Book Description
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.
Current Issues in Alaska Wetland Management

Book Description
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.

Book Description
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.
Wetland Indicators
Author: Ralph W. TinerPublisher: CRC Press
ISBN: 1439853703
Category : Technology & Engineering
Languages : en
Pages : 631
Book Description
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.

Book Description
The impetus for this volume was the 2nd International Wetlands Conference which was held in June, 1984 at Trebon, Czechoslovakia. An overview of the worlds wetlands was one of the themes of the conference and it was decided that a useful follow-up would be a publication on the same topic. The initial goal was to cover as many of the worlds wetlands as possible in one volume and to have an emphasis on wetland ecology, biota, classification, and management. Individuals who made presentations at the Trebon confer ence were asked to prepare chapters and the editors also solicited other contributions. For a variety of reasons, the initial goal has been difficult to reach, especially coverage of the entire globe, and it has been necessary to publish the contributions in more than one volume. Volume 1 represents the com pletion of the first phase of the project and it covers most of the Western Hemisphere, Australia, most of Africa, the Indian subcontinent, the Mediter ranean region, and Papua New Guinea. Volume 2 will contain chapters on Western Europe, Northern Europe, Central Europe, most of northern and It is our hope that Volume western Asia, the Middle East, and Indonesia. 2 will appear in the near future and, if possible, a third volume will be published if authors can be secured to cover areas such as the Far East, other parts of the Indo-Pacific region, and New Zealand.
