"This manual is based on the authors' experience teaching the Wetland Assessment Training Course to employees of the Chinese National Environmental Protection Agency (CNEPA) at Nanchang, Jiangxi Province, October 1986 and at Tongliao, Inner Mongolian Autonomous Region, august 1987, Peoples Republic of China. the object of the course was to provide a basic introduction to freshwater wetlands, their functions and preliminary techniques by which to screen wetlands for potential functions. Minimal acquaintance with wetlands, as systems, was assumed and emphasis was put on functions important to subsistence economies and sustainable utilization. The manual is designed to be used by an instructor who has taken the course or who has had training in wetland functions and assessment. It is an outline on which not all of the concepts and procedures are fully developed. It is intended to serve as an instructional guide to course topics and organization, and a framework for student note taking, discussion, and as an aide to bridging a language barrier. We recommend that instructors use the books listed in section 11.0 as prime sources while instructing the course. We have drawn from them extensively."--Page ii

Wetlands perform functions that deliver benefits to society, often referred to as ecosystem services. These ecosystem services include water supply, flood regulation, water purification, climate regulation, biodiversity, agriculture (e.g. grazing land), and amenity. A functional approach to wetland assessment enables a holistic view to be taken of the wide range of services wetlands can provide. The functional assessment procedures (FAPs) in this volume translate best available scientific knowledge into reasonable predictions of how component parts of wetlands function in different landscape contexts. They can be used to indicate the potential and priorities for management options in such areas as flood control, pollution reduction and biodiversity conservation.Functional assessment enables the user to predict the functioning of a wetland area without the need for comprehensive and expensive empirical research The FAPs therefore provide a methodology that can be used by both experts and non-experts to assess wetland functioning relatively rapidly. The volume includes an electronic version of the FAPs on CD which automates aspects of the assessment once the initial recording stage is completed. It is anticipated that the FAPs will be used by a range of individuals or organisations concerned with wetland management who wish to gain a better understanding of the processes, functions, services or benefits and potential of the wetlands for which they have responsibility. - Provides a systematic methodology to evaluate how wetlands function - Allows non-experts to assess wetland functioning rapidly and cost-effectively - Automates aspects of the functional assessment through the accompanying CD-ROM

New focused text introduces readers to wetland ecosystems and systems approaches to studying wetlands With its comprehensive coverage of wetland science, management, and restoration, Mitsch and Gosselink's Wetlands has been the premier reference on wetlands for more than two decades. Now, the coverage of specific wetland ecosystem types from earlier editions of this acclaimed work has been updated, revised, and supplemented with additional content in order to create this new text focusing exclusively on wetland ecosystems. This book now complements Wetlands, Fourth Edition. Following an introduction to ecosystems in general and wetland ecosystems in particular, Wetland Ecosystems examines the major types of wetlands found throughout the world: coastal wetlands, freshwater marshes and forested swamps, and peatlands. The final chapter reviews three fundamental systems approaches to studying wetlands: mesocosms, full-scale experimental ecosystems, and mathematical modeling. This new text features: Updated descriptions of the hydrology, biogeochemistry, and biology of the main types of wetlands found in the world New content introducing general ecosystems, wetland ecosystems, whole ecosystem and mesocosm experiments with wetlands, and systems ecology and modeling A detailed description of the ecosystem services provided by wetlands A broad international scope, including many examples of wetlands located outside North America Two new coauthors offering new perspectives and additional insights into the latest ecosystem and modeling techniques An abundance of illustrations helps readers understand how different biological communities and the abiotic environment in wetland ecosystems interact and function. Tables and text boxes provide at-a-glance summaries of key information. Lastly, each chapter concludes with a list of recommended readings. This text has been designed as an introduction for students and professionals in wetland ecology and management, general ecology, environmental science, and natural resource management.

"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.

Global wetlands exhibit significant differences in both hydrology and species composition and range from moss-dominated arctic peatlands to seasonally-flooded tropical floodplains. They are increasingly recognized for the important services that they provide to both the environment and human society such as wildlife and fish production, nutrient filtering, and carbon sequestration. A combination of low oxygen levels and dense plant canopies present particular challenges for organisms living in this aquatic habitat. This concise textbook discusses the universal environmental and biological features of wetland habitats, with an emphasis on wetland plants and animals and their adaptations. It also describes the functional features of wetlands - primary production, litter decomposition, food webs, and nutrient cycling - and their significance locally and globally. The future of wetlands is examined, including the potential threats of global climate change and invasive species, as well as their restoration and creation. This new edition maintains the structure and style of the first, but is fully updated throughout with new chapters on invasive species, restoration/creation, global climate change, and the value of wetlands.

The first resource of its kind-essential practical guidance on wetlands bioassessment and management Although bioassessment has become a vital tool in the successful management of many aquatic ecosystems, to date there has been no single book that covers the application of bioassessment principles to wetland ecosystems. This contributed volume fills this important gap in the literature, with a multifaceted look at the issues and techniques involved in the successful bioassessment and management of freshwater wetlands. The book is divided into two parts-bioassessment and wildlife management. After a review of general bioassessment principles, Part I discusses the statistical issues related to sampling numerous sites, as well as the application of multivariate procedures and invertebrate functional groups to wetland bioassessment. A series of case studies examines bioassessment results using various organismal groups, followed by several chapters that trace the relationship between bioassessment and wetland restoration. Coverage also explores how to use and sample bacteria, algae, macrophytes, and invertebrates. Part II covers key management topics, including many that are frequently overlooked in other treatments of the subject. Separate chapters discuss how to manage fish, waterbirds, and mosquitoes in wetlands. Other chapters address timber harvest strategies and impact assessment, as well as the biological control of an invasive wetland plant. As wetland managers work to strike a vital balance between resource exploitation and resource protection, this book offers an important repository of practical information to use in meeting this formidable challenge. It will be welcomed by wetland managers and scientists, environmental engineers, ecologists, civil engineers, and others whose work involves wetlands study and management.
