Available in PDF, EPUB and Kindle. Book excerpt: The Missouri River Ecosystem: Exploring the Prospects for Recovery resulted from a study conducted at the request of the U.S. Environmental Protection Agency and the U.S. Army Corps of Engineers. The nation's longest river, the Missouri River and its floodplain ecosystem experienced substantial environmental and hydrologic changes during the twentieth century. The context of Missouri River dam and reservoir system management is marked by sharp differences between stakeholders regarding the river's proper management regime. The management agencies have been challenged to determine the appropriate balance between these competing interests. This Water Science and Technology Board report reviews the ecological state of the river and floodplain ecosystem, scientific research of the ecosystem, and the prospects for implementing an adaptive management approach, all with a view toward helping move beyond ongoing scientific and other differences. The report notes that continued ecological degradation of the ecosystem is certain unless some portion of pre-settlement river flows and processes were restored. The report also includes recommendations to enhance scientific knowledge through carefully planned and monitored river management actions and the enactment of a Missouri River Protection and Recovery Act.
Download or read book Restoration of Puget Sound Rivers written by David R. Montgomery and published by University of Washington Press. This book was released on 2015-12-31 with total page 516 pages. Available in PDF, EPUB and Kindle. Book excerpt: The recent listing of Pacific salmon under the Endangered Species Act has led to substantial interest in the scientific basis for river restoration in the Pacific Northwest. Millions of dollars in state and federal funding have been programmed for habitat restoration efforts to stem the decline of salmon populations in the region. This volume addresses the need for a solid understanding of fluvial processes and aquatic ecology in order to predict both river and salmonid response to restoration projects. In the Pacific Northwest, as in most regions of the United States, we are still learning about the processes that create habitat and river structure, how those processes influence aquatic ecosystems, and how to gauge the response of river systems to both land-use changes and restoration efforts. River systems are still responding to historic changes, and degraded habitat may not be restored successfully if natural conditions are not well understood, particularly if massive changes in watershed hydrology or other processes are the root cause. These issues faced in the development of regional river restoration programs are by no means unique to the Northwest, and so the initiation of a regional program of river restoration provides an opportunity to evaluate the state of river restoration in general. The eighteen chapters of Restoration of Puget Sound Rivers--presented by the region's experts at a symposium of the Society for Ecological Restoration--examine geological and geomorphological controls on river and stream characteristics and dynamics, biological aspects of river systems in the region, and the application of fluvial geomorphology, civil engineering, riparian ecology, and aquatic ecology in efforts to restore Puget Sound Rivers. This volume will be of interest to geomorphologists, aquatic biologists, civil engineers, planners, and all those interested in the interface of science and policy in addressing one of the fundamental environmental challenges of the twenty-first century.
Download or read book Seedling Ecology and Evolution written by Mary Allessio Leck and published by Cambridge University Press. This book was released on 2008-09-18 with total page 514 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seedlings are highly sensitive to their environment. After seeds, they typically suffer the highest mortality of any life history stage. This book provides a comprehensive exploration of the seedling stage of the plant life cycle. It considers the importance of seedlings in plant communities; environmental factors with special impact on seedlings; the morphological and physiological diversity of seedlings including mycorrhizae; the relationship of the seedling with other life stages; seedling evolution; and seedlings in human altered ecosystems, including deserts, tropical rainforests, and habitat restoration projects. The diversity of seedlings is portrayed by including specialised groups like orchids, bromeliads, and parasitic and carnivorous plants. Discussions of physiology, morphology, evolution and ecology are brought together to focus on how and why seedlings are successful. This important text sets the stage for future research and is valuable to graduate students and researchers in plant ecology, botany, agriculture and conservation.
Download or read book The Floodplain Forests in Europe written by and published by BRILL. This book was released on 2021-10-25 with total page 279 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this volume the condition of floodplain forests and ecological impacts of anthropogenic effects is reviewed. The most important anthropogenic impacts dealt with are as follows: decrease of floodplain forest area in favor of agriculture; watercourse regulation resulting in termination of floods and groundwater table decrease; construction of dams or building of water reservoirs resulting in destruction of floodplain forest areas; interactions between floodplain forests and housing estates; intensive game-management; and fragmentation of floodplain forest ecosystems. The book will serve as background information on forest ecosystems that were markedly influenced in the past, decreased to a minimum level and/or heavily endangered at present. The condition of the following floodplain forests in selected watersheds of Europe is covered: France (the Rhone), Germany (surroundings of Leipzig), Hungary, Slovakia (the Morova and Danube), Czech Republic (the Morova and Dyje), Russia, Poland, Ukraine, Romania (the Danube), Croatia (the Sava and Drava) and Slovenia (Sava).

