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
Taken from the proceedings of the Second International Symposium on Regulated Streams, these essays cover problems of river regulation, considering both the theoretical implications and the practical effects of these measures. International in scope, this collection will provide new insight into the topic for freshwater biologists and others concerned with the research and planning of water power projects.

Book Description
Riparian Areas of the Southwestern United States: Hydrology, Ecology, and Management provides hydrologists, watershed managers, land-use planners, educators, policymakers, and non-governmental organizations with a comprehensive account of the multiple benefits and conflicts arising from the uniquely structured ecosystems of arid and semi-arid regions. The text describes the inhabitants of southwestern riparian ecosystems and addresses the research, planning, and management concerns for these fragile ecosystems in relation to the impacts of water and sediment flows, livestock grazing, and other human activities, and the maintenance of key wildlife and fish habitats.

Book Description
Riparian Landscapes examines the ecological systems of streamside and floodplain areas from the perspective of landscape ecology. The specific spatial pattern of riparian vegetation is seen as a result of, and a control on, the ecological, geomorphological, and hydrological processes that operate along rivers. Riparian structures are controlled by the spatial dynamics of channels, flooding and soil moisture. These dynamics are part of integrated cascades of water, sediment, nutrients and carbon, to which animal and plant species respond in ways that illuminate community structure and competition. The role of the riparian zone in controlling species distribution and abundance is discussed. Intelligent management of these valuable ecological resources is highlighted. The potential for linking hydrological, geomorphological and ecological simulation models is also explored. This book will be of interest to graduate and professional research workers in environmental science, ecology and physical geography.

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 wetlands and riparian corridors of North Americas Mid-Atlantic Region (MAR) have been under constant and continuing pressure from anthropogenic settlement since before the arrival of the first Europeans on the continent. Disturbances related to human development have impeded the functioning of these ecosystems and reduced the quantity and quality of services they provide to society. An understanding of the detrimental effects of landscape alteration has grown within the past few decades, and in this relatively short period of time, a wealth of research has been compiled on how to reverse these effects through restoration. Floodplains, often heavily settled and modified, have been of particular interest as they provide valuable services such as flood attenuation, soil enrichment, and water storage. Within the context of floodplains, limited attention has been paid to coarse woody debris (CWD) and its role in the ecosystem. Historically, coarse woody debris has been removed from channels and riparian corridors by people for a number of reasons. It is now understood to be a crucial element of ecosystem architecture, and efforts are being made to characterize how CWD dynamics within the landscape affect functioning and service provisioning. Although a body of work on this subject has been produced in the Pacific Northwest of the U.S., there are still many questions that remain to be answered. This research utilizes data collected during rapid field assessments of habitat quality, in conjunction with intensive surveys of debris, to determine how anthropogenic disturbance influences debris abundances and characteristics in floodplain systems. This study was completed in the central Pennsylvania portion of the MAR, an area that, though heavily forested, has received little attention in debris studies. Results demonstrate that the greatest quantities of debris are associated with sites experiencing the least amount of anthropogenic disturbance, and that the debris found at these sites shows greater diversity in size than debris found elsewhere. A moderately-robust mathematical relationship was also established between debris counts and riparian forest basal areas, indicating that this measurement of habitat quality may be the best predictor of debris concentration. These findings have important implications for both ecological integrity and ecosystem service provisioning, and will hopefully enable land managers in the Mid-Atlantic Region to make informed choices regarding debris installations on their properties.
