Fish U.S. Fish and Wildlife Service and published by CreateSpace. This book was released on 2015-02-14 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: The U.S. Fish and Wildlife Service has been conducting the National Wetlands Inventory for over 25 years. The NWI Program has produced wetland maps for 91% (78% final) of the lower 48 states, all of Hawaii, and 35% of Alaska. Wetlands are classified according to the Service's official wetland classification system (Cowardin et al. 1979). This classification describes wetlands by ecological system (Marine, Estuarine, Lacustrine, Riverine, and Palustrine), by subsystem (e.g., water depth, exposure to tides), class (vegetative life form or substrate type), subclass, water regimes (hydrology), water chemistry (pH and salinity), and special modifiers (e.g., alterations by humans). The maps have been converted to digital data for 47% of the lower 48 states and 18% of Alaska. The availability of digital data and geographic information system (GIS) technology make it possible to use NWI data for various geospatial analyses.

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)
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 Wetland Techniques written by James T. Anderson and published by Springer Science & Business Media. This book was released on 2013-10-10 with total page 281 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wetlands serve many important functions and provide numerous ecological services such as clean water, wildlife habitat, nutrient reduction, and flood control. Wetland science is a relatively young discipline but is a rapidly growing field due to an enhanced understanding of the importance of wetlands and the numerous laws and policies that have been developed to protect these areas. This growth is demonstrated by the creation and growth of the Society of Wetland Scientists which was formed in 1980 and now has a membership of 3,500 people. It is also illustrated by the existence of 2 journals (Wetlands and Wetlands Ecology and Management) devoted entirely to wetlands. To date there has been no practical, comprehensive techniques book centered on wetlands, and written for wetland researchers, students, and managers. This techniques book aims to fill that gap. It is designed to provide an overview of the various methods that have been used or developed by researchers and practitioners to study, monitor, manage, or create wetlands. Including many methods usually found only in the peer-reviewed or gray literature, this 3-volume set fills a major niche for all professionals dealing with wetlands.

This book was released on 2015-02-14 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Georgia Department of Natural Resources (GA DNR) has recently updated National Wetlands Inventory (NWI) data for the state's six coastal counties. The U.S. Fish and Wildlife Service (Service) has recognized the potential application of NWI data for watershed assessments, but realized that other attributes would have to be added to the data to facilitate functional analysis. In the early 1990s, Dr. Mark Brinson conceived a hydrogeomorphic approach to wetland functional assessment that uses comparison of field-verified properties of existing wetlands to those from a set of reference wetlands as a means of assessing a wetland's proximity to or departure from reference condition (Brinson 1993a). This approach provided the impetus for the Service to develop other attributes to expand the NWI database and make it more useful as a tool for landscape-level functional assessment of wetlands.

Download or read book Wading Right In written by Catherine Owen Koning and published by University of Chicago Press. This book was released on 2019-08-09 with total page 277 pages. Available in PDF, EPUB and Kindle. Book excerpt: Where can you find mosses that change landscapes, salamanders with algae in their skin, and carnivorous plants containing whole ecosystems in their furled leaves? Where can you find swamp-trompers, wildlife watchers, marsh managers, and mud-mad scientists? In wetlands, those complex habitats that play such vital ecological roles. In Wading Right In, Catherine Owen Koning and Sharon M. Ashworth take us on a journey into wetlands through stories from the people who wade in the muck. Traveling alongside scientists, explorers, and kids with waders and nets, the authors uncover the inextricably entwined relationships between the water flows, natural chemistry, soils, flora, and fauna of our floodplain forests, fens, bogs, marshes, and mires. Tales of mighty efforts to protect rare orchids, restore salt marshes, and preserve sedge meadows become portals through which we visit major wetland types and discover their secrets, while also learning critical ecological lessons. The United States still loses wetlands at a rate of 13,800 acres per year. Such loss diminishes the water quality of our rivers and lakes, depletes our capacity for flood control, reduces our ability to mitigate climate change, and further impoverishes our biodiversity. Koning and Ashworth’s stories captivate the imagination and inspire the emotional and intellectual connections we need to commit to protecting these magical and mysterious places.

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.

Available in PDF, EPUB and Kindle. Book excerpt: "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
