Forests provide a large range of beneficial services, including tangible ones such as timber and recreation, and intangible services such as climate regulation, biodiversity, and watershed protection. On the other hand, forests can also be considered roadblocks to progress that occupy space more productively used for agriculture, making consideration of their regulating services crucial for balancing land use and forest loss. Monitoring forest cover and loss is critical for obtaining the data necessary to help define what is needed to maintain the varying forest service requirements in different parts of the world. There is an increasing need for timely and accurate forest change information, and consequently a greater interest in monitoring those changes. Global Forest Monitoring from Earth Observation covers the very recent developments undertaken for monitoring forest areas from global to national levels using Earth observation satellite data. It describes operational tools and systems for monitoring forest ecosystems, discussing why and how researchers currently use remotely sensed data to study forest cover and loss over large areas. The book introduces the role of forests in providing ecosystem services and the need for monitoring their change over time, followed by an overview of the use of earth observation data to support forest monitoring. It discusses general methodological differences, including wall-to-wall mapping and sampling approaches, as well as data availability. This book provides excellent coverage of the research and applications of forest monitoring, indicator mapping at coarse spatial resolution, sample-based assessments, and wall-to-wall mapping at medium spatial resolution using optical remote sensing datasets, such as MODIS and Landsat. It examines the use of radar imagery in forest monitoring and presents a number of operational systems, from Brazil's PRODES and DETER products to Australia's NCAS system. Written by leading global experts in the field, this book offers a launch point for future advances in satellite-based monitoring of global forest resources. It gives readers a deeper understanding of global forest monitoring methods and shows how state-of-the-art technologies may soon provide key data for creating more balanced policies.

Due to its height, density, and thickness of crown canopy; fluffy forest floor; large root system; and horizontal distribution; forest is the most distinguished type of vegetation on the earth. In the U.S., forests occupy about 30 percent of the total territory. Yet this 30 percent of land area produces about 60 percent of total surface runoff, the major water resource area of the country. Any human activity in forested areas will inevitably disturb forest floors and destroy forest canopies, consequently affecting the quantity, quality, and timing of water resources. Thoroughly updated and expanded, Forest Hydrology: An Introduction to Water and Forests, Third Edition discusses the concepts, principles, and processes of forest and forest activity impacts on the occurrence, distribution, and circulation of water and the aquatic environment. Brings water resources and forest-water relations into a single, comprehensive textbook Focuses on the concepts, processes, and general principles in forest hydrology Covers functions, properties, and science of water; water distribution; forests and precipitation, vaporization, stream flow, and stream sediment Discusses watershed management planning and practical applications of forest hydrology in resource management In a single textbook, Forest Hydrology: An Introduction to Water and Forests, Third Edition comprehensively covers water and water resources issues, forest characteristics relevant to the environment, forest impacts in the hydrological cycle, watershed research, watershed management planning, and hydrologic measurements. With the addition of new chapters, new issues, and appendices, this new edition is a valuable resource for upper-level undergraduates in forest hydrology courses as well as professionals involved in water resources management and decision-making in forested watersheds.

Globally rainforests are under threat on numerous fronts, including clearing for agriculture, harvesting for timber and urban expansion. Yet they have a crucial role in biodiversity conservation, climate change mitigation and providing other ecosystem services. As the term is used in this book, rainforests include both temperate and tropical, although the emphasis is on tropical rainforests. Rainforests are also attractive tourist spaces and where they have been used as a tourism resource have generated significant income for local communities. However not all use of rainforests as a tourism resource has been sustainable. This book argues that sustainability must be the foundation on which tourism use of this complex but ultimately fragile ecosystem must be built upon. It provides a multi-disciplinary perspective, incorporating rainforest science, management and tourism issues. The book is organized into four sections commencing with Rainforest Ecology and Management followed by People and Rainforests, Opportunities for Rainforest Tourism Development and finally Threats to Rainforests. Each major rainforest region is covered, including the Amazon, Central America, Africa, Australia and south-east Asia, in the context of a specific issue. For example rainforests in Papua New Guinea are examined in the context of community-based ecotourism development, while the rainforests in Borneo are discussed in an examination of wildlife issues. Other issues covered in this manner include governance, empowerment issues for rainforest peoples and climate change.

