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.

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.

While it is generally accepted that flood pulsing and disturbance dynamics are critical to wetland viability, there is as yet no consensus among those responsible for wetland restoration about how best to plan for those phenomena or even whether it is really necessary to do so at all. In this groundbreaking book, Dr. Beth Middleton draws upon the latest research from around the world to build a strong case for making flood pulsing and disturbance dynamics integral to the wetland restoration planning process. While the initial chapters of the book are devoted to laying the conceptual foundations, most of the coverage is concerned with demonstrating the practical implications for wetland restoration and management of the latest ecological theory and research. It includes a fascinating case history section in which Dr. Middleton explores the restoration models used in five major North American, European, Australian, African, and Asian wetland projects, and analyzes their relative success from the perspective of flood pulsing and disturbance dynamics planning. Wetland Restoration also features a wealth of practical information useful to all those involved in wetland restoration and management, including: A compendium of water level tolerances, seed germination, seedling recruitment, adult survival rates, and other key traits of wetland plant species A bibliography of 1,200 articles and monographs covering all aspects of wetland restoration A comprehensive directory of wetland restoration ftp sites worldwide An extensive glossary of essential terms Wetland Restoration, Flood Pulsing, and Disturbance Dynamics is a valuable working resource for wetland restoration consultants, employees of government agencies, and professional land managers, as well as ecologists, foresters, and geologists involved with wetland restoration and management. It is also an excellent text for advanced courses in wetland restoration.

This thesis aims to develop a conceptual understanding of the flooding patterns and vegetation response of large floodplain wetlands, and to apply this knowledge to develop an innundation and vegetation response model for water management. Applicable to a range of floodplain wetland systems, the conceptual node-network approach was developed in relation to the Gwydir wetlands, NSW, Australia. The Gwydir floodplains and wetlands occur in a dryland setting and are reliant on flows from the upstream catchment that has substantial water resource development. The Gwydir wetlands include a range of ecological values and are listed under international agreements for the protection of wetlands and migratory waterbirds.

Floodplains provides an overview of floodplains and their management in temperate regions. It synthesizes decades of research on floodplain ecosystems, explaining hydrologic, geomorphic, and ecological processes and how under appropriate management these processes can provide benefits to society ranging from healthy fish populations to flood-risk reduction. Drawing on the framework of reconciliation ecology, the authors explore how new concepts for floodplain ecosystem restoration and management can increase these benefits. Additionally, they use case studies from California’s Central Valley and other temperate regions to show how innovative management approaches are reshaping rivers and floodplains around the world.

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).
