Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Colorado River Basin Water Management written by National Research Council and published by National Academies Press. This book was released on 2007-06-30 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent studies of past climate and streamflow conditions have broadened understanding of long-term water availability in the Colorado River, revealing many periods when streamflow was lower than at any time in the past 100 years of recorded flows. That information, along with two important trends-a rapid increase in urban populations in the West and significant climate warming in the region-will require that water managers prepare for possible reductions in water supplies that cannot be fully averted through traditional means. Colorado River Basin Water Management assesses existing scientific information, including temperature and streamflow records, tree-ring based reconstructions, and climate model projections, and how it relates to Colorado River water supplies and demands, water management, and drought preparedness. The book concludes that successful adjustments to new conditions will entail strong and sustained cooperation among the seven Colorado River basin states and recommends conducting a comprehensive basinwide study of urban water practices that can be used to help improve planning for future droughts and water shortages.

Book excerpt: A fascinating investigation into the miraculous world of birds and the powerful—and surprising—ways they enrich our lives and sustain the planet Our relationship to birds is different from our relationship to any other wild creatures. They are everywhere and we love to watch them, listen to them, keep them as pets, wear their feathers, even converse with them. Birds, Jim Robbins posits, are our most vital connection to nature. They compel us to look to the skies, literally and metaphorically; draw us out into nature to seek their beauty; and let us experience vicariously what it is like to be weightless. Birds have helped us in many of our endeavors: learning to fly, providing clothing and food, and helping us better understand the human brain and body. And they even have much to teach us about being human. A natural storyteller, Robbins illuminates how qualities unique to birds make them invaluable to humankind—from the Australian brush turkey, which helped scientists discover how dinosaurs first flew, to the eagles in Washington D.C. that rehabilitated the troubled teenagers placed in charge of their care. From the “good luck” ravens in England to the superb lyrebird, whose song is so sophisticated it can mimic koalas, crying babies and chainsaws, Robbins shows our close relationship with birds, the ways in which they are imperiled and how we must fight to save them for the sake of both the planet and humankind. Jim Robbins has written for the New York Times for more than thirty-five years, as well as numerous other magazines including Audubon, Condé Nast Traveler, BBC Future, Smithsonian and Vanity Fair. He is the author of several books including The Man Who Planted Trees and Last Refuge: The Environmental Showdown in the American West. ‘Fittingly for a work about birds and what they can teach us, The Wonder of Birds soars beyond its putative subject into realms once regarded as mystical.’ —Fiona Capp, The Sydney Morning Herald ‘A must-read, conveying much necessary information in easily accessible form and awakening one’s consciousness to what might otherwise be taken for granted ... The Wonder of Birds reads like the story of a kid let loose in a candy store and given free rein to sample. That is one of its strengths: the convert’s view gives wide appeal to those who might never have known birds well.’ —Bernd Heinrich, Wall Street Journal

Download or read book Southwestern Desert Resources written by William L. Halvorson and published by University of Arizona Press. This book was released on 2023-01-17 with total page 375 pages. Available in PDF, EPUB and Kindle. Book excerpt: The southwestern deserts stretch from southeastern California to west Texas and then south to central Mexico. The landscape of this region is known as basin and range topography featuring to “sky islands” of forest rising from the desert lowlands which creates a uniquely diverse ecology. The region is further complicated by an international border, where governments have caused difficulties for many animal populations. This book puts a spotlight on individual research projects which are specific examples of work being done in the area and when they are all brought together, to shed a general light of understanding the biological and cultural resources of this vast region so that those same resources can be managed as effectively and efficiently as possible. The intent is to show that collaborative efforts among federal, state agency, university, and private sector researchers working with land managers, provides better science and better management than when scientists and land managers work independently.