The studies in this volume provide an ethnography of a plantation frontier in central Sarawak, Malaysian Borneo. Drawing on the expertise of both natural scientists and social scientists, the key focus is the process of commodification of nature that has turned the local landscape into anthropogenic tropical forests. Analysing the transformation of the space of mixed landscapes and multiethnic communities-driven by trade in forest products, logging and the cultivation of oil palm-the contributors explore the changing nature of the environment, multispecies interactions, and the metabolism between capitalism and nature. The project involved the collaboration of researchers specialising in anthropology, geography, Southeast Asian history, global history, area studies, political ecology, environmental economics, plant ecology, animal ecology, forest ecology, hydrology, ichthyology, geomorphology and life-cycle assessment. Collectively, the transdisciplinary research addresses a number of vital questions. How are material cycles and food webs altered as a result of large-scale land-use change? How have new commodity chains emerged while older ones have disappeared? What changes are associated with such shifts? What are the relationships among these three elements-commodity chains, material cycles and food webs? Attempts to answer these questions led the team to go beyond the dichotomy of society and nature as well as human and non-human. Rather, the research highlights complex relational entanglements of the two worlds, abruptly and forcibly connected by human-induced changes in an emergent and compelling resource frontier in maritime Southeast Asia.

Large ungulates in tropical forests are among the most threatened taxa of mammals. Excessive hunting, degradation of and encroachments on their natural habitats by humans have contributed to drastic reductions in wild ungulate populations in recent decades. As such, reliable assessments of ungulate-habitat relationships and the spatial dynamics of their populations are urgently needed to provide a scientific basis for conservation efforts. However, such rigorous assessments are methodologically complex and logistically difficult, and consequently many commonly used ungulate population survey methods do not address key problems. As a result of such deficiencies, key parameters related to population distribution, abundance, habitat ecology and management of tropical forest ungulates remain poorly understood. This book addresses this critical knowledge gap by examining how population abundance patterns in five threatened species of large ungulates vary across space in the tropical forests of the Nagarahole-Bandipur reserves in southwestern India. It also explains the development and application of an innovative methodology - spatially explicit line transect sampling - based on an advanced hierarchical modelling under the Bayesian inferential framework, which overcomes common methodological deficiencies in current ungulate surveys. The methods and results presented provide valuable reference material for researchers and professionals involved in studying and managing wild ungulate populations around the globe.

Do you think identifying bats in Europe or in North America is difficult? Well, try it in the Amazon. The planet's green lung is home to the most diverse bat communities on the planet with more than 160 species currently described. Local species richness often surpasses 100 and for many, their identification in the field is, to say the least, challenging. This task will now become easier with the publication of the Field Guide to the Bats of the Amazon: a landmark handbook aimed at facilitating species identification in the field. The book, written and designed by an international bat research team mainly based in the University of Lisbon in collaboration with the National Institute of Amazonian Research (INPA), is a guide for anyone conducting field work on bats in the Amazon or interested in bat biodiversity. It is largely based on previous published keys with modifications derived from both personal observations and years of field experience in the Brazilian Amazon at the Biological Dynamics of Forest Fragments Project (BDFFP), as well as a thorough revision of available bat keys and species descriptions. The field guide also features the first acoustic key for Amazonian bats, illustrated with the echolocation spectrogram of most species. This represents a major step towards alleviating the daunting task of identifying the numerous species of aerial insectivorous bats that occur in the Amazon based on their echolocation calls. It further constitutes an important tool to improving the knowledge and optimizing surveys of aerial insectivorous Neotropical bats, a group which remains largely understudied. The field guide provides an essential tool, not only for researchers, but also for bat conservationists, consultancies and anyone interested in Neotropical bats in general, and Amazonian bats in particular.

For centuries, people have understood that forests, and our utilisation of them, influence the climate. With modern environmental concerns, there is now scientific, governmental, and popular interest in planting trees for climate protection. This book examines the historical origins of the idea that forests influence climate, the bitter controversy that ended the science, and its modern rebirth. Spanning the 1500s to the present, it provides a broad perspective across the physical and biological sciences, as well as the humanities, to explain the many ways forests influence climate. It describes their use in climate-smart forestry and as a natural climate solution, and demonstrates that in the forest-climate question, human and sylvan fates are linked. Accessibly written with minimal mathematics, it is ideal for students in environmental and related sciences, as well as anyone with an interest in understanding the environmental workings of forests and their interactions with climate.

