"In a Dark Wood" presents a history of debates among ecologists over what constitutes good forestry, and a critique of the ecological reasoning behind contemporary strategies of preservation, including the Endangered Species Act. Chase argues that these strategies, in many instances adopted for political, rather than scientific reasons, fail to promote biological diversity and may actually harm more creatures than they help. At the same time, Chase offers examples of conservation strategies that work, but which are deemed politically incorrect and ignored. In a Dark Wood provides the most thoughtful and complete account yet written of radical environmentalism. And it challenges the fundamental--but largely unexamined--assumptions of preservationism, such as those concerning whether there is a "balance of nature," whether all branches of ecology are really science, and whether ecosystems exist. In his new introduction, Chase evaluates the response to his book and reports on recent developments in environmental science, policy, and politics. In a Dark Wood was judged by a recent national poll to be one of the one hundred best nonfiction books written in the English language during the twentieth century. A smashing good read, this book will be of interest to environmentalists, ecologists, philosophers, biologists, and bio-ethicists, and anyone concerned about ecological issues.
As a natural science, silviculture has a large say in how humans interact with the terrestrial world. Although the perspective taken here that the production of wood is narrow, the amount of land area consumed is extensive; the indirect consequences of wood production on natural processes are larger still. Through the amount of land engaged, the flora and fauna affected and the environmental consequences, good or bad; silviculture is a frequent constituent in applied ecology, environmental science, conservation ecology and other broad land-use disciplines. Silvicultural expertize is essential when trees and wood are an economic output; often best promoted when silviculture is allied with hydrology, ecology, soil science, wildlife management, etc. This book touches upon the following important areas of the subject in detail.
From recycled products to organic food, the movement to be "environmentally friendly" is now expanding into the forestry field. Recognizing this impact, Home Depot has committed to giving preference to selling "certified wood," proven to come from forests that meet certain biological and social sustainablility standards. Retailers and vendors can offer certified wood through the international Forest Stewardship Council (FSC) and FSC accredited organizations like SmartWood, recently featured in People magazine.
In this manual, Post-harvest Tobacco Infestation Control, we have addressed the 'state-of-the-art' and given little account of obsolete techniques. With contributing authors from international cigarette manufacturers, plus consultation with the worldwide tobacco industry, we have recorded the acceptable methodology for infestation management. This manual fills a void, as the most recent treatment of this subject was more than 20 years 350 ago. Major emphasis is on sanitation which should, where possible, reduce or replace pesticide use at all stages of tobacco processing. This manual is divided into an introduction and chapters dealing with: biology, monitoring, sanitation, physical control and insecticides - with separate chapters on insect growth regulators and fumigation. At the end, a few case histories are outlined to show how this integrated approach to infestation control is put into practice. Comments from users of this manual regarding general usefulness, omissions and/or corrections are welcome and should be addressed to CORESTA, the infestation control subgroup of the Phytopathology group. Introduction 1 Tobacco is vulnerable to many insect pests while growing in the 13 357 field. 4. 3 * Farmers may use pesticides to help control some insects and avoid losing up to 40% of the growing crop. Two insects, the cigarette beetle (Lasioderma serricorne) and the tobacco moth (Ephestia elutella), feed on cured tobacco leaves, whether air-cured burley, sun-cured oriental, flue-cured or tobacco by-products (Chapter 2).

This collection features four peer-reviewed reviews on restoring degraded forests. The first chapter reviews the restoration of tropical forests, focusing specifically on forest landscape restoration (FLR). It addresses the importance of implementing FLR and provides two detailed case studies to demonstrate this. The chapter concludes with a discussion on the challenges and opportunities in taking FLR forwards. The second chapter considers the importance of exploiting the genetics of tropical tree species for the restoration of tropical forests. The chapter identifies and reviews the available methods to measure genetic diversity and suitability for future plantation establishment, including field trials and molecular markers. The third chapter provides an overview of ecosystem services delivered by tropical agroforestry systems (AFS). The chapter reviews practical approaches for trade-off analysis between ecosystem services and plant biodiversity for better design (or redesign), as well as the sustainable management of AFS. The final chapter discusses how measuring, monitoring and managing the environmental impact of plantation operations are key components in sustainable palm oil production. The chapter examines the operational impacts of oil palm cultivation on biodiversity, as well as how oil palm production can be balanced to ensure forest conservation.
