"The PhD thesis written by Mr. Ackermann is an outstanding and in-depth scientific study that closes a research gap and paves the way to new developments. Despite the extremely complex issues, his work is very understandable and excellently elaborated." Prof. Dr. Christiane Schmullius "The PhD thesis written by Mr. Ackermann is an excellent and very comprehensive work performed at the highest scientific level. It examines in detail the potential of SAR data with regards to the derivation of forest stem volume in the temperate latitudes. The work belongs to a technically complex field. Nevertheless, Mr. Ackermann has succeeded in presenting the content in a clear and understandable way." Dr. Christian Thiel "The proposed document is overall of very good quality. Mr. Ackermann has done an exhaustive analysis of the in-situ data available on the Thuringian forest and was able to derive Growing Stocking Volume using L- and X-band spaceborne SAR data. The document is very well structured with a good split of information between the core of the text presented in the 6 chapters and the 4 annexes, which contain detailed results. Mr. Ackermann's English grammar is excellent and his syntax is crystal clear, making his document pleasant to read. The way arguments are presented is logical and Mr. Ackermann gives a lot of attention to ensuring that sound explanations properly support these arguments." Dr. Maurice Borgeaud

A new era in wildland fuel sciences is now evolving in such a way that fire scientists and managers need a comprehensive understanding of fuels ecology and science to fully understand fire effects and behavior on diverse ecosystem and landscape characteristics. This is a reference book on wildland fuel science; a book that describes fuels and their application in land management.  There has never been a comprehensive book on wildland fuels; most wildland fuel information was put into wildland fire science and management books as separate chapters and sections.  This book is the first to highlight wildland fuels and treat them as a natural resource rather than a fire behavior input. Moreover, there has never been a comprehensive description of fuels and their ecology, measurement, and description under one reference; most wildland fuel information is scattered across diverse and unrelated venues from combustion science to fire ecology to carbon dynamics.  The literature and data for wildland fuel science has never been synthesized into one reference; most studies were done for diverse and unique objectives.  This book is the first to link the disparate fields of ecology, wildland fire, and carbon to describe fuel science. This just deals with the science and ecology of wildland fuels, not fuels management. However, since expensive fuel treatments are being planned in fire dominated landscapes across the world to minimize fire damage to people, property and ecosystems, it is incredibly important that people understand wildland fuels to develop more effective fuel management activities.

Forest soil characteristics are not only unique but their interpretation also differs from cropland soils. Just as there are diverse forest types, there are many soil variants that need different management. Today, forest plantations are being intensively managed for profitable timber, pulpwood and energy production. Site selection, species selection, site productivity evaluation, silvicultural treatments, and soil amendments need crucial soil information. This book provides a comprehensive overview of the physical, chemical and biological properties of forest soils and their implications on forest vegetation. Topics discussed include: major forest types of the world and their associated soils; forest biomass and nutrient dynamics; organic matter turnover and nutrient recycling; forest soil disturbance; forest soil and climate change; and forest soil management and silvicultural treatments.

This book provides an overview of the complex challenges and opportunities related to forest-based rural development in the tropics and subtropics. Applying a socio-ecological perspective, the book traces the changing paradigms of forestry in rural development throughout history, summarizes the major aspects of the rural development challenge in forest areas and documents innovative approaches in fields such as land utilization, technology and organizational development, rural advisory services, financing mechanisms, participative planning and forest governance. It brings together scholars and practitioners dealing with the topics from various theoretical and practical angles. Calling for an approach that carefully balances market forces with government intervention, the book shows that forests in rural areas have the potential to provide a solid foundation for a green global economy.

