Book Description
Minnesota's 3.6 million ha of wetlands have been impacted by a variety of human activities, including agricultural drainage, urbanization, water control, and no-point source pollution. More than half of Minnesota's wetlands have been destroyed since the first European settlers arrived, an average loss of about 35,600 ha/yr. Drainage for agriculture is the major cause of wetland loss in Minnesota, particularly in southern Minnesota and the Red River Valley. In addition to impacting wetlands directly, wetland drainage affects downstream areas by increasing flood flows, and releasing sediment and nutrients. Urban development and highway construction affect a smaller proportion of Minnesota's wetlands, but substantially alter their physical, chemical, and biological properties. Hydrology has a major influence on the structure and function of wetlands, so changes in the frequency, duration, depth, and timing of wetland flooding can severely impact wetlands. While wetlands can assimilate low levels of sediment and nutrients enrichment, excessive inputs can be detrimental. Peat harvesting is not currently extensive in Minnesota, but could cause substantial impacts. Cumulative impact, the incremental impact of an action when added to other past, present, and reasonably foreseeable future actions, is becoming an area of increasing concern.

Book Description
The wetlands of Minnesota and Wisconsin are categorized into fifteen plant communities. Each community is described and illustrated by color photographs, along with descriptions and color photographs of a total of 115 representative plant species. The descriptions include taxonomic characteristics, habitat, and notes on wildlife use and economic values.

Book Description
The Wetland Book is a comprehensive resource aimed at supporting the trans- and multidisciplinary research and practice which is inherent to this field. Aware both that wetlands research is on the rise and that researchers and students are often working or learning across several disciplines, The Wetland Book is a readily accessible online and print reference which will be the first port of call on key concepts in wetlands science and management. This easy-to-follow reference will allow multidisciplinary teams and transdisciplinary individuals to look up terms, access further details, read overviews on key issues and navigate to key articles selected by experts.

Book Description
Wetlands are, by their very nature, ephemeral and transitional, which makes them challenging to characterize. Yet the need for characterizing wetlands continues to grow, particularly as we develop a better understanding of the wealth of ecosystem services that they provide. Wetland Landscape Characterization: Practical Tools, Methods, and Approaches for Landscape Ecology, Second Edition shows how wetland characterization tools, methods, and approaches can be integrated to more effectively address twenty-first-century wetland issues. A Practical Toolbox for Integrated Wetland Landscape Characterization The book explains how to locate, identify, and map the extent of wetlands to learn more about their importance to society and the larger landscape. It examines jurisdictional, regulatory, and practical applications from the scientific, engineering, and lay perspectives. Fully updated, the second edition reflects an emerging infrastructural, ecosystem goods-and-services perspective to better assist readers who may encounter these concepts and challenges as they assess and characterize wetlands. Examples and case studies illustrate a variety of situations and solutions, highlighting the use of current techniques to assess, inventory, and monitor natural resources under changing conditions. These examples offer lessons and ideas for the issues encountered every day by wetland landscape ecology practitioners. The book also refers readers to additional resources to help them solve specific challenges. New in This Edition Updates of practical geospatial methods More project-driven examples A description of the pitfalls of using ecological data at landscape scales, along with solutions Alternative techniques for a variety of practitioners Linkages between field and landscape ecological practices Online resources for practitioners New illustrations This book helps readers develop the concepts, skills, and understanding of how to best achieve project goals in the rapidly changing disciplines of landscape science and wetland ecology and management. A valuable resource, it provides practical tools, methods, and approaches for conceptualizing, designing, and implementing broad-scale wetland projects that take into account critical societal linkages.
