Available in PDF, EPUB and Kindle. Book excerpt: Analyses of relationships between hydric soils and wetland plant species were made at a site in the northern foothills of the Brooks Range, Alaska, as part of a cooperative effort between the U.S. Fish and Wildlife Service and Soil Conservation Service to develop methods for field identification of wetlands and hydric soils. The site is considered to be representative of broad regions of acidic tussock tundra in the foothills. Seven soil types (subgroups) were identified at the site. All except two are considered hydric.

Download or read book Arctic Climate Impact Assessment Scientific Report written by Arctic Climate Impact Assessment and published by Cambridge University Press. This book was released on 2005-11-07 with total page 1053 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Arctic is now experiencing some of the most rapid and severe climate change on earth. Over the next 100 years, climate change is expected to accelerate, contributing to major physical, ecological, social, and economic changes, many of which have already begun. Changes in arctic climate will also affect the rest of the world through increased global warming and rising sea levels. Arctic Climate Impact Assessment was prepared by an international team of over 300 scientists, experts, and knowledgeable members of indigenous communities. The report has been thoroughly researched, is fully referenced, and provides the first comprehensive evaluation of arctic climate change, changes in ultraviolet radiation and their impacts for the region and for the world. It is illustrated in full color throughout. The results provided the scientific foundations for the ACIA synthesis report - Impacts of a Warming Arctic - published by Cambridge University Press in 2004.

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.

Download or read book Current Issues in Alaska Wetland Management written by Charles H. Racine and published by . This book was released on 1994 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although wetlands cover over half of Alaska, the status, management and regulation of these areas is problematic. The technical literature on Alaskan wetland vegetation, soils and hydrology is abundant, but the application of the literature to wetland management is poorly developed. This report identifies problems, issues and information gaps in the management of Alaskan wetlands. There are numerous arguments and debates on the designation, function and values, and disturbance of certain wetlands in Alaska. Permafrost, fire cycles and unique hydrologic regimes complicate the designation and delineation of Alaskan wetlands. The functions and values of most Alaskan wetlands clearly lie in their importance as habitat, particularly for migrating waterbirds, but an understanding of their role in flood water storage, water quality improvement, subsistence and other functions remains controversial and in need of study. Disturbance and other impacts on Alaskan wetlands is small relative to the large area that wetlands cover and in comparison with the loss of wetlands in the lower 48 states. However, several development projects in Alaska have affected large wetland areas and methods to restore these wetlands are being developed. Cumulative impacts are unknown, as are techniques for restoring permafrost wetlands containing gravel fill.

Download or read book Wetland Indicators written by Ralph W. Tiner and published by CRC Press. This book was released on 2016-12-19 with total page 588 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understand the current concept of wetland and methods for identifying, describing, classifying, and delineating wetlands in the United States with Wetland Indicators - capturing the current state of science's role in wetland recognition and mapping. Environmental scientists and others involved with wetland regulations can strengthen their knowledge about wetlands, and the use of various indicators, to support their decisions on difficult wetland determinations. Professor Tiner primarily focuses on plants, soils, and other signs of wetland hydrology in the soil, or on the surface of wetlands in his discussion of Wetland Indicators. Practicing - and aspiring - wetland delineators alike will appreciate Wetland Indicators' critical insight into the development and significance of hydrophytic vegetation, hydric soils, and other factors. Features Color images throughout illustrate wetland indicators. Incorporates analysis and coverage of the latest Army Corps of Engineers delineation manual. Provides over 60 tables, including extensive tables of U.S. wetland plant communities and examples for determining hydrophytic vegetation.

Download or read book Managing for Enhancement of Riparian and Wetland Areas of the Western United States written by David A. Koehler and published by . This book was released on 2000 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: This annotated bibliography contains 1,905 citations from professional journals, symposia, workshops, proceedings, technical reports, and other sources. The intent of this compilation was to: (1) assemble, to the extent possible, all available and accessible publications relating to riparian management within a single source or document; (2) provide managers, field biologists, researchers, and others, a point of access for locating scientific literature relevent to their specific interest; and (3) provide, under one cover, a comprehensive collection of annotated publications that could dessiminate basic information relative to the status of our knowledge.