Forest is a celebration of the diverse ways in which trees and forests are as magnificent, economically relevant and profoundly enchanting today as they ever have been.

Journeying across the continents, writer Matt Collins and photographer Roo Lewis tie together both the historical context and modern-day applications of some of the world's most fascinating and iconic trees. They explore the heritage of woodlands from around the world and meet those whose lives are inexplicably bound to them.

The book is divided into 10 main chapters, each of which explores a tree from a particular genus - Pine, Juniper, Oak, Hornbeam, Cherry, Beech, Birch, Chestnut, Douglas-fir and Poplar. Each chapter provides the reader with a short introduction to the tree, followed by a journalistic account of its relevance to modern day-life (from gin making on Isle of Islay to a truffle farm in Spain), and concludes with an account of the tree in its native forest (from hornbeams in the Ironwoods of Ontario to firs on Vancouver Island).

Captured on medium-format film, Roo's stunning, rich colour images are the perfect companion to Matt's engaging storytelling and botanical knowledge. Forest crafts a captivating interpretation of the story of the forest through the trees.

Wildland fires are among the most complicated environmental phenomena to model. Fire behavior models are commonly used to predict the direction and rate of spread of wildland fires based on fire history, fuel, and environmental conditions; however, more sophisticated computational fluid dynamic models are now being developed. This quantitative analysis of fire as a fluid dynamic phenomenon embedded in a highly turbulent flow is beginning to reveal the combined interactions of the vegetative structure, combustion-driven convective effects, and atmospheric boundary layer processes. This book provides an overview of the developments in modeling wildland fire dynamics and the key dynamical processes involved. Mathematical and dynamical principles are presented, and the complex phenomena that arise in wildland fire are discussed. Providing a state-of-the-art survey, it is a useful reference for scientists, researchers, and graduate students interested in wildland fire behavior from a broad range of fields.

Humans have influenced the landscapes and forests throughout the temperate and boreal zones for millennia. Restoration of Boreal and Temperate Forests, Second Edition focuses on the negative impact of human activity, and explains the importance of forest restoration as a way to repair habitat, restore forest structure and function, and counteract the lasting effects of humanity. The book offers broad geographic coverage, as well as a combination of review and case study chapters providing social and policy contexts for restoration of specific forest types. This revised edition begins with a historical context for restoration, provides a conceptual framework for understanding the relationship between degradation and restoration, and defines terms within that framework. While building on the first edition, it presents the response of restorationists to the current challenges of interpreting scattered science on forest history, stand development, and natural processes. It combines applicable experience designed to improve present and future ecological and social sustainability. Describes restoration in the context of rapid social, economic, environmental, and climate change Looks toward the future, presenting several completely new topics in forest restoration Covers different starting points for restoration, from non-forest to degraded forest Restoration of Boreal and Temperate Forests, Second Edition aids in the understanding of the diverse cultural and ecological contexts for restoration of temperate and boreal forests, and the creation of a better foundation of documented knowledge to support future and existing restoration decisions.

In popular discourse, tropical forests are synonymous with 'nature' and 'wilderness'; battlegrounds between apparently pristine floral, faunal, and human communities, and the unrelenting industrial and urban powers of the modern world. It is rarely publicly understood that the extent of human adaptation to, and alteration of, tropical forest environments extends across archaeological, historical, and anthropological timescales. This book is the first attempt to bring together evidence for the nature of human interactions with tropical forests on a global scale, from the emergence of hominins in the tropical forests of Africa to modern conservation issues. Following a review of the natural history and variability of tropical forest ecosystems, this book takes a tour of human, and human ancestor, occupation and use of tropical forest environments through time. Far from being pristine, primordial ecosystems, this book illustrates how our species has inhabited and modified tropical forests from the earliest stages of its evolution. While agricultural strategies and vast urban networks emerged in tropical forests long prior to the arrival of European colonial powers and later industrialization, this should not be taken as justification for the massive deforestation and biodiversity threats imposed on tropical forest ecosystems in the 21st century. Rather, such a long-term perspective highlights the ongoing challenges of sustainability faced by forager, agricultural, and urban societies in these environments, setting the stage for more integrated approaches to conservation and policy-making, and the protection of millennia of ecological and cultural heritage bound up in these habitats.