Download or read book Amazonian Floodplain Forests written by Wolfgang J. Junk and published by Springer Science & Business Media. This book was released on 2010-09-27 with total page 620 pages. Available in PDF, EPUB and Kindle. Book excerpt: Central Amazonian floodplain forests are an unique and endangered ecosystem. The forests grow in areas that are annually flooded by large rivers during mean periods of up to 8 months and at depths of up to 10 m. Despite this severe stress, these forests consist of over 1,000 species and are by far the most species-rich floodplain forests worldwide. The trees show a broad range of morphological, anatomical, physiological, and phenological adaptations that enable them not only to survive the adverse environmental conditions, but also to produce large amounts of biomass when the nutrient levels in water and soils are sufficiently high. This is the case in the floodplains of white-water rivers, which are used for fisheries, agriculture, and cattle-ranching but which also have a high potential for the production of timber and non-timber products, when adequately managed. Latest research on ecophysiology gives insight how tree species adapt to the oscillating flood-pulse focusing on their photosynthesis, respiration, sap flow, biochemistry, phenology, wood and leave anatomy, root morphology and functioning, fruit chemistry, seed germination, seedling establishment, nitrogen fixation and genetic variability. Based on tree ages, lifetime growth rates and net primary production, new concepts are developed to improve the sustainability of traditional forest managements in the background of an integrated natural resource management. This is the first integrative book on the functioning and ecologically oriented use of floodplain forests in the tropics and sub-tropics.It provides fundamental knowledge for scientist, students, foresters and other professionals on their distribution, evolution and phytogeography. “This book is an excellent testimony to the interdisciplinary collaboration of a group of very dedicated scientists to unravel the functioning of the Amazonian Floodplain forests. They have brought together a highly valuable contribution on the distribution, ecology, primary production, ecophysiology, typology, biodiversity, and human use of these forests offering recommendations for sustainable management and future projects in science and development of these unique wetland ecosystems. It lays a solid scientific foundation for wetland ecologists, foresters, environmentalists, wetland managers, and all those interested in sustainable management in the tropics and subtropics.” Brij Gopal, Executive Vice President International Society for Limnology (SIL).

Download or read book Inland Flood Hazards written by Ellen E. Wohl and published by Cambridge University Press. This book was released on 2000-07-03 with total page 520 pages. Available in PDF, EPUB and Kindle. Book excerpt: This edited volume was originally published in 2000 and presents a comprehensive, interdisciplinary review of issues related to inland flood hazards. It addresses physical controls on flooding, flood processes and effects, and responses to flooding, from the perspective of human, aquatic, and riparian communities. Individual chapter authors are recognized experts in their fields who draw on examples and case studies of inland flood hazards from around the world. This volume is unusual among treatments of flood hazards in that it addresses how the non-occurrence of floods, in association with flow regulation and other human manipulation of river systems, may create hazards for aquatic and riparian communities. This book will be a valuable resource for everyone associated with inland flood hazards: professionals in government and industry, and researchers and graduate students in civil engineering, geography, geology, hydrology, hydraulics, and ecology.