Climate change, urban sprawl, abandonment of agriculture, intensification of forestry and agriculture, changes in energy generation and use, expansion of infrastructure networks, habitat destruction and degradation, and other drivers of change occur at increasing rates. They affect patterns and processes in forest landscapes, and modify ecosystem services derived from those ecosystems. Consequently, rapidly changing landscapes present many new challenges to scientists and managers. While it is not uncommon to encounter the terms "global change" and "landscape" together in the ecological literature, a global analyses of drivers of change in forest landscapes, and their ecological consequences have not been addressed adequately. That is the goal of this volume: an exploration of the state of knowledge of global changes in forested landscapes with emphasis on causes and effects, and challenges faced by researchers and land managers. Initial chapters identify and describe major agents of landscape change: climate, fire, and human activities. The next series of chapters address implications of changes on ecosystem services, biodiversity conservation and carbon flux. A chapter that describes methodologies of detecting and monitoring landscape changes is presented followed by chapter that highlights the many challenges forest landscape managers face amidst of global change. Finally, we present a summary and a synthesis of the main points presented in the book. Each chapter will contain the individual research experiences of chapter authors, augmented by review and synthesis of global scientific literature on relevant topics, as well as critical input from multiple peer reviewers.

A global synthesis of the impacts of wildfires and controlled burning on insects, bringing together much hitherto scattered information to provide a guide to improved conservation management practice. The great variety of responses by insect species and assemblages demonstrates the often subtle balance between fire being a severe threat and a vital management component. Examples from many parts of the world and from diverse biotopes and production systems display the increasingly detailed appreciation of fire impacts on insects in terrestrial and freshwater environments and the ways in which prescribed burning may be tailored to reduce harmful ecological impacts and incorporated into protocols for threatened species and wider insect conservation benefits.

This book explores the specifically human dimensions of the problem posed by a new generation of invasive pests and pathogens to tree health worldwide. The growth in global trade and transportation in recent decades, along with climate change, is allowing invasive pests and pathogens to establish in new environments, with profound consequences for the ecosystem services provided by trees and forests, and impacts on human wellbeing. The central theme of the book is to consider the role that social science can play in better understanding the social, economic and environmental impacts of such tree disease and pest outbreaks. Contributions include explorations of how pest outbreaks are socially constructed, drawing on the historical, cultural, social and situated contexts of outbreaks; the governance and economics of tree health for informing policy and decision-making; stakeholder engagement and communication tools; along with more philosophical approaches that draw on environmental ethics to consider 'non-human' perspectives. Taken together the book makes theoretical, methodological and applied contributions to our understanding of this important subject area and encourages researchers from across the social sciences and humanities to bring their own disciplinary perspectives and expertise to address the complexity that is the human dimensions of forest and tree health.

Forest canopies not only support high terrestrial biodiversity but also represent a critical interface between the atmosphere and the earth. They provide goods and services to support diverse human communities and offer opportunities to explore sustainable use of these resources for many generations of local livelihoods. Forest canopies are important carbon sequestration units, and in this sense, serve as climate control for the planet. Canopies are important energy production centers for the planet, and serve as the basis for many food chains. The canopy can also act as a hook for education outreach and conservation, inspiring ecotourism through recreation and other sustainable uses such as treetop walks, zip lines, and birding. Despite these critical services provided by forest canopies, almost no dedicated research in the treetops was initiated until as recently as the late 1970s when single rope techniques were developed by mountaineering professionals and adapted for use in the canopy. Subsequently, an array of canopy access tools was designed in the 1980s and early 1990s that have opened up this "eighth continent" for global exploration and discovery. This volume uses the major findings of the 5th international canopy conference as a platform for organization, but it does not mimic the sessions and presentations of the conference itself. Instead, it builds on the important themes that emerged from the conference and solicits articles that represent future priorities and advancements for canopy science in the next decade. Despite the global efforts of hundreds of forest scientists over the past 3 decades, forests are degrading at an accelerated rate and biodiversity is increasingly threatened by human activities. Given these trends - despite the very best efforts of the world's best scientists - other approaches must be taken. This volume summarizes the issue of "treetops at risk" and assembles a global authorship to examine past accomplishments and future initiatives critical in forest conservation.

This book provides a comprehensive review of Grain for Green, China's nationwide program which pays farmers to revert sloping or marginal farm land to trees or grass. The program aims to improve the ecological conditions of much of China, and the socioeconomic circumstances of hundreds of millions of people. GfG is the largest reforestation, ecological restoration, and rural development initiative in history, combining the biggest investment, the greatest involvement, and the broadest degree of public participation ever. The book is organised in three sections. Part One reviews the history of land management in China from 1949 to 1998, exploring the conditions that led to the introduction of GfG, and comparing it to other reforestation programs. Part Two offers an overview of GfG, describing the timeline of the program, compensation paid to farmers, the rules concerning land and plant selection, the extent to which these rules were followed, the attitudes of farmers towards the program, and the way in which the program is organized and implemented by various state actors. Part Three discusses the impact of the GfG, from both ecological and socio-economic standpoints, looking at the economic benefits that result from participating in the GfG, the impact of the GfG across local economies, the redistribution of the labor force and the sustainability of the program, in particular the question of what will happen to the converted land when payments to farmers end.

