Book Description
Woody wetlands constitute a relatively small but extremely important part of the landscape in the southwestern United States. These riparian habitats support more than one-third of the regionÕs vascular plant species, are home to a variety of wildlife, and provide essential havens for dozens of migratory animals. Because of their limited size and disproportionately high biological value, the goal of protecting wetland environments frequently takes priority over nearly all other habitat types. In The Ribbon of Green, hydrologists Robert H. Webb, and Stanley A. Leake and botanist Raymond M. Turner examine the factors that affect the stability of woody riparian vegetation, one of the largest components of riparian areas. Such factors include the diversion of surface water, flood control, and the excessive use of groundwater. Combining repeat photography with historical context and information on species composition, they document more than 140 years of change. Contrary to the common assumption of widespread losses of this type of ecosystem, the authors show that vegetation has increased on many river reaches as a result of flood control, favorable climatic conditions, and large winter floods that encourage ecosystem disturbance, germination, and the establishment of species in newly generated openings. Bringing well-documented and accessible insights to the ecological study of wetlands, this book will influence our perception of change in riparian ecosystems and how riparian restoration is practiced in the Southwest, and it will serve as an important reference in courses on plant ecology, riparian ecology, and ecosystem management.

Book Description
The Clean Water Act (CWA) requires that wetlands be protected from degradation because of their important ecological functions including maintenance of high water quality and provision of fish and wildlife habitat. However, this protection generally does not encompass riparian areasâ€"the lands bordering rivers and lakesâ€"even though they often provide the same functions as wetlands. Growing recognition of the similarities in wetland and riparian area functioning and the differences in their legal protection led the NRC in 1999 to undertake a study of riparian areas, which has culminated in Riparian Areas: Functioning and Strategies for Management. The report is intended to heighten awareness of riparian areas commensurate with their ecological and societal values. The primary conclusion is that, because riparian areas perform a disproportionate number of biological and physical functions on a unit area basis, restoration of riparian functions along America's waterbodies should be a national goal.

Book Description
Aldo Leopold, father of the "land ethic," once said, "The time has come for science to busy itself with the earth itself. The first step is to reconstruct a sample of what we had to begin with." The concept he expressedâ€"restorationâ€"is defined in this comprehensive new volume that examines the prospects for repairing the damage society has done to the nation's aquatic resources: lakes, rivers and streams, and wetlands. Restoration of Aquatic Ecosystems outlines a national strategy for aquatic restoration, with practical recommendations, and features case studies of aquatic restoration activities around the country. The committee examines: Key concepts and techniques used in restoration. Common factors in successful restoration efforts. Threats to the health of the nation's aquatic ecosystems. Approaches to evaluation before, during, and after a restoration project. The emerging specialties of restoration and landscape ecology.

Book Description
Recognizing the importance of wetland protection, the Bush administration in 1988 endorsed the goal of "no net loss" of wetlands. Specifically, it directed that filling of wetlands should be avoided, and minimized when it cannot be avoided. When filling is permitted, compensatory mitigation must be undertaken; that is, wetlands must be restored, created, enhanced, and, in exceptional cases, preserved, to replace the permitted loss of wetland area and function, such as water quality improvement within the watershed. After more than a dozen years, the national commitment to "no net loss" of wetlands has been evaluated. This new book explores the adequacy of science and technology for replacing wetland function and the effectiveness of the federal program of compensatory mitigation in accomplishing the nation's goal of clean water. It examines the regulatory framework for permitting wetland filling and requiring mitigation, compares the mitigation institutions that are in use, and addresses the problems that agencies face in ensuring sustainability of mitigated wetlands over the long term. Gleaning lessons from the mixed results of mitigation efforts to date, the book offers 10 practical guidelines for establishing and monitoring mitigated wetlands. It also recommends that federal, state, and local agencies undertake specific institutional reforms. This book will be important to anyone seeking a comprehensive understanding of the "no net loss" issue: policy makers, regulators, environmental scientists, educators, and wetland advocates.

Book Description
Improperly constructed or maintained roads near riparian and wetland areas may degrade these valuable sites. Degradation affects many aspects of the riparian and wetland ecosystems. This field guide presents information in a practical, user friendly format to help resource managers and professionals. Well-documented evaluation and monitoring strategies are critical in riparian road restoration projects. Learning from mistakes as well as successes helps to improve and protect valuable riparian and wetland sites. This two-volume field guide covers the management and techniques for riparian restoration near roads. The field guides cover the following topics: (1) riparian area considerations, (2) monitoring, (3) planning projects, (4) laws and regulations, and (5) techniques to use in the field.

Book Description
"Wetlands" has become a hot word in the current environmental debate. But what does it signify? In 1991, proposed changes in the legal definities of wetlands stirred controversy and focused attention on the scientific and economic aspects of their management. This volume explores how to define wetlands. The committee--whose members were drawn from academia, government, business, and the environmental community--builds a rational, scientific basis for delineating wetlands in the landscape and offers recommendations for further action. Wetlands also discusses the diverse hydrological and ecological functions of wetlands, and makes recommendations concerning so-called controversial areas such as permafrost wetlands, riparian ecosystems, irregularly flooded sites, and agricultural wetlands. It presents criteria for identifying wetlands and explores the problems of applying those criteria when there are seasonal changes in water levels. This comprehensive and practical volume will be of interest to environmental scientists and advocates, hydrologists, policymakers, regulators, faculty, researchers, and students of environmental studies.

Book Description
Restoring Ecological Health to Your Land is the first practical guidebook to give restorationists and would-be restorationists with little or no scientific training or background the “how to” information and knowledge they need to plan and implement ecological restoration activities. The book sets forth a step-by-step process for developing, implementing, monitoring, and refining on-the-ground restoration projects that is applicable to a wide range of landscapes and ecosystems. The first part of the book introduces the process of ecological restoration in simple, easily understood language through specific examples drawn from the authors’ experience restoring their own lands in southern and central Wisconsin. It offers systematic, step-by-step strategies along with inspiration and benchmark experiences. The book’s second half shows how that same “thinking” and “doing” can be applied to North America’s major ecosystems and landscapes in any condition or scale. No other ecological restoration book leads by example and first-hand experience likethis one. The authors encourage readers to champion restoration of ecosystems close to where they live . . . at home, on farms and ranches, in parks and preserves. It provides an essential bridge for people from all walks of life and all levels of experience—from land trust member property stewards to agency personnel responsible for restoring lands in their care—and represents a unique and important contribution to the literature on restoration.

Book Description
Let the Water Do the Work is an important contribution to riparian restoration. By "thinking like a creek," one can harness the regenerative power of floods to reshape stream banks and rebuild floodplains along gullied stream channels. Induced Meandering is an artful blend of the natural sciences - geomorphology, hydrology and ecology - which govern channel forming processes. Induced Meandering directly challenges the dominant paradigm of river and creek stabilization by promoting the intentional erosion of selected banks while fostering deposition of eroded materials on an evolving floodplain. The river self-heals as the growth of native riparian vegetation accelerates the meandering process. Not all stream channel types are appropriate for Induced Meandering, yet the Induced Meandering philosophy of "going with the flow" can inform all stream restoration projects. Induced meandering strives to understand rivers as timeless entities governed by immutable rules serving their watersheds, setting their own timetables, and coping with their own realities as they carry mountains grain by grain to the sea. Anyone with an interest in natural resource management in these uncertain times should read this book and put these ideas to work.
