This international rigorously peer-reviewed volume critically synthesizes current knowledge in forest hydrology and biogeochemistry. It is a one-stop comprehensive reference tool for researchers and practitioners in the fields of hydrology, biogeoscience, ecology, forestry, boundary-layer meteorology, and geography. Following an introductory chapter tracing the historical roots of the subject, the book is divided into the following main sections: . Sampling and Novel Approaches . Forest Hydrology and Biogeochemistry by Ecoregion and Forest Type . Hydrologic and Biogeochemical Fluxes from the Canopy to the Phreatic Surface . Hydrologic and Biogeochemical Fluxes in Forest Ecosystems: Effects of Time, Stressors, and Humans The volume concludes with a final chapter that reflects on the current state of knowledge and identifies some areas in need of further research.

Plant geographical description of the area, syntaxonomy, spatial patterns, floristic richness, structure of plant communities in relation to soil properties and herbivore influence were described for a mountain region that is difficult to access. Seasonal, inter-annual, and long-term dynamics of vegetation are discussed on the base of long-term observations as well as pollen and phytolith analyses. Population biology of alpine plants is studied by combination of field observations and mathematical modelling. Plant population strategies and soil seed banks are described for alpine plants from several communities. Results of long-term ecological experiments (plant reciprocal transplantations, dominant removals, light limitation) showed the significance of competition and facilitation for community organization. Structure of soil algal and fungal communities is represented as well as mycorrhiza of alpine plants. Main animal groups (wild) history and modern nature conservation problems are discussed.
leading to an overall decrease in the world's forest cover. The forests of Asia, in particular, have been strongly impacted. A number of initiatives have suggested forest policy reforms, and the need for the sustainable management of forests has been widely recognized and encouraged. But because implementation of reforms at the local level has been insufficient, it is imperative that local people begin to effectively participate in forest planning and management as well as in protected-area management. The Forest Conservation Project, launched in April 1998 by the Institute for Global Environmental Strategies (IGES), has carried out research activities on forest strategies, including policy analysis and on-site surveys. This book gives an overview of the project's research activities in its first three-year phase (April1998-March 2001). Since viable forest strategies work best when based on the involvement of local people, this report is addressed to stakeholders in the communities of the relevant countries, including local people and authorities, community-based organizations, experts, national agencies, and international institutions.
From killer fires to ecosystem rehabilitation, an exhaustive survey exploring the ecological, social, and economic consequences of managing fires in U.S. wildland areas. Fire management involves protecting natural resources from fire but also using controlled burning for land management purposes. Who are the stewards of land management and the researchers who devote their entire careers studying fire? How are ecosystems restored after major fires? What are the economic ramifications and what assessment tools are available? Forest Fires: A Reference Handbook explores the historical, ecological, economic, and social dimensions of wildland combustion and their impacts in North America. Explaining how legislation and public perception have been shaped by historic fires and fire seasons, particular emphasis is placed on the summer of 2000 as a way of understanding and managing future fires. Provides a detailed chronology of events, legislative acts, policy controversies, and precedents for fire management in the United States, illustrating how the fires discussed reflect a continuation of trends established in the 20th century and before Includes biographies of past and present forest fire management leaders, scientists, academicians, and policy makers
Forestry has been witness to some dramatic changes in recent years, with several Western countries now moving away from the traditional model of regarding forests merely as sources of wood. Rather these countries are increasingly recognizing their forests as multi-purpose resources with roles which go far beyond simple economics. In this innovative book, Sylvie Nail uses England as a case study to explore the relationships between forests, society and public perceptions, raising important questions about forest policy and management both now and in the future. Adopting a sociological approach to forest policy and management, the book discusses the current validity of the two principles underlying forestry since the Middle Ages: first, that forestry should only exist when no better use of the land can be made, and second, that forestry itself should be profitable. The author stresses how values and perceptions shape policies, and conversely how policies can modify perceptions, and also how policies can fail if they do not take perceptions into account. She concludes that many of the issues facing English forestry in the 21st century - from leisure, health and amenity provision, through education and rural as well as urban regeneration, to biodiversity conservation - go well beyond both national borders and the scope of forestry. Indeed forestry in the 21st century seems to be less about planting and managing trees than about being a vector and a mirror of social change. This novel synthesis provides a valuable resource for advanced students and researchers from all areas of natural resource studies, including those interested in social history, socio-economics, cultural geography and environmental psychology, as well as those studying landscape ecology, environmental history, policy analysis and natural resource management.
Forest ecosystems represent a major type ofland use in Germanyand in Europe. They provide a number of functions, or ecosystem services, beneficial to humans, namely biomass production, regulation of the water- and energy cyde, C and N sequestration, erosion control, recreation, and they act as habitat for numerous species. The stability of forest ecosystems in Europe as influenced by the deposition of air pollutants has been a matter of debate for more than 20 years. Besides atmospheric deposition, other environmental conditions affecting forest ecosystems, such as temperature, CO content of the atmosphere 2 and precipitation, have significantly changed in the past and continue to change in the future. Quantifying and predicting the effects of these changes on ecosys tem functioning are achallenge to ecosystem research and also a requirement to establish sustainable use of forest ecosystems in the future. This book summarizes results of long-term, interdisciplinary ecosystem research conducted in two forested catchments and coordinated at the Bayreuth Institute of Terrestrial Ecosystem Research (BITOEK), University of Bayreuth, Germany. It does not aim to summarize all the research of BITOE K in the past decade, which would go far beyond the studies in these two catch ments. Instead, we concentrate here on the long-term developments in the biogeochemistry of carbon and mineral elements and on the water cyde, at both the plot and the catchment scale.