For more than 40 years I have been engaged in timberline research. Thus, one could suppose that writing this book should not have been too difficult. It was harder, however, than expected, and in the end I felt that more questions had arisen than could be answered within its pages. Perhaps it would have been easier to write the book 30 years ago and then leave the subject to mature. Lastly it was the late Prof. Heinz Ellenberg who had convinced me to portray a much needed and complete picture of what we know of the timberline with special respect to its great physiognomic, structural and ecological variety. The first version of this book was p- lished in the German language (Holtmeier, 2000). Nevertheless, I was very delighted when Prof. Martin Beniston encouraged me to prepare an English edition for the series 'Advances in Global Change Research', which guaranteed a wider circulation. Timberline is a worldwide and very heterogeneous phenomenon, which can only be presented by way of examples. My own field experience is necessarily limited to certain timberline areas, such as the Alps, northern Scandinavia, northern Finland and many high mountain ranges in the western United States and Canada. However, my own observations and the results of my and my previous collaborators research were essential for developing the concept of the book and became integrated into the picture of timberline that is presented in the following chapters.

Forest gardening is a way of working with Nature which is not only productive and requires minimal maintenance, but creates great environmental benefits. As Herbert Girardet says in his Foreword, "Robert Hart was a rare person . . . For decades he waged a battle for life, patiently writing books and articles and quietly planting trees on his small farm in Shropshire. Robert created a magnificent forest garden which had a profound influence on the way people cultivated their land. It was a garden dedicated to human needs for fruit, nuts, vegetables and plant medicines. But it was at the same time a celebration of the myriad interactions of life, based on profound observations, both intuitive and scientific, of how different life forms interact in order to stimulate and support one another."

This book addresses the livelihood impacts of climate change, vulnerability and adaptation measures on the forest dependent communities of India. Research presented here focuses on three different agro-climatic areas of West Bengal, namely the coastal Sundarban, the drought-prone region and the mountainous region. Readers will discover the main climate induced vulnerabilities that affect livelihoods of forest communities, understand how to evaluate the expected impacts of climate change at different levels under different climate change scenarios, and be able to assess and measure the implied major social, environmental and economic impacts. Particular attention is also given to the role of the Indian governmental policy (including national forest policy of 1988) to reduce climate-related vulnerabilities. Chapters also highlight two main approaches to vulnerability assessment in socio-ecological systems. The first is the impact-based approach, which assesses the potential impacts of climate change on forest dependent people. The second is the vulnerability-based approach, which assesses social sensitivity and adaptive capacity to respond to stresses. Development practitioners, government implementing agencies, and researchers in environmental science and policy will find this book appealing.

Nearing the end of a lifetime in the boreal forest, a retired forester writes a passionate plea for rational, science-based forest management. The boreal forest is constantly changing, often dramatically. We like to picture it as a stable, balanced system. Really, it is anything but stable. The boreal forest is dynamic. For over sixty years, forester Malcolm F. Squires has seen mature forests within protected areas devastated by insects, moose, wind, and wildfire. While the forests often return from this destruction, they are never quite the same. A naturally balanced boreal forest is a human notion that does not match the reality of nature. If we don’t soon recognize and accept that reality and stop making irrational demands that a forest be “protected� from change or human management, we may be dooming them to disaster.

This volume explores the various functions and potential applications of mycorrhizas, including topics such as the dynamics of root colonization, soil carbon sequestration and the function of mycorrhizas in extreme environments. Some contributions focus on the use of arbuscular mycorrhizal fungi in various crop production processes, including soil management practices, their use as biofertilizers and in relation to medicinal plants. Other chapters elucidate the role of arbuscular mycorrhizal fungi in the alleviation of plant water stress and of heavy metal toxicity, in the remediation of saline soils, in mining-site rehabilitation and in the reforestation of degraded tropical forests. In addition to their impact in ecosystems, the economic benefits of applying arbuscular mycorrhizal fungi are discussed. A final chapter describes recent advances in the cultivation of edible mycorrhizal mushrooms.