Forestry today, like many other sectors that traditionally rely on material goods, faces significant global drivers of societal change that are less often addressed than the environmental concerns commonly in the spotlight of scientific, political, and news media. There are three major interconnected issues that are challenging forestry at its foundation: urbanization, tertiarization, and globalization. These issues are at the core of this book. The urbanization of society, a process in development from the first steps of industrialization, is particularly significant today with the predominance and quick growth rate of the world's urban population. Ongoing urbanization is creating new perspectives on forestry, inducing changes in its social representation, and changing lifestyles and practices with a tendency toward dematerialization. The process of urbanization is also creating a disconnect and in some ways is leaving behind rurality, the sector of society where forestry has traditionally developed and taken place over centuries. The second issue covered in this book is the tertiarization of the economy. In society today, the sector of services largely dominates the economy and occupies the major part of the world's active population. This ongoing process modifies professional modalities and ways of life and opens new doors to forests through the immaterial goods they provide. It also profoundly changes the framework, rules, processes, means of production, exchanges between economic factors, and the processes of innovation. The third issue is undoubtedly globalization in its economic, political, and social components. Whether it's through bridging distances, crossing borders, accelerating changes, standardizing practices, leveling hierarchical structures, or pushing for interdependence, globalization impacts everyone, everywhere in multiple ways. Forestry is no exception. Forestry in the Midst of Global Changes focuses on these global drivers of change from the perspective of their relationships with how society functions. By analyzing them in depth through multidisciplinary, interdisciplinary, and even transdisciplinary approaches, this book is helping to design the forestry of tomorrow.
America's 754 million acres of forest constitute more than a major geographical feature. They are intricately woven into the national economy and culture-providing a fifth of the nation's industrial raw material, protecting and regulating its watersheds, providing grazing range for a sizeable portion of livestock, producing most of its game and much of its nonsport wildlife, and attracting millions of tourists annually.
During the Green Revolution in many developing countries, agroforestry systems tended to reflect modern agricultural systems by their intensive use of fertilizers, pesticides, and site modifications to fit the desired crop. Since the 1980's, agroforestry has learned from traditional indigenous systems to work more closely with the fertility of marginal lands through the use of less intensive cultivation and fallow periods.
First published in 1995, The Forest Certification Handbook has become the landmark book concerning all aspects of forest and wood product certification from policy to business to in-the-field technical issues. Yet since first publication an enormous amount has happened in the field. This new second edition has been entirely rewritten to incorporate the changes over the past decade, and is a complete and up-to-date source of information on all aspects of developing, selecting and operating a forest certification programme that provides both market security and raises standards of forest management.
There has been a recent resurgence of interest in wood energy as part of a sustainable range of renewable energy options. This book addresses the current gap in the energy and public policy literature for a reference book that compiles the most-recent wood energy assessments, and evaluates current and potential future wood energy uses and the role for public policy to foster efficient use of the most-widely consumed renewable energy in the world. It brings together a group of expert authors covering topics from forest management, operations and engineering, to socio-economics and energy policy perspectives. It thus covers practical issues such as silviculture, harvesting, processing, comparative cost estimates, public policy tools and market effects. As such the book provides a comprehensive review of the complex dimensions of wood energy as well as practical guidance for professionals, researchers and advanced students. It will also provide invaluable guidance for economic development agencies, practitioners and policy-makers, when evaluating the impacts of wider wood energy adoption as part of a strategy for sustainable energy generation. The main focus is on industrialised production and developed economies, particularly the USA and Europe.
Since the 1992 Earth Summit, there have been increased efforts on an international scale to address global climate change. Reducing the increased levels of CO2 and other "greenhouse gases," which are believed to be contributing to this climatic change, will require major effort on the part of the world's governments. This means that the environmental, economic, social, and political consequences of climate change must be understood, and that strategies to mitigate climate change must also address these issues.