Download or read book Ecology and Recovery of Eastern Old Growth Forests written by Andrew M. Barton and published by Island Press. This book was released on 2018-11-08 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: The landscapes of North America, including eastern forests, have been shaped by humans for millennia, through fire, agriculture, hunting, and other means. But the arrival of Europeans on America’s eastern shores several centuries ago ushered in the rapid conversion of forests and woodlands to other land uses. By the twentieth century, it appeared that old-growth forests in the eastern United States were gone, replaced by cities, farms, transportation networks, and second-growth forests. Since that time, however, numerous remnants of eastern old growth have been discovered, meticulously mapped, and studied. Many of these ancient stands retain surprisingly robust complexity and vigor, and forest ecologists are eager to develop strategies for their restoration and for nurturing additional stands of old growth that will foster biological diversity, reduce impacts of climate change, and serve as benchmarks for how natural systems operate. Forest ecologists William Keeton and Andrew Barton bring together a volume that breaks new ground in our understanding of ecological systems and their importance for forest resilience in an age of rapid environmental change. This edited volume covers a broad geographic canvas, from eastern Canada and the Upper Great Lakes states to the deep South. It looks at a wide diversity of ecosystems, including spruce-fir, northern deciduous, southern Appalachian deciduous, southern swamp hardwoods, and longleaf pine. Chapters authored by leading old-growth experts examine topics of contemporary forest ecology including forest structure and dynamics, below-ground soil processes, biological diversity, differences between historical and modern forests, carbon and climate change mitigation, management of old growth, and more. This thoughtful treatise broadly communicates important new discoveries to scientists, land managers, and students and breathes fresh life into the hope for sensible, effective management of old-growth stands in eastern forests.

Download or read book Riparian Areas written by National Research Council and published by National Academies Press. This book was released on 2002-10-10 with total page 449 pages. 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.

Download or read book Nature s Return written by Mark Kinzer and published by Univ of South Carolina Press. This book was released on 2017-06-15 with total page 243 pages. Available in PDF, EPUB and Kindle. Book excerpt: From exploitation to preservation, the complex history of one of the Southeast's most important natural areas and South Carolina's only national park Located at the confluence of the Congaree and Wateree Rivers in central South Carolina, Congaree National Park protects the nation's largest intact expanse of old-growth bottomland hardwood forest. Modern visitors to the park enjoy a pristine landscape that seems ancient and untouched by human hands, but in truth its history is far different. In Nature's Return, Mark Kinzer examines the successive waves of inhabitants, visitors, and landowners of this region by synthesizing information from property and census records, studies of forest succession, tree-ring analyses, slave narratives, and historical news accounts. Established in 1976, Congaree National Park contains within its boundaries nearly twenty-seven thousand acres of protected uplands, floodplains, and swamps. Once exploited by humans for farming, cattle grazing, plantation agriculture, and logging, the park area is now used gently for recreation and conservation. Although the impact of farming, grazing, and logging in the park was far less extensive than in other river swamps across the Southeast, it is still evident to those who know where to look. Cultivated in corn and cotton during the nineteenth century, the land became the site of extensive logging operations soon after the Civil War, a practice that continued intermittently into the late twentieth century. From burning canebrakes to clearing fields and logging trees, inhabitants of the lower Congaree valley have modified the floodplain environment both to ensure their survival and, over time, to generate wealth. In this they behaved no differently than people living along other major rivers in the South Atlantic Coastal Plain. Today Congaree National Park is a forest of vast flats and winding sloughs where champion trees dot the landscape. Indeed its history of human use and conservation make it a valuable laboratory for the study not only of flora and fauna but also of anthropology and modern history. As the impact of human disturbance fades, the Congaree's stature as one of the most important natural areas in the eastern United States only continues to grow.
Download or read book Ecological Restoration of Aquatic and Semi Aquatic Ecosystems in the Netherlands NW Europe written by P.H. Nienhuis and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 239 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work presents the state of the art of aquatic and semi-aquatic ecological restoration projects in The Netherlands. Starting from the conceptual basis of restoration ecology, the successes and failures of hundreds of restoration projects are described. Numerous successful projects are mentioned. In general ecological restoration endeavours greatly benefit from the progressive experience achieved in the course of the years. Failures mainly occur through insufficient application of physical, chemical or ecological principles. Spontaneous colonization by plants and animals, following habitat reconstruction, is preferred. However, sometimes the re-introduction of keystone species (e.g. eelgrass, salmon, beaver) is necessary in case the potential habitats are isolated or fragmented, or if a seed bank is lacking, thus not allowing viable populations to develop. Re-introducing traditional management techniques (e.g. mowing without fertilization, low intensity grazing) is important to rehabilitate the semi-natural and cultural landscapes that are so characteristic for The Netherlands.
Download or read book Restoration of Aquatic Ecosystems written by National Research Council and published by National Academies Press. This book was released on 1992-01-01 with total page 580 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