Sustainable Forest Management provides the necessary material to educate students about forestry and the contemporary role of forests in ecosystems and society. This comprehensive textbook on the concept and practice of sustainable forest management sets the standard for practice worldwide. Early chapters concentrate on conceptual aspects, relating sustainable forestry management to international policy. In particular, they consider the concept of criteria and indicators and how this has determined the practice of forest management, taken here to be the management of forested lands and of all ecosystems present on such lands. Later chapters are more practical in focus, concentrating on the management of the many values associated with forests. Overall the book provides a major new synthesis which will serve as a textbook for undergraduates of forestry as well as those from related disciplines such as ecology or geography who are taking a course in forests or natural resource management.

"An inspiring reminder of the incredible resource that is our public lands." --Brendan Leonard, author of The Camping Life and Surviving the Great Outdoors Across 193 million acres of forests, mountains, deserts, watersheds, and grasslands, national forests provide a multitude of uses as diverse as America itself. They welcome 170 million visitors each year to hike, bike, paddle, ski, fish, and hunt. But "the people's lands" offer more than just recreation. Lost habitats are recovered, timber is harvested, and endangered wildlife is protected as part of the Forest Service's enduring mission. In Our National Forests, Greg Peters gives an inside look at America's most important public lands and the people committed to protecting them and ensuring access for all. From the Forest Service growing millions of seedlings in the West each year, to their efforts to save the hellbender salamander in Appalachia, the story spans the breadth of the country and its diverse ecology. And people are at the center, whether the dedicated Forest Service members or the everyday citizens who support and tend to the protected lands near their homes. This complete look at America's national forests--their triumphs, challenges, controversies, and vital programs--is a must-read for everyone interested in the history of America's most important public lands.

This textbook provides an introduction to the field of mineral economics and its use in understanding the behaviour of mineral commodity markets and in assessing both public and corporate policies in this important economic sector. The focus is on metal and non-metallic commodities rather than oil, coal, and other energy commodities. The work draws on John Tilton's teaching experience over the last 30 years at the Colorado School of Mines and the Catholic University of Chile, as well as short courses for RioTinto and other mining companies. This is combined with the professional consulting and academic research of Juan Ignacio Guzman over the past decade, in order to demonstrate the industry application of the economic principles described in the earlier chapters. The book should be an ideal text for graduate and undergraduate students in the fields of mining engineering and natural resource economics and policy. It should also be of interest to professionals and investors in mining and commodity markets, and those undertaking continuing education in the mineral sector.

Shortlisted for the 2018 TWS Wildlife Publication Awards in the authored book category In recent years, conflicts between ecological conservation and economic growth forced a reassessment of the motivations and goals of wildlife and forestry management. Focus shifted from game and commodity management to biodiversity conservation and ecological forestry. Previously separate fields such as forestry, biology, botany, and zoology merged into a common framework known as conservation biology and resource professionals began to approach natural resource problems in an interdisciplinary light. Wildlife Habitat Management: Concepts and Applications in Forestry presents an integrated reference combining silvicultural and forest planning principles with principles of habitat ecology and conservation biology. With extensive references and case studies drawn from real situations, this book begins with general concepts such as habitat selection, forest composition, influences on habitat patterns, and the dynamics of disturbance ecology. It considers management approaches for specific habitats including even-aged and uneven-aged systems, riparian areas, and dead wood and highlights those approaches that will conserve and manage biodiversity. The author discusses assessment and prioritization policies, monitoring techniques, and ethical and legal issues that can have worldwide impact. Detailed appendices provide a glossary, scientific names, and tools for measuring and interpreting habitat elements. Writing in a species-specific manner, the author emphasizes the need to consider the potential effects of management decisions on biodiversity conservation and maintains a holistic approach throughout the book. Drawing from the author's more than 30 years working and teaching in natural resources conservation, Wildlife Habitat Management: Concepts and Applications in Forestry provides a synopsis of current preservation techniques and establishes a common body of knowledge from which to approach the conservation of biodiversity in the future.

