Book excerpt: I tested the impacts of flood-pulsing on wetland invertebrates and plants along small streams in northeast Ohio. The Flood Pulse Concept (FPC) was developed in large rivers (e.g. Amazon, Danube, and Mississippi rivers). It describes the ecological impacts when rivers flood adjacent riparian habitats, which are a mosaic of permanent flooded wetlands, intermittently flooded wetlands, and terrestrial habitats. Flood-pulsing produces resource subsidies (e.g., water, nutrients, organic matter). Flooding also creates stresses (anoxia, desiccation, high levels of toxins, sediment erosion and deposition) in the wetlands. Floodplain biota are adapted to the predictable flood regime in large rivers. Furthermore, coarse woody debris (CWD) from fallen trees provides a microclimatic refugia for soil organisms in floodplains. As a result, biodiversity and production are usually higher in flood-pulsing wetlands than other wetland habitats. In my dissertation, I used wetland mesocosms at the on-campus Herrick Aquatic Ecology Research Facility (HAERF) to test how the short unpredictable floods in small streams affect wetland plants and invertebrates. I found that flood pulsing creates stresses that control plant community structure in the intermittently flooded zone. There was lower emergent plant diversity and plant cover in the flood-pulse treatment. However, aquatic invertebrates and plants in permanently flooded pools were not affected. I also sampled emerging insects in flood-plain wetlands at Mud Brook Preserve (MBP) and at HAERF. Insect communities were different in permanent pools and intermittently flooded zone at MBP showing that drawdowns are an important environmental factor. The permanent pools at HAERF and MBP were also different, suggesting that mesocosms did not simulate all natural environmental conditions. I tested the impact of CWD by testing naturally and artificially felled trees. Invertebrate communities were varied by region of the floodplain. However, there were few differences in sites with and without CWD suggesting that habitat conditions (soil moisture, temperature) structure soil invertebrate communities. While CWD had few short-term impacts it may be significant at a landscape scale. Overall, the unpredictable short floods in headwater wetlands create both benefits and stressors, but the net impact was negative. Therefore, some aspects of the Flood pulse concept are not applicable to headwater systems.

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.

Book Synopsis Flood Pulsing in Wetlands by : Beth A. Middleton
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.

Book Synopsis Wetlands by : Committee on Characterization of Wetlands
Download or read book Wetlands written by Committee on Characterization of Wetlands and published by National Academies Press. This book was released on 1995-09-20 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Wetlands" has become a hot word in the current environmental debate. But what does it signify? In 1991, proposed changes in the legal definities of wetlands stirred controversy and focused attention on the scientific and economic aspects of their management. This volume explores how to define wetlands. The committee--whose members were drawn from academia, government, business, and the environmental community--builds a rational, scientific basis for delineating wetlands in the landscape and offers recommendations for further action. Wetlands also discusses the diverse hydrological and ecological functions of wetlands, and makes recommendations concerning so-called controversial areas such as permafrost wetlands, riparian ecosystems, irregularly flooded sites, and agricultural wetlands. It presents criteria for identifying wetlands and explores the problems of applying those criteria when there are seasonal changes in water levels. This comprehensive and practical volume will be of interest to environmental scientists and advocates, hydrologists, policymakers, regulators, faculty, researchers, and students of environmental studies.

For the first time, Tropical Stream Ecology places an important emphasis on viewing research carried out in contributions from international literature. First synthetic account of the ecology of all types of tropical streams Covers all of the major tropical regions Detailed consideration of possible fundamental differences between tropical and temperate stream ecosystems Threats faced by tropical stream ecosystems and possible conservation actions Descriptions and synstheses life-histories and breeding patterns of major aquatic consumers (fishes, invertebrates)
Book Synopsis Compensating for Wetland Losses Under the Clean Water Act by : National Research Council
Download or read book Compensating for Wetland Losses Under the Clean Water Act written by National Research Council and published by National Academies Press. This book was released on 2001-11-06 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recognizing the importance of wetland protection, the Bush administration in 1988 endorsed the goal of "no net loss" of wetlands. Specifically, it directed that filling of wetlands should be avoided, and minimized when it cannot be avoided. When filling is permitted, compensatory mitigation must be undertaken; that is, wetlands must be restored, created, enhanced, and, in exceptional cases, preserved, to replace the permitted loss of wetland area and function, such as water quality improvement within the watershed. After more than a dozen years, the national commitment to "no net loss" of wetlands has been evaluated. This new book explores the adequacy of science and technology for replacing wetland function and the effectiveness of the federal program of compensatory mitigation in accomplishing the nation's goal of clean water. It examines the regulatory framework for permitting wetland filling and requiring mitigation, compares the mitigation institutions that are in use, and addresses the problems that agencies face in ensuring sustainability of mitigated wetlands over the long term. Gleaning lessons from the mixed results of mitigation efforts to date, the book offers 10 practical guidelines for establishing and monitoring mitigated wetlands. It also recommends that federal, state, and local agencies undertake specific institutional reforms. This book will be important to anyone seeking a comprehensive understanding of the "no net loss" issue: policy makers, regulators, environmental scientists, educators, and wetland advocates.
