This book was released on 2012 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: Accurate estimates of wetlands and stream extent provide context for scientific investigations, enable informed management, and measure progress towards no-net-loss policy goals. However, the default approach for monitoring extent, comprehensive mapping, is prohibitively resource intensive over large areas, making it both impractical and statistically unreliable. Therefore, a number of national and state-level programs have begun to employ probabilistic approaches to monitor wetland and stream extent. These programs have proven practical for their intended applications but little information exists about the ability of the designs to meet diverse, state-level information needs such as accurately capturing rare wetland types or detecting small-scale changes in extent or spatial distribution. Here, I utilized a simulated sampling approach to empirically model and evaluate probabilistic methods for monitoring wetland and stream extent in California. The optimized design was then directly validated against comprehensive mapping through a pilot-scale implementation. The flexibility of the simulated sampling method enabled assessment of performance for a variety of objectives, beyond statistical precision. By employing this unique approach to sampling design, the results could be customized for the specific information needs of California. Results indicate that generalized random tessellation stratified (GRTS) sampling, a spatially balanced selection methodology, provides significant advantages over simple random sampling or stratification. In addition, fixed sampling locations over time provide the best power for both estimating the current extent and detecting changes in extent over time. The pilot-scale implementation was conducted in two separate regions of California. By using regions with existing, comprehensive aquatic resource maps, a direct comparison was made between the probabilistic and comprehensive mapping efforts. The pilot produced precise estimates of aquatic resource extent but suggested that mapping and classification methodologies may require more standardization in order to compare estimates between probabilistic approaches and comprehensive maps. In addition to systematic methodological differences, additional simulated sampling suggests that the expected accuracy of the 95% confidence interval is, in fact, dependent on the sample size. Final design conclusions from this dissertation will be recommended to the State of California for implementation in a California S & T program for aquatic resource extent.

This book was released on 2020-03-03 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first comprehensive environmental history of California’s Great Central Valley, where extensive freshwater and tidal wetlands once provided critical habitat for tens of millions of migratory waterfowl. Weaving together ecology, grassroots politics, and public policy, Philip Garone tells how California’s wetlands were nearly obliterated by vast irrigation and reclamation projects, but have been brought back from the brink of total destruction by the organized efforts of duck hunters, whistle-blowing scientists, and a broad coalition of conservationists. Garone examines the many demands that have been made on the Valley’s natural resources, especially by large-scale agriculture, and traces the unforeseen ecological consequences of our unrestrained manipulation of nature. He also investigates changing public and scientific attitudes that are now ushering in an era of unprecedented protection for wildlife and wetlands in California and the nation.

Download or read book Wetland Carbon and Environmental Management written by Ken W. Krauss and published by John Wiley & Sons. This book was released on 2021-11-23 with total page 484 pages. Available in PDF, EPUB and Kindle. Book excerpt: Explores how the management of wetlands can influence carbon storage and fluxes. Wetlands are vital natural assets, including their ability to take-up atmospheric carbon and restrict subsequent carbon loss to facilitate long-term storage. They can be deliberately managed to provide a natural solution to mitigate climate change, as well as to help offset direct losses of wetlands from various land-use changes and natural drivers. Wetland Carbon and Environmental Management presents a collection of wetland research studies from around the world to demonstrate how environmental management can improve carbon sequestration while enhancing wetland health and function. Volume highlights include: Overview of carbon storage in the landscape Introduction to wetland management practices Comparisons of natural, managed, and converted wetlands Impact of wetland management on carbon storage or loss Techniques for scientific assessment of wetland carbon processes Case studies covering tropical, coastal, inland, and northern wetlands Primer for carbon offset trading programs and how wetlands might contribute The American Geophysical Union promotes discovery in Earth and space science for the benefit of humanity.Its publications disseminate scientific knowledge and provide resources for researchers, students, and professionals.

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.
