Riparian Areas


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.

The Ribbon of Green


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.




Multiple Stressors in River Ecosystems


Book Description

Multiple Stressors in River Ecosystems: Status, Impacts and Prospects for the Future provides a comprehensive and current overview on the topic as written by leading river scientists who discuss the relevance of co-occurring stressors for river ecosystems. River ecosystems are subject to multiple stressors that threaten their ecological status and the ecosystem services they provide. This book updates the reader's knowledge on the response and management of river ecosystems to multi-stress situations occurring under global change. Detailing the risk for biodiversity and functioning in a case-study approach, it provides insight into methodological issues, also including the socioeconomic implications. - Presents a case study approach and geographic description on the relevance of multiple stressors on river ecosystems in different biomes - Gives a uniquely integrated perspective on different stressors, including their interactions and joint effects, as opposed to the traditional one-by-one approach - Compiles state-of-the-art methods and technologies in monitoring, modeling and analyzing river ecosystems under multiple stress conditions




California Riparian Systems


Book Description

This volume presents 135 of the papers presented at the 1981 California Riparian Systems Conference. The papers address all aspects of riparian systems: habitat, wildlife, land management, land use policy planning, conservation and water resource management.




Ecological Significance of River Ecosystems


Book Description

Ecological Significance of Riparian Ecosystems: Challenges and Management Strategies examines the current issues related to river ecosystems, their environmental importance, pollution issues and potential management strategies. The book is divided into 4 key themes: Basics of river ecosystem, Natural phenomenon of river ecosystem, Human-induced problems of river ecosystem, and Management measures for the river ecosystem. Through these four themes, the contributors present both practical and theoretical aspects of river ecosystem in changing climate. An emphasis has been made on the recent research of climate change and its impact on the river ecosystem. River ecosystems have tremendous potential to store CO2, however, with changing climatic and anthropogenic activities, these habitats are under threat, and river ecosystems are losing the very vital service of storing carbon. Unlike well documented terrestrial biodiversity, the biodiversity in aquatic ecosystems is still unrecognized to some extent. - Presents an understanding of the biogeochemical processes of river ecosystems achieved by food webs and diverse biogeochemical processes - Covers sediment dynamics and nutrient chemistry - hot topics in river ecosystems - Includes environmental pollution issues in river ecosystems from various anthropogenic activities




Riparian Areas of the Southwestern United States


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.




Great Basin Riparian Ecosystems


Book Description

Established by the USDA Forest Service in 1993, the Great Basin Ecosystem Management Project for Restoring and Maintaining Sustainable Riparian Ecosystems is a large-scale research study that uses an interdisciplinary approach to examine the effects of climate change and human disturbance on riparian areas. Structured as a collaborative effort between management and research, the project focuses on understanding the geomorphic, hydrologic, and biotic processes that underlie riparian structure and function and the interrelated responses of those processes to disturbances, both natural and anthropogenic. Great Basin Riparian Ecosystems, edited by Jeanne C. Chambers and Jerry R. Miller, presents the approach used by the researchers to study and understand riparian areas in the Great Basin region. It summarizes the current state of knowledge about those areas and provides insights into the use of the information generated by the project for the restor-ation and management of riparian ecosystems. Because semi-arid ecosystems like the Great Basin are highly sensitive to climate change, the study considered how key processes are affected by past and present climate. Great Basin Riparian Ecosystems also examines the processes over a continuum of temporal and spatial scales. Great Basin Riparian Ecosystems addresses restoration over a variety of scales and integrates work from multiple disciplines, including riparian ecology, paleoecology, geomorphology, and hydrology. While the focus is on the Great Basin, the general approach is widely applicable, as it describes a promising new strategy for developing restoration and management plans, one based on sound principles derived from attention to natural systems.




Long-Term Ecosystem Changes in Riparian Forests


Book Description

This open access book presents and analyzes the results of more than 30 years of long-term ecological research in riparian forest ecosystems with the aim of casting light on changes in the dynamics of riparian forests over time. The research, focusing on the Ooyamazawa riparian forest, one of the remaining old-growth forests in Japan, has yielded a number of interesting outcomes. First, it shows that large-scale disturbances afford various trees opportunities for regeneration and are thus the driving force for the coexistence of canopy trees in riparian forests. Second, it identifies changes in reproductive patterns, highlighting that seed production has in fact quantitatively increased over the past two decades. Third, it describes the decline in forest floor vegetation caused by deer grazing and reveals how this decline has affected bird and insect populations. The book illustrates the interconnectedness of phenomena within an ecosystem and the resultant potential for cascade effects and also stresses the need for long-term ecological studies of climate change impacts on forests. It will be of interest to both professionals and academics in the field of forest science.
