Salvage logging—removing trees from a forested area in the wake of a catastrophic event such as a wildfire or hurricane—is highly controversial. Policymakers and those with an economic interest in harvesting trees typically argue that damaged areas should be logged so as to avoid “wasting” resources, while many forest ecologists contend that removing trees following a disturbance is harmful to a variety of forest species and can interfere with the natural process of ecosystem recovery. Salvage Logging and Its Ecological Consequences brings together three leading experts on forest ecology to explore a wide range of issues surrounding the practice of salvage logging. They gather and synthesize the latest research and information about its economic and ecological costs and benefits, and consider the impacts of salvage logging on ecosystem processes and biodiversity. The book examines • what salvage logging is and why it is controversial • natural and human disturbance regimes in forested ecosystems • differences between salvage harvesting and traditional timber harvesting • scientifically documented ecological impacts of salvage operations • the importance of land management objectives in determining appropriate post-disturbance interventions Brief case studies from around the world highlight a variety of projects, including operations that have followed wildfires, storms, volcanic eruptions, and insect infestations. In the final chapter, the authors discuss policy management implications and offer prescriptions for mitigating the impacts of future salvage harvesting efforts. Salvage Logging and Its Ecological Consequences is a “must-read” volume for policymakers, students, academics, practitioners, and professionals involved in all aspects of forest management, natural resource planning, and forest conservation.

Breiter Überblick zum Stand des Wissens Ökosysteme werden durch Wind, Feuer, Insekten- oder Pilzbefall sowie durch die anthropogene Landnutzung gestört. Störungen können Ökosysteme rasch wandeln, aber langfristig auch zu deren Stabilisierung beitragen. In der Summe aller in einer Landschaft wirkenden Störungen ergibt sich ein Störungsregime, welches durch typische Rhythmen und Interaktionen gekennzeichnet ist. Das vorliegende Lehrbuch ist das erste in deutscher Sprache zu dieser Thematik. In 18 Kapiteln charakterisiert es Störungstypen und Störungsregime sowie ihre Bedeutung für Ökosysteme und beschreibt die Anpassungen von Arten und Pflanzengemeinschaften an diese Störungen. Es bietet einen breiten Überblick zum Stand des Wissens in der Störungsökologie. Zahlreiche Beispiele illustrieren dabei die Verhältnisse in Mitteleuropa.

The Ecological Importance of Mixed Severity Fires

Genre: Science

The Ecological Importance of High-Severity Fires, presents information on the current paradigm shift in the way people think about wildfire and ecosystems. While much of the current forest management in fire-adapted ecosystems, especially forests, is focused on fire prevention and suppression, little has been reported on the ecological role of fire, and nothing has been presented on the importance of high-severity fire with regards to the maintenance of native biodiversity and fire-dependent ecosystems and species. This text fills that void, providing a comprehensive reference for documenting and synthesizing fire's ecological role. Offers the first reference written on mixed- and high-severity fires and their relevance for biodiversity Contains a broad synthesis of the ecology of mixed- and high-severity fires covering such topics as vegetation, birds, mammals, insects, aquatics, and management actions Explores the conservation vs. public controversy issues around megafires in a rapidly warming world

Effects of Timber Harvest Following Wildfire in Western North America

Author: David L. Peterson
Publisher: DIANE Publishing
ISBN: 9781437926668
Release Date: 2010-11

Timber harvest following wildfire leads to different outcomes depending on the biophysical setting of the forest, pattern of burn severity, operational aspects of tree removal, and other activities. Postfire logging adds to these effects by removing standing dead trees (snags) and disturbing the soil. The influence of postfire logging depends on the intensity of the fire, intensity of the logging operation, and mgmt. activities such as fuel treatments. Removal of snags reduces long-term fuel loads but generally results in increased amounts of fine fuels for the first few years after logging. Cavity-nesting birds, small mammals, and amphibians may be affected by harvest of standing dead and live trees, with negative effects on most species. Illustrations.

This synthesis provides an ecological foundation for management of the diverse ecosystems and fire regimes of North America, based on scientific principles of fire interactions with vegetation, fuels, and biophysical processes. Although a large amount of scientific data on fire exists, most of those data have been collected at small spatial and temporal scales. Thus, it is challenging to develop consistent science-based plans for large spatial and temporal scales where most fire management and planning occur. Understanding the regional geographic context of fire regimes is critical for developing appropriate and sustainable management strategies and policy. The degree to which human intervention has modified fire frequency, intensity, and severity varies greatly among different ecosystems, and must be considered when planning to alter fuel loads or implement restorative treatments. Detailed discussion of six ecosystems--ponderosa pine forest (western North America), chaparral (California), boreal forest (Alaska and Canada), Great Basin sagebrush (intermountain West), pine and pine-hardwood forests (Southern Appalachian Mountains), and longleaf pine (Southeastern United States)--illustrates the complexity of fire regimes and that fire management requires a clear regional focus that recognizes where conflicts might exist between fire hazard reduction and resource needs. In some systems, such as ponderosa pine, treatments are usually compatible with both fuel reduction and resource needs, whereas in others, such as chaparral, the potential exists for conflicts that need to be closely evaluated. Managing fire regimes in a changing climate and social environment requires a strong scientific basis for developing fire management and policy.

