Download or read book Maine Wetlands and Waters Results of the National Wetlands Inventory written by U. S. Department of the Interior Fish and Wildlife Service and published by CreateSpace. This book was released on 2013-05-01 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: The NWI Program mapped about 2.04 million acres of wetlands and over 1 million acres of deepwater habitats, excluding marine waters. The wetland mapping is conservative due to limitations of the photointerpretation techniques employed. Considering NRCS hydric soil data and the results of a wetland map assessment done for the LURC region, the actual extent of wetlands in Maine is likely somewhere between 3.28 and 3.75 million acres, representing 17-19% of the state's land area.

Book excerpt: The U.S. Fish and Wildlife Service (FWS) has been conducting a nationwide survey of wetlands and deepwater habitats since the mid-1970s through its National Wetlands Inventory Program (NWI). This survey is accomplished using traditional photointerpretation techniques to produces map and digital geospatial data on the status of wetlands. The U.S. Geological Survey topographic maps serve as the base data upon which boundaries of wetlands and deepwater habitats are delineated.

Available in PDF, EPUB and Kindle. Book excerpt: The U.S. Fish and Wildlife Service established the National Wetlands Inventory (NWI) in the mid-1970s to map the nation's wetlands and deepwater habitats. Since then, the NWI has completed at least one phase of mapping for all northeastern states, except New York where roughly three-quarters of the state has been inventoried. For most areas, NWI maps have been converted to digital geospatial data which facilitates generation of acreage summaries of the NWI findings. State reports have been published for several states (Rhode Island, Connecticut, New Jersey, Delaware, and Maryland) and acreage summaries published for most other northeastern states. Since these reports were published, NWI data have been updated for many areas. This report summarizes current NWI data (as of September 2090) for each state from Maine through Virginia and the District of Columbia.

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.

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.
