils form the foundation that underpins the existence of all forests. This book encapsulates soil ecology and functioning in northern forests, focusing on the effects of human activity and climate change. The authors introduce the fundamental principles necessary for studying forest soils, and explain the functioning and mutual influence of all parts of a forest soil ecosystem. A chapter is dedicated to each of soil acidity and heavy metal pollution, elevated carbon dioxide, nitrogen deposition and climate change, highlighting the most important anthropogenic factors influencing forest soil functioning and how these soils are likely to respond to environmental change. With its unique view of the functioning of the soils found under temperate and boreal forests in today's rapidly changing world, this book is of interest to anyone studying forestry and forest ecology in European, North American and North Asian contexts.

Provides direction on how to prepare operational plans and prescriptions that require specification of limits for various types of soil disturbance during forestry operations.

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.

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 southwestern ponderosa pine forests, wildfires have become unnaturally damaging because of decades of fire exclusion and the increased density of forest stands. Large, severe fires are well known to be destructive to forest vegetation and wildlife, but an additional, often-unseen effect of fires is on and in the ground the disruption of soil structure and properties that can have a cascade of effects throughout forest systems. Forest soils supply air, water, nutrients, and mechanical support for plants, and provide habitat for decomposers, nitrogen-fixing bacteria, and symbiotic fungi. Whether forest managers are looking to rehabilitate forests after wildfire or conduct restoration treatments intended to prevent severe wildfire, it is important to protect soils.

The Forest Regeneration Manual presents state-of-the-art information about current regeneration practices for southern pines in the United States. Over 1.2 billion seedlings of five major species -- loblolly, slash, longleaf, sand, and shortleaf -- are planted each year. In 22 chapters, the Manual details fundamental steps in establishing successful young pine plantations: regeneration planning, including economic and legal aspects; regeneration harvest methods; propagation by seed and vegetative techniques; bareroot and container seedling culturing in the nursery; measures of seedling quality; site potential; -- environment, associated vegetation, soils; matching species to sites; site preparation -- mechanical and chemical methods, fire, fertilization; seedling handling before planting; planting practices and measures of regeneration success; promoting early plantation growth and management of competing vegetation, insects, disease, and wildlife.

The purpose of this report is to review available information on soil compaction as related to soil and water conservation on forest and range lands.

Some no. include reports compiled from information furnished by State Foresters (and others).
