Book excerpt: Today environmental problems of unprecedented magnitude confront planet earth. The sobering fact is that a whole range of human activities is affecting our global environment as profoundly as the billions of years of evolution that preceded our tenure on Earth. The pressure on vital natural resources in the developing world and elsewhere is intense, and the destruction of tropical forests, wildlife habitat, and other irreplaceable resources, is alarming. Climate change, ozone depletion, loss of genetic diversity, and marine pollution are critical global environmental concerns. Their cumulative impact threatens to destroy the planet's natural resources. The need to address this situation is urgent. More than at any previous moment in history, nature and ecological systems are in human hands, dependent on human efforts. The earth is an interconnected and interdependent global ecosystem, and change in one part of the system often causes unexpected change in other parts. Atmospheric, oceanic, wetland, terrestrial and other ecological systems have a finite capacity to absorb the environmental degradation caused by human behavior. The need for an environmentally sound, sustainable economy to ease this degradation is evident and urgent. Policies designed to stimulate economic development by foregoing pollution controls both destroy the long-term economy and ravage the environment. Over the years, we have sometimes drawn artificial distinctions between the health of individuals and the health of ecosystems. But in the real world, those distinctions do not exist.

Book excerpt: The Forest Inventory and Analysis (FIA) Program of the Forest Service, U.S. Department of Agriculture, conducts a national inventory of forests across the United States. A systematic subset of permanent inventory plots in 38 States is currently sampled every year for numerous forest health indicators. One of these indicators, crown-condition classification, is designed to estimate tree crown dimensions and assess the impact of crown stressors. The indicator features eight tree-level field measurements in addition to variables traditionally measured in conjunction with FIA inventories: vigor class, uncompacted live crown ratio, crown light exposure, crown position, crown density, crown dieback, foliage transparency, and crown diameter. Indicators of crown health derived from the crown data are intended for analyses at the State, regional, and national levels, and contribute to the core tabular output in standard FIA reports. Crown-condition measurements were originally implemented as part of the Forest Health Monitoring (FHM) Program in 1990. Except for crown diameter, these measurements were continued when the FIA Program assumed responsibility for FHM plot-based detection monitoring in 2000. This report describes in detail the data collection and analytical techniques recommended for crown-condition classification.

Download or read book Air Pollution and Forests written by William H. Smith and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 614 pages. Available in PDF, EPUB and Kindle. Book excerpt: This series is dedicated to serving the growing community of scholars and practitioners concerned with the principles and applications of environmental management. Each volume will be a thorough treatment of a specific topic of importance for proper management practices. A fundamental objective of these books is to help the reader discern and implement human's stewardship of our environment and the world's renewable resources. For we must strive to understand the relationship between humankind and nature, act to bring harmony to it, and nurture an environment that is both stable and productive. These objectives have often eluded us because the pursuit of other individual and societal goals has diverted us from a course of living in balance with the environment. At times, therefore, the environmental manager may have to exert restrictive control, which is usually best applied to humans, not nature. Attempts to alter or harness nature have often failed or backfired, as exemplified by the results of imprudent use of herbicides, fertilizers, water, and other agents. Each book in this series will shed light on the fundamental and applied aspects of environmental management. It is hoped that each will help solve a practical and serious environmental problem.

This book was released on 2012-12-06 with total page 499 pages. Available in PDF, EPUB and Kindle. Book excerpt: The proceedings of a special technical session dealing with the addition of Ca based materials to waters and soils for the purpose of restoring or enhancing fisheries in acidified waters are contained in this volume. The session was part of the North American Fisheries Society's annual meeting sponsored by the Water Quality Section of the Society. While the concept of liming is not new, the extent of the recent research, demonstrations and applications reported at the conference is enlightening. Six countries are represented by government, state and private sector participants. The scope of activities reported in the following 23 papers range from the simple to the very complex addition of liming materials to ponds, lakes, streams and watersheds. This volume of presentations is broad and impressive as are the methods used in the actual application of the neutralizing materials. Those programs that are demonstration application oriented are deploying techniques that are either new or modifications of existing technology.

Available in PDF, EPUB and Kindle. Book excerpt: This book assesses the current state of knowledge about forest declines, particularly as they relate to air pollution. Many declines are shown to be unrelated to air pollution and, in other cases, the links between air pollution and the condition of the trees is extremely tenuous. Factors such as nutrient depletion due to past management practices and drought are shown to have had a major influence on the health of trees. In many cases, the evidence for a decline in tree condition is at best ambiguous, and much of the concern appears to have been generated by political and media interest rather than by a critical evaluation of the available data. A detailed examination of the comprehensive data collected in the British forest health monitoring program over the last five years indicates the complexity of the process involved and illustrates the dangers of taking data from a single year at face value. Many of the indices used to assess trees are of questionable value when compared over time or space, as their subjective nature precludes any reliable comparisons. Studies of annual increment and wood quality indicate that the international market for timber is unlikely to be affected in either the long or the short term.

Available in PDF, EPUB and Kindle. Book excerpt: Remote sensing was the primary data source since the launch of the first environmental monitoring satellite back in 1972. In the past five decades, remote sensing technology has come a long way and evolved into a mature science. Even so, new technologies, new theories, new methodologies, and new applications continue to emerge. With the rapid pace of technological advancement, it is essential to share experiences especially between different disciplines, either on breakthroughs in new theory or understanding, or applications of remote sensing on real world issues. Disciplines or fields covered in this book include geography, geology, agriculture, forestry, botany, and oceanography. Though remote sensing may be used differently in various disciplines, the principles are similar, if not the same. This book will be valuable to scientists, scholars, working professionals, or students who use remote sensing in their work, and are interested in learning how others use remote sensing in different ways.
