Available in PDF, EPUB and Kindle. Book excerpt: The authors recount twelve millennia of history along the lower San Juan River, much of it the story of mostly unsuccessful human attempts to make a living from the river's arid and fickle environment. From the Anasazi to government dam builders, from Navajo to Mormon herders and farmers, from scientific explorers to busted miners, the San Juan has attracted more attention and fueled more hopes than such a remote, unpromising, and muddy stream would seem to merit.

Download or read book Flood Pulsing in Wetlands written by Beth A. Middleton and published by John Wiley & Sons. This book was released on 2002-10-15 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: The latest cutting-edge research on flood pulsing and wetland restoration in North America Presenting the latest research from leaders in the field of restoration ecology, Flood Pulsing in Wetlands reflects the current movement to incorporate flood pulsing into wetland restoration efforts. Emphasizing how integral flood pulsing is to successful wetland restoration, the book's contributors provide descriptions of restoration projects across North America in which flood pulsing has been primarily used to restore beneficial hydrodynamic conditions to floodplain areas, and improve or save vegetation, wildlife, and terrain. Detailing the importance and applicability of recreating flood-pulsed conditions on floodplains for successful restoration, the first chapter introduces the concept of flood pulse and its unique role in wetland restoration. The following chapters detail the strategies and results of individual projects and the impact flood pulsing had on the projects' overall goals. Case studies detail the history of each region, such as the Southwest, including the Sonoran Desert communities and the Middle Rio Grande; the Missouri River in Montana; the Illinois River Valley; and the Southeast, including Brushy Lake, Arkansas. Also documented is the most famous case of flood pulsing used in the restoration of an entire landscape, the Kissimmee River project. Approaches used to restore specific plant and animal populations, the unique ecological concerns of each region, and the future outlook for each area are fully described. Extensive bibliographies for each chapter make Flood Pulsing in Wetlands: Restoring the Natural Hydrological Balance the essential reference for restoration ecologists, consultants in wetland restoration, government and restoration agency employees, land managers, ecologists, foresters, and geologists.
Download or read book Ecology and Conservation of the San Pedro River written by Juliet C. Stromberg and published by University of Arizona Press. This book was released on 2009 with total page 552 pages. Available in PDF, EPUB and Kindle. Book excerpt: contributors - biologists, ecologists, geomorphologists, historians, hydrologists, lawyers, and political scientists - weave together threads from their diverse perspectives to reveal the processes that shape the past, present, and future of the San Pedro's riparian and aquatic ecosystems. They review the biological communities of the San Pedro and the stream hydrology and geomorphology that affects its riparian biota. They then look at conservation and management challenges along three sections of the San Pedro, from its headwaters in Mexico in its confluence with the Gila River, describing legal and policy issues and their interface with science; activities related to mitigation, conservation, and restoration; and a prognosis of the potential for sustaining the basin's riparian system." "Complemented by a foreword written by James Shuttleworth, these chapters demonstrate the complexity of the San Pedro's ecological and hydrological conditions, showing that there are no easy --
Download or read book Riparian Ecosystem Recovery in Arid Lands written by Mark K. Briggs and published by University of Arizona Press. This book was released on 2023-03-07 with total page 177 pages. Available in PDF, EPUB and Kindle. Book excerpt: Riparian ecosystems are declining throughout the southwestern United States, where many have disappeared completely; yet progress toward checking their decline has been marginal, and the results of only a few recovery projects have been evaluated. In this guidebook, Mark K. Briggs has filled this gap in riparian conservation literature. Based on his experiences gleaned from evaluating the results of many riparian rehabilitation projects, Briggs presents these results in a manner that biologists, hydrologists, government planners, resource managers, and other concerned citizens can immediately apply toward developing site-specific recovery strategies. The book opens with a review of watershed characteristics and an examination of drainage systems, then proceeds to determining the causes of riparian decline. It introduces five factors that have a significant effect on the results of riparian rehabilitation--natural regeneration, water availability, channel stability, direct impacts such as livestock grazing and recreational activities, and soil salinity--and offers case studies that demonstrate how revegetation has been used both effectively and ineffectively. It also discusses strategies other than revegetation that may be effective in improving the ecological condition of a site. Many of the strategies presented are also relevant to nonarid climates and to urban areas. By emphasizing evaluation of riparian ecosystems, so that the causes of degradation can be understood, and by offering general approaches that can be tailored to specific situations, Riparian Ecosystem Recovery in Arid Lands takes a holistic approach to riparian recovery that will enable users to better judge whether recovery expenditures are likely to produce desired results. An unprecedented work, it will substantially add to efforts across the Southwest and elsewhere to restore these unique and priceless ecosystems.
