Book excerpt: The states of Delaware and Maryland are cooperating to investigate and evaluate wetlands of the Nanticoke River watershed. They are collecting data on reference wetlands to gain information on wetland functions and levels of performance for evaluating impacts to presentday wetlands and to develop a watershed-based strategy for wetland conservation and restoration. The U.S. Fish and Wildlife Service is assisting the states in several ways. Roughly two years ago, the states provided funds to the U.S. Fish and Wildlife Service to expand the current National Wetlands Inventory (NWI) digital data to include hydrogeomorphic-type descriptors (i.e., landscape position, landform, and water flow path) to all mapped wetlands and to use these data to produce a preliminary assessment of wetland functions for the watershed. The results of this analysis were published in two watershed-based reports on the Nanticoke wetlands, one for Maryland and the other for Delaware (Tiner et al. 2000, 2001).

This book was released on 2015-02-14 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: Today there is great interest in managing wetland resources from a watershed standpoint or landscape perspective. Wetland managers need information on a variety of topics including the location and type of existing wetlands, wetland functions, potential wetland restoration sites, and the overall condition of natural habitat in the watershed. The U.S. Fish and Wildlife Service's National Wetlands Inventory Program has developed products that expand the use of its conventional maps and digital products to aid in resource management. The Delaware Department of Natural Resources and Environmental Control (DNREC) is attempting to reduce nonpoint source pollution impacts in the Nanticoke watershed and wanted the above information for the Delaware portion of the Nanticoke River watershed. This information would be used to help improve water quality and management and conservation of fish and wildlife habitat in wetlands, streams, riparian areas, and uplands in Delaware. Similar work has recently been completed for the Maryland portion of the watershed (Tiner et al. 2000). In the future, both efforts may be combined into a single report.
Download or read book Wetland and Stream Rapid Assessments written by John Dorney and published by Academic Press. This book was released on 2018-08-07 with total page 582 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wetland and Stream Rapid Assessments: Development, Validation, and Application describes the scientific and environmental policy background for rapid wetland and stream assessments, how such assessment methods are developed and statistically verified, and how they can be used in environmental decision-making—including wetland and stream permitting. In addition, it provides several case studies of method development and use in various parts of the world. Readers will find guidance on developing and testing such methods, along with examples of how these methods have been used in various programs across North America. Rapid wetland and stream functional assessments are becoming frequently used methods in federal, state and local environmental permitting programs in North America. Many governments are interested in developing new methods or improving existing methods for their own jurisdictions. This book provides an ideal guide to these initiatives. Offers guidance for the use and evaluation of rapid assessments to developers and users of these methods, as well as students of wetland and stream quality Contains contributions from sources who are successful in academia, industry and government, bringing credibility and relevance to the content Includes a statistically-based approach to testing the validity of the rapid method, which is very important to the usefulness and defensibility of assessment methods
Download or read book Correlating Enhanced National Wetlands Inventory Data with Wetland Functions for Watershed Assessments written by U. S. Fish and Wildlife Service and published by CreateSpace. This book was released on 2013-04-19 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the mid-1990s, a set of hgm-type descriptors were developed to describe a wetland's landscape position, landform, and water flow path (Tiner 1995, 1996a, b). Use of the initial set of keys for pilot watershed projects lead to a refinement and expansion of the keys in subsequent years (Tiner 1997a, 2000, 2002, 2003). These projects were watershed characterizations that included a preliminary assessment of wetland functions as a main component or the prime component of the study. The reports addressed the following watersheds: Casco Bay (Maine; Tiner et al. 1999), Nanticoke River (Maryland and Delaware; Tiner et al. 2000, 2001), Coastal Bays (Maryland; Tiner et al. 2000), and Cannonsville and Neversink Reservoirs (New York; Tiner et al. 2002), as well as the Pennsylvania Coastal Zone (Tiner and DeAlessio 2002)

Available in PDF, EPUB and Kindle. Book excerpt: “Wetland Habitats of North America is essential reading for everyone who studies, manages, or visits North American wetlands. It fills an important void in the wetland literature, providing accessible and succinct descriptions of all of the continent’s major wetland types.” Arnold van der Valk, Iowa State University “Batzer and Baldwin have compiled the most comprehensive compendium of North American wetland habitats and their ecology that is presently available—a must for wetland scientists and managers.” Irving A. Mendelssohn, Louisiana State University "If you want to gain a broad understanding of the ecology of North America’s diverse wetlands, Wetland Habitats of North America is the book for you. Darold Batzer and Andrew Baldwin have assembled an impressive group of regional wetland scientists who have produced a virtual encyclopedia to the continent’s wetlands. Reading the book is like a road trip across the Americas with guided tours of major wetland types by local experts. Your first stop will be to coastal wetlands with eight chapters covering tidal wetlands along the Atlantic, Gulf, and Pacific coasts. Then you’ll travel inland where you can visit any or all of 18 types ranging from bottomland swamps of the Southeast to pothole marshes of the Northern Prairies to montane wetlands of the Rockies to tropical swamps of Central America and desert springs wetlands. All in one book—I’m impressed! Every wetlander should add this book to her or his swampland library. Ralph Tiner, University of Massachusetts–Amherst
Download or read book Compensating for Wetland Losses Under the Clean Water Act written by National Research Council and published by National Academies Press. This book was released on 2001-11-06 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recognizing the importance of wetland protection, the Bush administration in 1988 endorsed the goal of "no net loss" of wetlands. Specifically, it directed that filling of wetlands should be avoided, and minimized when it cannot be avoided. When filling is permitted, compensatory mitigation must be undertaken; that is, wetlands must be restored, created, enhanced, and, in exceptional cases, preserved, to replace the permitted loss of wetland area and function, such as water quality improvement within the watershed. After more than a dozen years, the national commitment to "no net loss" of wetlands has been evaluated. This new book explores the adequacy of science and technology for replacing wetland function and the effectiveness of the federal program of compensatory mitigation in accomplishing the nation's goal of clean water. It examines the regulatory framework for permitting wetland filling and requiring mitigation, compares the mitigation institutions that are in use, and addresses the problems that agencies face in ensuring sustainability of mitigated wetlands over the long term. Gleaning lessons from the mixed results of mitigation efforts to date, the book offers 10 practical guidelines for establishing and monitoring mitigated wetlands. It also recommends that federal, state, and local agencies undertake specific institutional reforms. This book will be important to anyone seeking a comprehensive understanding of the "no net loss" issue: policy makers, regulators, environmental scientists, educators, and wetland advocates.

Download or read book The World s Largest Wetlands written by Lauchlan H. Fraser and published by Cambridge University Press. This book was released on 2009-08-10 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the past century approximately fifty percent of the world's wetlands have been destroyed, largely due to human activities. Increased human population has lead to shrinkage of wetland areas, and data show that as they shrink, their important functions decline. Reduced wetland area causes more flooding in Spring, less available water during drought, greater risk of water pollution, and less food production and reduced carbon storage. Much of the remaining pristine wetland systems are found in the world's largest wetlands, and yet these areas have received surprisingly little scientific research or attention. This volume presents the views of leading experts on each of the world's largest wetland systems. Here, this international team of authors share their understanding of the ecological dynamics of large wetlands and their significance, and emphasise their need of conservation.

Download or read book Wetlands written by Committee on Characterization of Wetlands and published by National Academies Press. This book was released on 1995-09-20 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: "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.