Criteria and Indicators for Sustainable Woodfuels

Release Date: 2010
Genre: Technology & Engineering

With growing pressure on energy resources and a heavy dependence on non-renewable fossil fuels, the world faces two key energy-related problems: the lack of a secure and affordable supply, and the threat of overconsumption leading to irreversible environmental damage. As part of the solution to these problems, many countries are looking increasingly to their biomass-energy resources. This publication focuses on one major source of biomass energy -- woodfuels. It sets out principles, criteria and indicators to guide the sustainable use of woodfuel resources and the sustainable production of charcoal. It is designed to help policy- and decision-makers in forestry, energy and environment agencies, non-governmental and other civil-society organizations and the private sector ensure that the woodfuel sector reaches its full potential as an agent of sustainable development."--back cover

Forests in Time

Genre: History

The Eastern Hemlock, massive and majestic, has played a unique role in structuring northeastern forest environments, from Nova Scotia to Wisconsin and through the Appalachian Mountains to North Carolina, Tennessee, and Alabama. A "foundation species" influencing all the species in the ecosystem surrounding it, this iconic North American tree has long inspired poets and artists as well as naturalists and scientists. Five thousand years ago, the hemlock collapsed as a result of abrupt global climate change. Now this iconic tree faces extinction once again because of an invasive insect, the hemlock woolly adelgid. Drawing from a century of studies at Harvard University's Harvard Forest, one of the most well-regarded long-term ecological research programs in North America, the authors explore what hemlock's modern decline can tell us about the challenges facing nature and society in an era of habitat changes and fragmentation, as well as global change.

Publisher: University of Arizona Press
ISBN: 0816527385
Release Date: 2008
Genre: History

Roughly centered on the Four Corners region of the southwestern United States, the Colorado Plateau covers an area of 130,000 square miles. The relatively high semi-arid province boasts nine national parks, sixteen national monuments, many state parks, and dozens of wilderness areas. With the highest concentration of parklands in North America and unique geological and ecological features, the area is of particular interest to researchers. Derived from the Eighth Biennial Conference of Research on the Colorado Plateau, this third volume in a series of research on the Colorado Plateau expands upon the previous two books. This volume focuses on the integration of science into resource management issues, summarizes what criteria make a successful collaborative effort, outlines land management concerns about drought, provides summaries of current biological, sociological, and archaeological research, and highlights current environmental issues in the Four Corner States of Arizona, New Mexico, Colorado, and Utah. With broad coverage that touches on topics as diverse as historical aspects of pronghorn antelope movement patterns through calculating watershed prescriptions to the role of wind-blown sand in preserving archaeological sites on the Colorado River, this volume stands as a compendium of cuttingedge management-oriented research on the Colorado Plateau. The book also introduces, for the first time, tools that can be used to assist with collaboration efforts among landowners and managers who wish to work together toward preserving resources on the Colorado Plateau and offers a wealth of insights into land management questions for many readers, especially people interested in the natural history, biology, anthropology, wildlife, and cultural management issues of the region.

The Economics of Salvage Harvesting and Reforestation in British Columbia s Mountain Pine Beetle affected Forests

Author: Brian Peter
ISBN: MINN:31951D031016572
Release Date: 2010
Genre: Forest management

In stands with significant mountain pine beetle (MPB) mortality, forest managers face a range of choices including clearcut harvesting, partial cutting, various rehabilitation strategies, and non-intervention. These choices involve many long-term costs, benefits, and risks, some of which can be assessed through economic analysis. After reviewing the context for this issue, the authors provided case studies that span the more likely stand-level problems faced by decision makers. All analyses were conducted from the perspective of the landowner (i.e., government) rather than the user of the resource (i.e., licensee). The insights from the case studies form a basis to answer the following core questions: Are some stand types better left unsalvaged? What economic/silvicultural assumptions produce higher stand values when salvaging is foregone? In areas that cannot be salvaged, is reforestation a profitable investment? Finally, does partial cutting make sense economically?--Document.
