Wetlands are a vital part of the landscape and ecology of the United States, providing food and shelter for species ranging from the beautiful wood duck to the tiny fairy shrimp. These areas provide critical habitat for fish and wildlife, protect communities from flooding, and recharge groundwater supplies—yet they continue to be destroyed at an alarming rate. A detailed analysis of wetlands management, Wetland Drainage, Restoration, and Repair is a comprehensive guide to the past, present, and future of wetland recovery in the United States. The book includes a historical overview of wetland destruction and repair over the past two hundred years and also serves as a unique resource for anyone, from novice to engineer, interested in the process of wetland restoration. Author Thomas R. Biebighauser draws from his own vast experience in building and repairing more than 950 wetlands across North America. Included are numerous photographs and case studies that highlight successes of past projects. Detailed, step-by-step instructions guide the reader through the planning and implementation of each restoration action. Biebighauser also provides a number of effective strategies for initiating and improving funding for wetlands programs. Wetland Drainage, Restoration, and Repair is essential reading for all who care about and for these important ecosystems.
Underdraining has been recognized as one of the major capital-intensive agricultural improvements of the nineteenth century. Over half the agricultural area of England is subject to waterlogging and is in need of some form of underdraining, rendering the improvement both technically and economically basic to much of English agriculture. By removing excess soil water, the object of underdraining was to reproduce as far as possible the conditions of free-draining land, which was workable all year round, and to create an optimum soil-moisture content for both plant growth and cultivation. Despite the necessity for the improvement, a wide-ranging debate exists in the literature on the extent, effectiveness and agricultural importance of underdraining in the nineteenth century. The present study attempts to resolve this debate. By examining the evidence of draining loans under the Public Money Draining Acts and of the various land improvement companies and the accounts of estates in Devon, Northamptonshire and Northumberland, a precise record has been provided for the, first of the spread of underdraining in England in the nineteenth century, of the factors involved in its adoption and of its impact on agricultural practice in that period.