Urban forestry includes not only the city -street, it includes city parks and recreation areas as well as suburban areas. It involves city planning, forestry for development, construction of an infrastructure to care and nurture trees, funding, and community action. This title deals with the aspects of managing all facets of these areas.
This title aims to provide introductory and concluding surveys of the subject of farms, trees and farmers. Two central parts explore trends in farmer tree-growing and the factors which influence decision-making. Eight case studies cover, among other topics, the need for tree products, market access, the allocation of land and labour, and exposure to risk. In showing why farmers decide to grow or not grow trees, it seeks to increase the reader's knowledge about farming systems and to provide a guide to encouraging farm forestry throughout the world.
This book traces the economic and biological pattern of forest development from initial settlement and harvest activity at the natural forest frontier to modern industrial forest plantations. It builds from diagrams describing three discrete stages of forest development, and then discusses the management and policy implications associated with each, supporting its observations with examples and data from six continents and from both developed and developing countries. It shows that characteristic distinctions between the three stages make forestry unusual in natural resource management and that effective policy requires different, even contrasting, decisions at each stage. William F. Hyde's comprehensive discussion covers a wide range of issues, including the impacts of both specific forest policies and broader macroeconomic policies, the unique requirements of current issues such as global warming, biodiversity and tourism, and the complexities of the different forest products industries. Concluding chapters review the roles of the newer institutional landowners, of smaller private and farm landowners, and of public agencies. This highly-original volume reaches far beyond forest economics; it explains what forestry can do for regional development and environmental conservation and what policies designed for other sectors and the macro-economy can do for forestry.
This is the first truly modern book solely devoted to seed reproduction of forest trees-from flowering to establishment, with emphasis on the interaction of environment with physiological processes.
The last decade saw dramatic concern for forest problems. The
future decades will witness an even more dramatic interest.
Certification of forests provides a guarantee to buyers of timber
products that their purchases come from well-managed forests that
will not support unsustainable or inequitable practices. This
produces multiple advantages to those with stakes in the entire
chain of production, not the least of which is justification of
their pricing. The Forest Certification Handbook is the first book
to fully assess the role of certification and provide practical
advice on developing, selecting and operating a program.
This edited book is a collection of information on recent advancements in remote sensing for forestry application. The main focus of this book is to address the novel applications in remote sensing in terms of recent techniques, sensors, methods and data collection. Remote sensing has been used for many decades. Today, remote sensing is heavily utilized in forest management, which is acquired from airborne and space-borne platforms using satellite data. In recent years, there have been rapid advances in the new types of sensors. The new generations of satellite sensors are introduced not only to provide important information on forest ecosystems, but also to improve the techniques and accuracies obtained by the traditional approaches. Researchers have become increasingly aware of the potential of remote sensing to address important forestry issues and challenges. The number of forestry publications using remote sensing has grown very rapidly, and this is noticeable with many recent technologies and applications. This book provides valuable source of reference to foresters, researchers, ecologists, climate change scientists and scholars who use remote sensing in their work. Furthermore, it serves as an academic book for undergraduate and graduate students of forestry, agriculture, natural resources and environmental sciences. The book demonstrates and engages the students how the new advancements in remote sensing technology and theory relate to the many real-world forestry applications. It gives readers deeper understanding on how remote sensing has come a long way and evolved into a mature science in the past five decades.
Wood-pastures are important elements of European cultural identity and have an exceptional ecological value, yet they are in decline all over Europe. The structure of wood-pastures is strongly influenced by grazing and multiple other land uses and by local and regional environmental conditions. This book examines the diverse expressions of wood-pastures across Europe. It provides a new perspective, using a social-ecological framework to explore social and ecological values, governing institutions, threats and conservation approaches. It explores the major drivers of decline, which are shown to be related to accelerated cultural, institutional and developmental changes occurring across Europe over the past century. Case studies are included from North-Western, Southern, and Eastern Europe. Written by renowned scholars and conservationists, the book contributes to developing better, locally adapted conservation policies and management approaches for wood-pastures.
