Download or read book ASSESSMENT OF WETLAND CONDITION AND WETLAND MAPPING ACCURACY IN UPPER BLACKS FORK AND SMITHS FORK UINTA MOUNTAINS UTAH written by Diane Menuz and published by Utah Geological Survey. This book was released on 2016-07-15 with total page 31 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Utah Geological Survey surveyed 28 sites in 2014 to quantify the location and condition of wetlands on the north slope of the Uinta Mountains in the Upper Blacks Fork and Smiths Fork watersheds. The three project goals were to compare accuracy of different wetland mapping techniques, assess wetland condition at randomly selected field sites, and develop a landscape model to predict wetland condition. Field mapping resulted in 6.2% and 13.1% less wetland area than mapping conducted by the National Wetland Inventory and the U.S. Forest Service, respectively. Sites were at or near pristine condition based on most field measures, though sites did show evidence of disturbance from grazing and non-native plant species. Landscape model results indicate that sites further from roads, closer to trails, and within the wilderness boundary generally had healthier plant community composition measures. While wetlands in the study area are overall in good condition, we recommend follow-up work to better quantify the impact of livestock grazing on wetlands in the area using study sites with well-understood levels of grazing intensity.
Download or read book Amphibian Declines written by Michael Lannoo and published by Univ of California Press. This book was released on 2005-06-15 with total page 1117 pages. Available in PDF, EPUB and Kindle. Book excerpt: This benchmark volume documents in comprehensive detail a major environmental crisis: rapidly declining amphibian populations and the disturbing developmental problems that are increasingly prevalent within many amphibian species. Horror stories on this topic have been featured in the scientific and popular press over the past fifteen years, invariably asking what amphibian declines are telling us about the state of the environment. Are declines harbingers of devastated ecosystems or simply weird reflections of a peculiar amphibian world? This compendium—presenting new data, reviews of current literature, and comprehensive species accounts—reinforces what scientists have begun to suspect, that amphibians are a lens through which the state of the environment can be viewed more clearly. And, that the view is alarming and presages serious concerns for all life, including that of our own species. The first part of this work consists of more than fifty essays covering topics from the causes of declines to conservation, surveys and monitoring, and education. The second part consists of species accounts describing the life history and natural history of every known amphibian species in the United States.
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.
