Northern Michigan is undergoing unprecedented changes in land use, climate, resource extraction, and species distributions. For the last hundred years, the University of Michigan Biological Station has monitored these environmental transformations. Stretching 10,000 acres along Burt and Douglas Lakes in the northern Lower Peninsula and 3,200 acres on Sugar Island near Sault Ste. Marie, Michigan, the station has played host to nearly 10,000 students and a steady stream of top scientists in the fields of biology, ecology, geology, archeology, and climatology.

The Changing Environment of Northern Michigan collects essays by some of these scientists, who lead readers on virtual field trips exploring the history of people and science at the station itself, the relations of indigenous people to the land, the geophysical history of the region, characteristics of terrestrial and aquatic ecosystems, key groups of organisms and their relations to local habitats, and perspectives on critical environmental challenges of today and their effects on the region. Accompanying the chapters are color illustrations and photographs that bring the station's pristine setting to life.

Like the station itself, the book provides a solid background for better appreciating the relationships among living and nonliving parts of northern Michigan, for anyone interested in exploring the region's forests, fields, and wetlands; wading or paddling down its rivers; or swimming or floating across its lakes.

Over the past decade, a sea change has occurred in the field of forestry. A vastly increased understanding of how ecological systems function has transformed the science from one focused on simplifying systems, producing wood, and managing at the stand-level to one concerned with understanding and managing complexity, providing a wide range of ecological goods and services, and managing across broad landscapes.

Creating a Forestry for the 21st Century is an authoritative and multidisciplinary examination of the current state of forestry and its relation to the emergent field of ecosystem management. Drawing upon the expertise of top professionals in the field, it provides an up-to-date synthesis of principles of ecosystem management and their implications for forest policy. Leading scientists, including Malcolm Hunter, Jr., Bruce G. Marcot, James K. Agee, Thomas R. Crow, Robert J. Naiman, John C. Gordon, R.W. Behan, Steven L. Yaffee, and many others examine topics that are central to the future of forestry:

• new understandings of ecological processes and principles, from stand structure and function to disturbance processes and the movement of organisms across landscapes
• challenges to long-held assumptions: the rationale for clearcutting, the wisdom of short rotations, the exclusion of fire
• traditional tools in light of expanded goals for forest landscapes
• managing at larger spatial scales, including practical information and ideas for managing large landscapes over long time periods
• the economic, organizational, and political issues that are critical to implementing successful ecosystem management and developing institutions to transform knowledge into action

Featuring a 16-page center section with color photographs that illustrate some of the best on-the-ground examples of ecosystem management from around the world, Creating a Forestry for the 21st Century is the definitive text on managing ecosystems. It provides a compelling case for thinking creatively beyond the bounds of traditional forest resource management, and will be essential reading for students; scientists working in state, federal, and private research institutions; public and private forest managers; staff members of environmental/conservation organizations; and policymakers.

The discipline of silviculture is at a crossroads. Silviculturists are under increasing pressure to develop practices that sustain the full function and dynamics of forested ecosystems and maintain ecosystem diversity and resilience while still providing needed wood products. A Critique of Silviculture offers a penetrating look at the current state of the field and provides suggestions for its future development.

The book includes an overview of the historical developments of silvicultural techniques and describes how these developments are best understood in their contemporary philosophical, social, and ecological contexts. It also explains how the traditional strengths of silviculture are becoming limitations as society demands a varied set of benefits from forests and as we learn more about the importance of diversity on ecosystem functions and processes.

The authors go on to explain how other fields, specifically ecology and complexity science, have developed in attempts to understand the diversity of nature and the variability and heterogeneity of ecosystems. The authors suggest that ideas and approaches from these fields could offer a road map to a new philosophical and practical approach that endorses managing forests as complex adaptive systems.

A Critique of Silviculture bridges a gap between silviculture and ecology that has long hindered the adoption of new ideas. It breaks the mold of disciplinary thinking by directly linking new ideas and findings in ecology and complexity science to the field of silviculture. This is a critically important book that is essential reading for anyone involved with forest ecology, forestry, silviculture, or the management of forested ecosystems.

