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.

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.

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.

Most aquatic ecosystems have variable water levels. These water-level fluctuations (WLF) have multiple effects on the organisms above and below the waterline. Natural WLF patterns in lakes guarantee both productivity and biodiversity, while untimely floods and droughts may have negative effects. Human impacts on WLF have led to a stabilization of the water levels of many lakes by hydraulic regulation, untimely drawdown due to water use, or floods due to water release from hydropower plants in the catchments. This book provides a first review in this field. It presents selected papers on the ecological effects of WLF in lakes, resulting from a workshop at the University of Konstanz in winter 2005. Issues addressed here include the extent of WLF, and analyses of their effects on different groups of biota from microorganisms to vertebrates. Applied issues include recommendations for the hydrological management of regulated lakes to reduce negative impacts, and a conceptual framework is delivered by an extension of the floodpulse concept for lakes. Current impacts on water use, including increasing demands on drinking and irrigation water, hydropower etc., and climate change effects on WLF make this book an essential resource for aquatic ecologists, engineers, and decision-makers dealing with the management of lake ecosystems and their catchments.

Understand the current concept of wetland and methods for identifying, describing, classifying, and delineating wetlands in the United States with Wetland Indicators - capturing the current state of science's role in wetland recognition and mapping. Environmental scientists and others involved with wetland regulations can strengthen their knowledge about wetlands, and the use of various indicators, to support their decisions on difficult wetland determinations. Professor Tiner primarily focuses on plants, soils, and other signs of wetland hydrology in the soil, or on the surface of wetlands in his discussion of Wetland Indicators. Practicing - and aspiring - wetland delineators alike will appreciate Wetland Indicators' critical insight into the development and significance of hydrophytic vegetation, hydric soils, and other factors. Features Color images throughout illustrate wetland indicators. Incorporates analysis and coverage of the latest Army Corps of Engineers delineation manual. Provides over 60 tables, including extensive tables of U.S. wetland plant communities and examples for determining hydrophytic vegetation.