Insects are the most abundant and diverse organisms that inhabit our planet and are found in all the world's forest ecosystems. Many feed and/or breed on parts of trees. Some perform important functions, such as pollination or break-down of dead vegetation. Others weaken, deform or kill trees, and compete with humans for the many goods and services that trees and forests provide. "Forest" "Entomology: A Global Perspective" examines forest insects in a global context and reviews their dynamics, interactions with humans and methods for monitoring and management of species that damage forests. Also provided are 235 profiles of forest insects, worldwide. A series of tables provides summaries of the distribution and hosts of many more species. Included are those that damage forests, others that are simply curiosities and some that are beneficial. This book is designed as a reference for students, practicing foresters and forest health specialists, especially for those who work internationally or are concerned with species that have the potential to expand their ranges via international trade, travel or environmental changes.

Rain forests represent the world's richest repository of terrestrial biodiversity, and play a major role in regulating the global climate. They support the livelihoods of a substantial proportion of the world's population and are the source of many internationally traded commodities. They remain (despite decades of conservation attention) increasingly vulnerable to degradation and clearance, with profound though often uncertain future costs to global society. Understanding the ecology of these diverse biomes, and peoples' dependencies on them, is fundamental to their future management and conservation.
Tropical Rain Forest Ecology, Diversity, and Conservation introduces and explores what rain forests are, how they arose, what they contain, how they function, and how humans use and impact them. The book starts by introducing the variety of rain forest plants, fungi, microorganisms, and animals, emphasising the spectacular diversity that is the motivation for their conservation. The central chapters describe the origins of rain forest communities, the variety of rain forest formations, and their ecology and dynamics. The challenge of explaining the species richness of rain forest communities lies at the heart of ecological theory, and forms a common theme throughout. The book's final section considers historical and current interactions of humans and rain forests. It explores biodiversity conservation as well as livelihood security for the many communities that are dependent on rain forests - inextricable issues that represent urgent priorities for scientists, conservationists, and policy makers.

This book investigates the economic, strategic, and political importance of forests in early modern and modern Europe and shows how struggles over this vital natural resource both shaped and reflected the ideologies and outcomes of France's long revolutionary period. Until the mid-nineteenth century, wood was the principal fuel for cooking and heating and the primary material for manufacturing worldwide and comprised every imaginable element of industrial, domestic, military, and maritime activity. Forests also provided essential pasturage. These multifaceted values made forests the subject of ongoing battles for control between the crown, landowning elites, and peasantry, for whom liberty meant preserving their rights to woodland commons. Focusing on Franche-Comte, France's easternmost province, the book explores the fiercely contested development of state-centered conservation and management from 1669 to 1848. In emphasizing the environmental underpinnings of France's seismic sociopolitical upheavals, it appeals to readers interested in revolution, rural life, and common-pool-resource governance.

A pioneering scientist writes of the fascinating ecological and pharmaceutical properties of trees, and how mother trees nourish younger trees and help them defend themselves - the inspiration for the documentary Call of the Forest: The Forgotten Wisdom of Trees Renowned scientist Diana Beresford-Kroeger presents an unforgettable and highly original work of natural history with The Global Forest. She explores the fascinating and largely untapped ecological and pharmaceutical properties of trees: leaves that can comb the air of particulate pollution, fatty acids in the nuts of hickory and walnut trees that promote brain development, the compound in the water ash that helps prevent cancer, aerosols in pine trees that calm nerves. In precise, imaginative, and poetic prose, she describes the complexity and beauty of forests, as well as the environmental dangers they face. The author's indisputable passion for her subject matter will inspire readers to look at trees, and at their own connection to the natural world, with newfound awe.

Forests provide vital ecosystem services crucial to human well-being and sustainable development, and have an important role to play in achieving the seventeen Sustainable Development Goals (SDGs) of the United Nations 2030 Agenda. Little attention, however, has yet focused on how efforts to achieve the SDGs will impact forests and forest-related livelihoods, and how these impacts may, in turn, enhance or undermine the contributions of forests to climate and development. This book discusses the conditions that influence how SDGs are implemented and prioritised, and provides a systematic, multidisciplinary global assessment of interlinkages among the SDGs and their targets, increasing understanding of potential synergies and unavoidable trade-offs between goals. Ideal for academic researchers, students and decision-makers interested in sustainable development in the context of forests, this book will provide invaluable knowledge for efforts undertaken to reach the SDGs. This title is available as Open Access via Cambridge Core.