Regional intercomparisons between ecosystems on different continents can be a powerful tool to better understand the ways in which ecosystems respond to global change. Large areas are often needed to characterize the causal mechanisms governing interactions between ecozones and their environments. Factors such as weather and climate patterns, land-ocean and land-atmosphere interactions all play important roles. As a result of the strong physical north-south symmetry between the western coasts of North and South America, the similarities in climate, coastal oceanography and physiography between these two regions have been extensively documented. High Latitude Rain Forests and Associated Ecosystems of the West Coast of the Americas presents current research on West Coast forest and river ecology, and compares ecosystems of the Pacific Northwest with those of South America.
Since the late 1960s the Indonesian state of East Kalimantan has witnessed a marked increase in the impact of human activities chiefly commercial logging and agricultural exploitation. Located on the island of Borneo, East Kalimantan also was subjected to prolonged droughts and extensive wildfires in 1982-83 and 1997-98 that were linked to the El Nino-Southern Oscillation (ENSO) phenomenon. The changes in the rainforest ecosystem in East Kalimantan during this 15-year cycle of severe ENSO events are the subject of this book. With an eye toward development of rehabilitation techniques for sustainable forest management, the authors examine possible interactive effects of drought, fire, and human impacts on the flora and fauna of the area.
The boreal forest is the northern-most woodland biome, whose
natural history is rooted in the influence of low temperature and
high-latitude. Alaska's boreal forest is now warming as rapidly as
the rest of Earth, providing an unprecedented look at how this
cold-adapted, fire-prone forest adjusts to change.
For a decade Philip Connors has spent nearly half of each year in a 7' x 7' fire lookout tower, 10,000 feet above sea level, keeping watch over one of the most fire-prone forests in America. Fire Season is his remarkable reflection on work, untamed fire, our place in the wild, and the charms of solitude. Written with narrative verve and startling beauty, and filled with heartfelt reflections on his literary forebears who also served as "freaks on the peaks"--among them Edward Abbey, Jack Kerouac, and Norman Maclean--Fire Season is a book to stand the test of time.
Ulrike Probstl, Veronika Wirth, Birgit Elands, and Simon Bell 1. 1 Background to the Study Ulrike Probstl and Simon Bell New directions and the need for reform - these two catch phrases dominate the political discussions around forests, forestry, and forest research in many European countries. In Germany there is concern about the reduction of university positions in forestry, as there is across Europe about the new, more economically ori- tated direction of forest management. For example, in 2004 the Bavarian electorate defeated a referendum about the restructuring of the forest administration, largely because of concern about changes to nature conservation and recreation mana- ment. Obviously, the new trends in forest management imposed by commercial interests stand in stark contrast to the overall expectations society has of effective multi-functional forest management (Deutscher Rat fur Landesp ege 2004). The administrative desires for reform on the one side and - often contradictory - societal demands on the other are the reason to undertake an investigation of the European model of multi-functional forest management.
Igapo forests are a common part of the Amazon whose ecosystems are critical to our shared human future. The introduction addresses the structure, function and dynamics of igapo forests in the Amazon basin, focusing on their uniqueness due to their high level of complexity defined as the many ways that different components of igapo forests in the Amazon basin ecosystem interact and also on how those interactions are on a higher-order compared to other tropical forests. The text then breaks down the igapo ecosystem using these sections: (1) Igapo forests over space and time, (2) Water, light and soils, (3) The carbon cycle, (4) Litter, fungi and invertebrates, (5) Vertebrates, (6) Plant population studies, (7) Plant community studies, and (8) Human impacts and management. Experts from around the world serve as chapter authors that review what is known about their specific part of the igapo ecosystem, what research they have done, and also what needs to be done in the future.
Riparian forests along streams and rivers are diverse in species, structure, and regeneration processes, and have important ecological functions in maintaining landscape and biodiversity. This book discusses riparian forests from subpolar to warm-temperate zones, covering headwater streams, braided rivers on alluvial fans, and low-gradient meandering rivers. It presents the dynamics and mechanisms that govern the coexistence of riparian tree species, tree demography, the response to water stress of trees, and the conservation of endangered species, and focuses on natural disturbances, life-history strategies, and the ecophysiology of trees. Because many riparian landscapes have been degraded and are disappearing at an alarming rate, the regeneration of the remaining riparian ecosystems is urgent. With contributions by more than 20 experts in diverse fields, this book offers useful information for the conservation, restoration, and rehabilitation of riparian ecosystems that remain in world streams and rivers.