In view of the grave consequences of soil degradation on ecosystem functions, food security, biodiversity and human health, this book covers the extent, causes, processes and impacts of global soil degradation, and processes for improvement of degraded soils. Soil conservation measures, including soil amendments, decompaction, mulching, cover cropping, crop rotation, green manuring, contour farming, strip cropping, alley cropping, surface roughening, windbreaks, terracing, sloping agricultural land technology (SALT), dune stabilization, etc., are discussed. Particular emphasis is given to soil pollution and the methods of physical, chemical and biological remediation of polluted soils. This book will lead the reader from the basics to a comprehensive understanding of soil degradation, conservation and remediation.

This book sheds new light on the causes and consequences of elephant migration in the Panchet Forest Division of Bankura District in West Bengal, India- an area characterized by fragmented forested landscape modified by agriculture and settlement expansion. Anthropogenic activities result in the decline in quality and coverage of forests, loss of biodiversity and removal of forest corridors which ultimately restrict or modify the movement of elephants causing a forceful change of their habitats. A major objective of this monograph is to identify the characteristics of man-elephant conflicts in terms of land use change, cropping patterns, ecological characteristics of the fragmented dry deciduous forest, trends and patterns of elephant migration, and livelihood patterns of the inhabitants in the affected areas. Readers will discover insights into changes in the behavioral pattern of elephants and local people in the conflict ridden zones, and how this influences food selection. Through this book we also learn about rational management strategies that can be employed on the local and national level to mitigate human-elephant conflicts. Ecologists, landscape conservation planners and environmental managers engaged in the conservation of large vertebrates in fragmenting and human-dominated landscapes will find this book valuable.

The work describes the general ecological aspects of Iran as well as West and Central Asia in the introduction. The book includes three chapters, each describing the climate, geology and soil characteristics, vegetation and forest types, site demands of the main tree species and the ecogram of them, management and socio-economic issues of three different phytogeographical regions, mainly the Hyrcanian, Irano-Turanian, and Saharo-Sindian. Each chapter contains a table for introducing the English and Botanical names of the plant species mentioned in the chapter. The information presented in this book is based on personal experiences and results of research projects of the authors, as well as experiences of other forest scientists in Iran. The references are given at the end of each chapter separately. The book contains 10 tables, 37 black and white and 55 color pictures.

There is currently much interest in mainstreaming gender in natural resource management, including forestry. This reader provides a collection of key articles on gender and forests published over the last 30 years. Including an editorial introduction and overview, it provides an accessible collection of excellent forestry-relevant social science within an overarching analytical framework and demonstrates the leading debates in the field. The book will be of great value to both biophysical science and social science students and to professionals in training. It focuses on people and forest interactions, providing a range of studies from both developed and developing countries. It includes theoretical analyses, methodological pieces, case studies, and cross-country comparisons, and it forms a companion volume to Gender and Forests: Climate Change, Tenure, Value Chains and Emerging Issues (2016).

The purpose of this book is to assess the potential effects of biotechnological approaches particularly genetic modification on biodiversity and the environment. All aspects of biodiversity such as ecological diversity, species diversity and genetic diversity are considered. Higher organisms contain a specific set of linear DNA molecules called chromosomes and a complete set of chromosomes in an organism comprises its genome. The collection of traits displayed by any organism (phenotype) depends on the genes present in its genome (genotype). The appearance of any specific trait also will depend on many other factors, including whether the gene(s) responsible for the trait is/are turned on (expressed) or off, the specific cells within which the genes are expressed and how the genes, their expression and the gene products interact with environmental factors. The primary biotechnology which concerns us is that of genetic manipulation, which has a direct impact on biodiversity at the genetic level. By these manipulations, novel genes or gene fragments can be introduced into organisms (creating transgenics) or existing genes within an organism can be altered. Transgenics are a major area of concern, combining genes from different species to effectively create novel organisms. Current rates of disappearance of biological and cultural diversity in the world are unprecedented. Intensive resource exploitation due to social and economic factors has led to the destruction, conversion or degradation of ecosystems. Reversing these trends requires time to time assessment to integrate conservation and development.