Can land degraded by centuries of agriculture be restored to something approaching its original productivity and diversity? This book tells the story of fifty years of restoration and management of the forested landscape of the Savannah River Site, a 310-square-mile tract of land in the coastal plain of South Carolina that has been closed to the public for more than five decades.

Ecology and Management of a Forested Landscape presents for the first time a complete synthesis and summary of information on the Savannah River Site, providing a detailed portrait of the plant and animal populations and communities on the site and the effects on them of fifty years of management practices. Contributors offer thirty-two chapters that describe the site's history, land management, physical environment, plant and animal communities, endangered species, and game species. Extensively illustrated with photos, maps, charts, and tables, the book provides a comprehensive overview of the forest management practices that can support long-term forest recovery and restoration of native habitats. It represents for natural resource managers a detailed case study in long-term land management, and provides scientists with an in-depth analysis of the natural history and physical and biological characteristics of a southeastern forested landscape.

Scientists tell us that climate change is upon us and the physical world is changing quickly with important implications for biodiversity and human well-being. Forests cover vast regions of the globe and serve as a first line of defense against the worst effects of climate change, but only if we keep them healthy and resilient.

Forests in Our Changing World tells us how to do that. Authors Joe Landsberg and Richard Waring present an overview of forests around the globe, describing basic precepts of forest ecology and physiology and how forests will change as earth’s climate warms. Drawing on years of research and teaching, they discuss the values and uses of both natural and plantation-based forests. In easy-to-understand terms, they describe the ecosystem services forests provide, such as clean water and wildlife habitat, present economic concepts important to the management and policy decisions that affect forests, and introduce the use of growth-and-yield models and remote-sensing technology that provide the data behind those decisions.

This book is a useful guide for undergraduates as well as managers, administrators, and policy makers in environmental organizations and government agencies looking for a clear overview of basic forest processes and pragmatic suggestions for protecting the health of forests.

More Tree Talk is an insightful and compelling look at the human dimension of the challenges facing forestry. First published in 1981, Tree Talk was widely hailed as the most even-handed and well-written introduction to forestry issues available. More Tree Talk is an entirely revised edition of that classic volume that brings the book up-to-date with the current situation.

Like the original, More Tree Talk features a running narrative punctuated by individual portraits that personalize the issues. It translates political and academic aspects of forestry into human terms, focusing on those whose lives and livelihoods depend on the outcome of the debates currently raging -- old-time woodsmen, loggers, naturalists, restoration workers, timber company executives.

Ray Raphael explores the new forestry practices, theories, and controversies that have emerged in the past decade as he addresses problems of a declining resource base and increasing regulatory policies. He examines the impact of ecological and economic concerns on rural communities, and considers the possibility of large structural changes in the ways in which timber companies operate. Throughout, he emphasizes that without an understanding of the economic and political factors that interfere with good forest management, all the scientific knowledge -- and all the best intentions of on-site workers -- will come to no avail.

Not by Timber Alone presents the findings of the Harvard Institute for International Development study, commissioned by the International Tropical Timber Organization, that examined the economic value of tropical hardwood forests as productive living systems and the potential for their multiple use management.

Developed by the pioneering landscape design firm of Andropogon Associates, world-renowned for their innovative approach to integrating environmental protection and restoration with landscape architecture and design, The Once and Future Forest is a guidebook for restoring and managing natural landscapes. Focusing on remnant forest systems, it describes methods of restoring and linking forest fragments to recreate a whole landscape fabric.

The book begins by explaining the history and current situation of forest ecosystems in the eastern United States. Following that is an in-depth examination of the restoration process, with thorough descriptions of ecological strategies for landscape management along with specific examples of how those strategies have been implemented in various sites around the country. The final section provides hands-on information about the many specific details that must be considered when initiating and implementing a restoration program. All aspects of the restoration process are considered, including: Water -- opportunities for increasing infiltration, reducing pollutants, promoting habitat values Ground -- methods of protecting existing vegetation, removing fill, rebuilding soils Plants -- strategies and procedures for planting, maintenance, propagation Wildlife -- guidelines for preserving wildlife resources, management techniques to favor selected specie.

