USDA Forest Service Experimental Forests and Ranges


Book Description

USDA Forest Service Experimental Forests and Ranges (EFRs) are scientific treasures, providing secure, protected research sites where complex and diverse ecological processes are studied over the long term. This book offers several examples of the dynamic interactions among questions of public concern or policy, EFR research, and natural resource management practices and policies. Often, trends observed – or expected -- in the early years of a research program are contradicted or confounded as the research record extends over decades. The EFRs are among the few areas in the US where such long-term research has been carried out by teams of scientists. Changes in society’s needs and values can also redirect research programs. Each chapter of this book reflects the interplay between the ecological results that emerge from a long-term research project and the social forces that influence questions asked and resources invested in ecological research. While these stories include summaries and syntheses of traditional research results, they offer a distinctly new perspective, a larger and more complete picture than that provided by a more typical 5-year study. They also provide examples of long-term research on EFRs that have provided answers for questions not even imagined at the time the study was installed.

Introduction to Forests and Renewable Resources


Book Description

For 75 years, few textbooks have served a topic as well as Introduction to Forests and Renewable Resources. Widely recognized for its comprehensive yet engaging coverage, this major revision provides an outstanding, up to date overview of management issues, conservation policies and practices related to forests and renewable resources, and an authoritative perspective on how these topics are evolving. New directions are covered, including: green certification of forest management and wood products; improved harvest practices in response to public concerns; carbon sequestration and ecological services as important forest yields; ecosystem restoration and resilience as management responds to concerns about global warming; and more. Well-illustrated with new examples, case studies and abundant photos, this eighth edition describes the importance and history of forests, evolution of policy, North American distribution of forests, and moves on to describe forest health strategies to combat insects, disease, damage from mammals, and fire. Ecological principles are explained as basis for forest management, with chapters on management of the associated resources of wildlife, watersheds and streams, range resources, outdoor recreation and wilderness. Market concerns and technology are embraced in chapters on economics, measurement and analysis, harvesting, and forest products. Concluding chapters describe management of forests and renewable resources by the federal government, by states, by private land owners, and in urban areas and communities. For forestry, natural resource, and environmental science students, involved citizens and resource users and professionals, this book is your reference and guide to forests and renewable resources.




Multiaged Silviculture


Book Description

This book presents the latest scientific and management information on multiaged silviculture, an emerging strategy for managing forestry systems worldwide. Over recent decades, forest science and management have tended to emphasize plantation silviculture. Whilst this clearly meets our wood production needs, many of the world's forests need to be managed far less intensively and more flexibly in order to maintain their natural ecosystem functions together with the values inherent in those processes. Developing multiaged management strategies for these complex forest ecosystems represents a global challenge to successfully integrate available science with sustainable management practices. Multiaged Silviculture covers the ecology and dynamics of multiaged stands, the management operations associated with regeneration, tending, and stocking control, and the implications of this strategy on production, genetic diversity, and stand health. It is primarily aimed at graduate level students and researchers in the fields of forestry and silviculture, but will also be of relevance and use to all professional foresters and silviculturists.




Taking Stock


Book Description

What is American government like today? How has it changed--and how has it remained the same--over the course of the century now coming to a close? Taking Stock seeks to provide the fullest and most thoughtful answers yet offered to these questions. It brings together eminent historians and political scientists to examine the past experience, current state, and future prospects of five major American public issues: trade and tariff policy, immigration and aliens, conservation and environmentalism, civil rights, and social welfare.




America's Renewable Resources


Book Description

By recording one country's experience with its vast natural resource base, America's Renewable Resources: Historical Trends and Current Challenges will help to inform the management of future demands on the resource base in the U.S. and throughout the world. The contributors focus specifically on renewable resources--water, forests, rangeland, cropland and soils, and wildlife--which possess the capacity to restore themselves after they have be consumed. Because this capacity can be destroyed and the time required for restoration can be very long, a balance in their use is necessary to sustain continued productivity. In arresting fashion, the authors trace the history of each resource's use from early colonial times through periods of dramatic, sometimes cataclysmic, changes in its utilization by an expanding, diversifying society. They show how unforeseen consequences have forced social institutions into existence and compelled policy makers, especially at the federal level, to deal with problems for which they were largely unprepared. America's Renewable Resources, by examining changes in demand, technologies, policies, and institutions, will assist both policy makers and the public at large to look past short-term events to the conditions fundamental to maintaining our future economic and environmental wellbeing.