This book delivers current state-of-the-science knowledge of tree ecophysiology, with particular emphasis on adaptation to a novel future physical and chemical environment. Unlike the focus of most books on the topic, this considers air chemistry changes (O3, NOx, and N deposition) in addition to elevated CO2 effects and its secondary effects of elevated temperature. The authors have addressed two systems essential for plant life: water handling capacity from the perspective of water transport; the coupling of xylem and phloem water potential and flow; water and nutrition uptake via likely changes in mycorrhizal relationships; control of water loss via stomata and its retention via cellular regulation; and within plant carbon dynamics from the perspective of environmental limitations to growth, allocation to defences, and changes in partitioning to respiration. The authors offer expert knowledge and insight to develop likely outcomes within the context of many unknowns. We offer this comprehensive analysis of tree responses and their capacity to respond to environmental changes to provide a better insight in understanding likelihood for survival, as well as planning for the future with long-lived, stationary organisms adapted to the past: trees.

On a Sustainable Future of the Earth's Natural Resources is divided into three sections, with individual chapters contributed by experts on diff erent facets of the earth sciences, natural resources management and related issues. The first section focuses on the status of Earth's resources; land, water, biota and atmosphere. Reviews on the rate of exploitation and the need to conserve these resources for future sustenance are also covered in this section. Th e following section includes chapters elucidating environmental, ecological, climatological and anthropological pressures on sustained nourishment with the Earth's resources. The last section describes management practices, issues and perspectives on sociological, legal, administrative, ICT and strategic efforts that need to be implemented in order to sustain our natural resources. This book covers a broad spectrum of the Earth's resources and sustenance, offering a comprehensive perspective on their past, present and future.

Sustainable development and rural policies have pursued strategies where farming has been often regarded as a factor deteriorating the ecosystem. But the current economic, social and environmental problems of the Earth probably call for examples of a positive integration between human society and nature. This research work presents more than a hundred case studies where the historical relationships between man and nature have generated, not deterioration, but cultural, environmental, social and economic values. The results show that is not only the economic face of globalization that is negatively affecting the landscape, but also inappropriate environmental policies. The CBD-UNESCO program on biocultural diversity, the FAO Globally Important Agricultural Heritage Systems and several projects of the International Union of Forest Research Organizations, as well as European rural policies acknowledge the importance of cultural values associated to landscape. This research intends to support these efforts.

While restoration ecology has traditionally aimed to re-create some putative more 'natural' ecological state, forest landscape restoration (FLR) has emerged over the last decade as an approach aimed more at restoring natural functions, while focusing on meeting human needs. With a view to exploring the practical potential of this approach, this book draws together a team of experts from the natural and social sciences to discuss its success so far in addressing critical issues such as biodiversity, ecological function, and human livelihoods. Applying principles of landscape ecology, restoration ecology, planning theory and conflict management, the book presents a series of case studies which document the approach, and discusses how the approach can help with priority setting for the future. The book will provide a valuable reference to graduate students and researchers interested in ecological restoration, forest ecology and management, as well as to professionals in environmental restoration, natural resource management, conservation, and environmental policy.

Completing the primary genomic sequence of Arabidopsis thaliana was a major milestone, being the first plant genome and well established as the premiere model species in plant biology. Since working drafts of rice (Oryza sativa L.) genome became available (Yu et al. 2002), it has become the s- ond-best model organism in plants representing monocotyledons. Understanding how the genome sequence comprehensively encodes de- lopmental programs and environmental responses is the next major ch- lenge for all plant genome projects. This requires functional characterization of genes, including identification of regulatory sequences. Several functional genomics approaches were initiated to decode the linear sequence of the model plant Arabidopsis thaliana, including full-length cDNA collections, microarrays, natural variation, knockout collections, and comparative sequence analysis (Borevitz and Ecker 2004). Genomics provides the ess- tial tools to speed up the research work of the traditional molecular gene- cist, and is now a scientific discipline in its own right (Borevitz and Ecker 2004).