The Once and Future Forest presents a comprehensive approach to assessing sites, detailed guidelines for determining management goals, and a thorough overview of appropriate management and restoration techniques. It is an important guide for professional planners and landscape architects, government agency personnel at all levels, land managers, scientists involved in restoration work, and citizen activists who wish to do something constructive about our deteriorating forest patches.

Positive Impact Forestry is a primer for private woodland owners and their managers on managing their land and forests to protect both ecological and economic vitality. Moving beyond the concept of "low impact forestry," Thom McEvoy brings together the latest scientific understanding and insights to describe an approach to managing forests that meets the needs of landowners while at the same time maintaining the integrity of forest ecosystems. "Positive impact forestry" emphasizes forestry's potential to achieve sustainable benefits both now and into the future, with long-term investment superseding short-term gain, and the needs of families -- especially future generations -- exceeding those of individuals.

Thom McEvoy offers a thorough discussion of silvicultural basics, synthesizing and explaining the current state of forestry science on topics such as forest soils, tree roots, form and function in trees, and the effects of different harvesting methods on trees, soil organisms, and sites. He also offers invaluable advice on financial, legal, and management issues, ranging from finding the right forestry professionals to managing for products other than timber to passing forest lands and management legacies on to future generations.

Positive Impact Forestry helps readers understand the impacts of deliberate human activities on forests and offers viable strategies that provide benefits without damaging ecosystems. It speaks directly to private forest owners and their advisers and represents an innovative guide for anyone concerned with protecting forest ecosystems, timber production, land management, and the long-term health of forests.

Named the "Best Forestry Book for 2004" by the National Woodlands Owners Association

Evidence is mounting that redwood forests, like many other ecosystems, cannot survive as small, isolated fragments in human-altered landscapes. Such fragments lose their diversity over time and, in the case of redwoods, may even lose the ability to grow new, giant trees.

The Redwood Forest, written in support of Save-the-Redwood League's master plan, provides scientific guidance for saving the redwood forest by bringing together in a single volume the latest insights from conservation biology along with new information from data-gathering techniques such as GIS and remote sensing. It presents the most current findings on the geologic and cultural history, natural history, ecology, management, and conservation of the flora and fauna of the redwood ecosystem. Leading experts -- including Todd Dawson, Bill Libby, John Sawyer, Steve Sillett, Dale Thornburgh, Hartwell Welch, and many others -- offer a comprehensive account of the redwoods ecosystem, with specific chapters examining:

• the history of the redwood lineage, from the Triassic Period to the present, along with the recent history of redwoods conservation
• life history, architecture, genetics, environmental relations, and disturbance regimes of redwoods
• terrestrial flora and fauna, communities, and ecosystems
• aquatic ecosystems
• landscape-scale conservation planning
• management alternatives relating to forestry, restoration, and recreation.

The Redwood Forest offers a case study for ecosystem-level conservation and gives conservation organizations the information, technical tools, and broad perspective they need to evaluate redwood sites and landscapes for conservation. It contains the latest information from ground-breaking research on such topics as redwood canopy communities, the role of fog in sustaining redwood forests, and the function of redwood burls. It also presents sobering lessons from current research on the effects of forestry activities on the sensitive faunas of redwood forests and streams.

The key to perpetuating the redwood forest is understanding how it functions; this book represents an important step in establishing such an understanding. It presents a significant body of knowledge in a single volume, and will be a vital resource for conservation scientists, land use planners, policymakers, and anyone involved with conservation of redwoods and other forests.

Recent advances in remote-sensing technology and the processing of remote-sensing data through geographic information systems (GIS) present ecologists and resource managers with a tremendously valuable tool -- but only if they are able to understand its capabilities and capture its potential.

Remote Sensing and GIS in Ecosystem Management identifies and articulates current and emerging information needs of those involved with the management of forest ecosystems. It explores the potential of remote-sensing/GIS technologies to address those needs, examining:

• the need for landscape-scale analysis to support forest ecosystem research and management
• current challenges in the development of remote-sensing/GIS applications
• case studies of different forest regions in the United States
• the potential for further development or declassification of military and aerospace remote-sensing/GIS technologies

As well as providing important information for ecologists and resource managers, the book will serve as a valuable resource for legislative and judicial policymakers who do not have a technical background in either remote sensing or resource management but who are nonetheless called upon to make decisions regarding the protection and management of forest ecosystems.