Who has rights to forests and forest resources? In recent years governments in the South have transferred at least 200 million hectares of forests to communities living in and around them . This book assesses the experience of what appears to be a new international trend that has substantially increased the share of the world's forests under community administration. Based on research in over 30 communities in selected countries in Asia (India, Nepal, Philippines, Laos, Indonesia), Africa (Burkina Faso, Cameroon, Ghana) and Latin America (Bolivia, Brazil, Guatemala, Nicaragua), it examines the process and outcomes of granting new rights, assessing a variety of governance issues in implementation, access to forest products and markets and outcomes for people and forests . Forest tenure reforms have been highly varied, ranging from the titling of indigenous territories to the granting of small land areas for forest regeneration or the right to a share in timber revenues. While in many cases these rights have been significant, new statutory rights do not automatically result in rights in practice, and a variety of institutional weaknesses and policy distortions have limited the impacts of change. Through the comparison of selected cases, the chapters explore the nature of forest reform, the extent and meaning of rights transferred or recognized, and the role of authority and citizens' networks in forest governance. They also assess opportunities and obstacles associated with government regulations and markets for forest products and the effects across the cases on livelihoods, forest condition and equity.Published with CIFOR
Much of the world's tropical timber is still supplied from natural forest, but under current systems of management the forests are rapidly becoming exhausted. Unless management practices change to become genuinely sustainable, neither the forests nor the essential contribution of the timber industry to many economies will survive. Duncan Poore reviews the extent to which natural forests are already being sustainably managed for timber production, and looks at how these practices can be enlarged. He places management for timber in the wider context of tropical forest conservation and outlines a strategy for further action. Thoroughly researched and accessibly written, this book will be useful for everyone working or interested in the subject of tropical forests. Foreword by Dato Dr B.C.Y.

With a population of more than eighteen million people, Mexico City is a major metropolitan area where the effects of urban development on air quality are of immediate concern. Air pollution exposures and effects on forests in the Mexico City Air Basin are in many respects similar to those reported in the Los Angeles, California Air Basin. Studies of air pollution impacts on forests in these two regions may serve as models for urban areas all over the world. Although scientists have studied air pollution and its effects on forests and vegetation in the Mexico City Air Basin for years, this book reviews and synthesizes this body of work for the first time. This synthesis is particularly valuable as air pollution increases at an alarming rate along with global urbanization. A thorough discussion of regional geology, climate and hydrology, historical natural resource utilization, and sociological factors provide the context for evaluating air pollution impacts on the highly valued forests surrounding this megacity. The environmental and ecological consequences of chronic exposure to biologically important pollutants are considered in various case studies. Finally, the editors discuss the state of air pollution research in the Mexico City Air Basin and the outlook for the health and sustainability of forests within the Basin.
It has been increasingly recognized that trees and vegetation in urban areas provide a number of ecological services beyond beautifying cities. The purpose of urban forestry is to use trees and natural habitat patches to ameliorate negative environmental impacts of cities and to contribute to the creation of more livable, ecological sustainable eco-cities. Ecology, Planning, and Management of Urban Forests takes an international approach to sharing knowledge about the management of urban forests that has been learned through studies in many different regions. This allows the reader to evaluate methods and management that are appropriate for particular geographic, environmental and socio-political contexts. Urban forests are also approached on regional and landscape scales to encompass more natural environments in and around cities, rather than within arbitrary municipal boundaries.
This text argues that the scale of deforestation wrought by West African farmers during the 20th century has been vastly exaggerated and global analyses have unfairly stigmatized them and obscured their more sustainable, landscape-enriching practices. On a country by country basis (covering Sierra Leone, Liberia, Cote D'Ivoire, Ghana, Togo and Benin) and using historical and social anthropological evidence, it illustrates that more realistic assessments of forest cover change, and more respectful attention to local knowledge and practices, are necessary bases for effective and appropriate environmental policies.
The Forest Primary Production Research Group was born in the Department of S- viculture, University of Helsinki in the early 1970s. Intensive ?eld measurements of photosynthesis and growth of forest vegetation and use of dynamic models in the interpretation of the results were characteristic of the research in the group. Electric instrumentation was based on analogue techniques and the analysis of the obtained measurements was based on self-written programs. Joint research projects with the Research Group of Environmental Physics at the Department of Physics, lead by Taisto Raunemaa (1939-2006) started in the late 1970s. The two research groups shared the same quantitative methodology, which made the co-operation fruitful. Since 1980 until the collapse of the Soviet Union the Academy of Finland and the Soviet Academy of Sciences had a co-operation program which included our team. The research groups in Tartu, Estonia, lead by Juhan Ross (1925-2002) and in Petrozawodsk, lead by Leo Kaipiainen (1932-2004) were involved on the Soviet side. We had annual ?eld measuring campaigns in Finland and in Soviet Union and research seminars. The main emphasis was on developing forest growth models. The research of Chernobyl fallout started a new era in the co-operation between forest ecologists and physicists in Helsinki. The importance of material ?uxes was realized and introduced explicitly in the theoretical thinking and measurements. |