The world's forests are disappearing at an alarming rate, and with disastrous consequences. Demand for wood and paper products ranks high amongst the causes of deforestation and forest degradation, and is now the major cause of loss in those forests richest in wildlife. There is a great deal to be done to improve the timber industry before our forests are safely and sustainably managed. Bad Harvest presents an incisive account of the role that the timber trade has played in the loss and degradation of forests around the world. It examines the environmental consequences of the trade on boreal, temporal and tropical regions, and its impacts for local people working and living in the forests. It also looks at the changing nature of the trade, and assesses current national and international initiatives to address the impacts of deforestation. Finally, the authors show how things could be improved in the future, by presenting a new strategy for sustainable forest management. Based on 15 years of extensive research - particularly work carried out by the World Wide Fund for Nature - Bad Harvest is essential reading on the subject; not only for environmentalists, but also for those in the timber trade seeking to improve the management and reputation of their product.
The Marcell Experimental Forest (MEF) in Minnesota serves as a living laboratory and provides scientists with a fundamental understanding of peatland hydrology, acid rain impacts, nutrient and carbon cycling, trace gas emissions, and controls on mercury transport in boreal watersheds. Its important role in scientific research continues to grow as the data gathered offers invaluable insight into environmental changes over the last century and goes far in answering many of today's pressing questions at landscape and global scales. Synthesizing five decades of research, Peatland Biogeochemistry and Watershed Hydrology at the Marcell Experimental Forest includes hundreds of research publications, dozens of graduate theses, and even some previously unpublished studies. Research at the MEF has been at the forefront of many scientific disciplines and these 15 chapters offer the depth and breadth of long-term studies on hydrology, biogeochemistry, ecology, and forest management on peatland watersheds at the MEF. Focusing on peatlands, lakes, and upland landscapes, the book begins with the pioneering research on hydrology done during the 1960s. It presents the innovative 1970's studies of atmospheric deposition; the 1980's research into nutrient cycles including carbon, nitrogen, and methane emissions; and the 1990's investigations into mercury deposition. The book concludes with a look at the latest and on-going studies such as this century's research into controls on methylmercury production and landscape-level carbon storage and cycling. Covering 50 years of research and written by a veritable who's who in peatland and forestry science, this important milestone in the collection of ecological data highlights bright prospects for future research, including the continuation of existing long-term measurements, the initiation of new monitoring programs, and plans for unprecedented studies on climate change.
An important prerequisite for successful conservation is a good understanding of what we seek to conserve. Nowhere is this more the case than in the fight to protect plant biodiversity, which is threatened by human activity in many regions worldwide. This book is written in the belief that tools that enable more people to understand biodiversity can not only aid protection efforts but also contribute to rural livelihoods. Among the most important of those tools is the field guide. Plant Identification provides potential authors of field guides with practical advice about all aspects of producing user-friendly guides which help to identify plants for the purposes of conservation, sustainable use, participatory monitoring or greater appreciation of biodiversity. The book draws on both scientific and participatory processes, supported by the experience of contributors from across the tropics. It presents a core process for producing a field guide, setting out key steps, options and techniques available to the authors of a guide and, through illustration, helps authors choose methods and media appropriate to their context.
Learn about the incredible range of useful shrubs for many different situations, large and small. World renown expert, Martin Crawford, includes common fruit bushes like currants and gooseberries, and many other less-known shrubs with edible fruits, nuts, leaves, or other parts. He takes us on a journey into the world of exotic spice trees, shrubs with medicinal parts, and plants that fix nitrogen to help fertilise other plants. All these can be grown in temperate climates, diversifying our diets, enabling us to design beautiful, productive gardens, as well as showing us how we can integrate agroforestry into our smallholdings and farms to create new income streams. Despite increasingly urgent calls from scientists, the not-fit-for-purpose economic and political systems we live in cannot be relied upon to implement the carbon emission reductions needed. This where we come into it: Whether we are farmer, gardener or plant dabbler, by planting shrubby plants that sequester carbon, we can minimise our carbon footprint and ideally live a carbon-negative life. On a broadscale, perennial and woody species are the way forward to reduce carbon emissions in agriculture. Woody crops sequester carbon in their biomass, but can also be grown in systems which allow for sequestration of large amounts of carbon into the soil.