Salvage logging—removing trees from a forested area in the wake of a catastrophic event such as a wildfire or hurricane—is highly controversial. Policymakers and those with an economic interest in harvesting trees typically argue that damaged areas should be logged so as to avoid “wasting” resources, while many forest ecologists contend that removing trees following a disturbance is harmful to a variety of forest species and can interfere with the natural process of ecosystem recovery.
 
Salvage Logging and Its Ecological Consequences brings together three leading experts on forest ecology to explore a wide range of issues surrounding the practice of salvage logging. They gather and synthesize the latest research and information about its economic and ecological costs and benefits, and consider the impacts of salvage logging on ecosystem processes and biodiversity. The book examines
 
• what salvage logging is and why it is controversial
• natural and human disturbance regimes in forested ecosystems
• differences between salvage harvesting and traditional timber harvesting
• scientifically documented ecological impacts of salvage operations
• the importance of land management objectives in determining appropriate post-disturbance interventions
 
Brief case studies from around the world highlight a variety of projects, including operations that have followed wildfires, storms, volcanic eruptions, and insect infestations. In the final chapter, the authors discuss policy management implications and offer prescriptions for mitigating the impacts of future salvage harvesting efforts.
  
Salvage Logging and Its Ecological Consequences is a “must-read” volume for policymakers, students, academics, practitioners, and professionals involved in all aspects of forest management, natural resource planning, and forest conservation.

Though seasonally dry tropical forests are equally as important to global biodiversity as tropical rainforests, and are one of the most representative and highly endangered ecosystems in Latin America, knowledge about them remains limited because of the relative paucity of attention paid to them by scientists and researchers and a lack of published information on the subject.
 
Seasonally Dry Tropical Forests seeks to address this shortcoming by bringing together a range of experts in diverse fields including biology, ecology, biogeography, and biogeochemistry, to review, synthesize, and explain the current state of our collective knowledge on the ecology and conservation of seasonally dry tropical forests.
 
The book offers a synthetic and cross-disciplinary review of recent work with an expansive scope, including sections on distribution, diversity, ecosystem function, and human impacts. Throughout, contributors emphasize conservation issues, particularly emerging threats and promising solutions, with key chapters on climate change, fragmentation, restoration, ecosystem services, and sustainable use.
 
Seasonally dry tropical forests are extremely rich in biodiversity, and are seriously threatened. They represent scientific terrain that is poorly explored, and there is an urgent need for increased understanding of the system's basic ecology. Seasonally Dry Tropical Forests represents an important step in bringing together the most current scientific information about this vital ecosystem and disseminating it to the scientific and conservation communities.

How long should a leaf live? When should blueberries ripen? And what should a clever moose eat? Questions like these may seem simple or downright strange—yet they form the backbone of natural history, a discipline that fostered some of our most important scientific theories, from natural selection to glaciation. Through careful, patient observations of the organisms that live in an area, their distributions, and how they interact with other species, we gain a more complete picture of the world around us, and our place in it.

In What Should a Clever Moose Eat?, John Pastor explores the natural history of the North Woods, an immense and complex forest that stretches from the western shore of Lake Superior to the far coast of Newfoundland. The North Woods is one of the most ecologically and geologically interesting places on the planet, with a host of natural history questions arising from each spruce or sugar maple. From the geological history of the region to the shapes of leaves and the relationship between aspens, caterpillars, and predators, Pastor delves into a captivating range of topics as diverse as the North Woods themselves. Through his meticulous observations of the natural world, scientists and nonscientists alike learn to ask natural history questions and form their own theories, gaining a greater understanding of and love for the North Woods—and other natural places precious to them.

In the tradition of Charles Darwin and Henry David Thoreau, John Pastor is a joyful observer of nature who makes sharp connections and moves deftly from observation to theory. Take a walk in John Pastor's North Woods—you'll come away with a new appreciation for details, for the game trails, beaver ponds, and patterns of growth around you, and won't look at the natural world in the same way again.
