National Wildlife Refuge is a designation for certain protected areas of the United States managed by the United States Fish and Wildlife Service. The National Wildlife Refuge System is the system of public lands and waters set aside to conserve America's fish, wildlife and plants. Since President Theodore Roosevelt designated Florida's Pelican Island National Wildlife Refuge as the first wildlife refuge in 1903, the System has grown to over 560 national wildlife refuges and other units of the Refuge System, plus 38 wetland management districts encompassing more than . == Background == The mission of the Refuge System is to manage a national network of lands and waters for the conservation, management, and where appropriate, restoration of fish, wildlife and plant resources and their habitat. The Refuge System maintains the biological integrity, diversity and environmental health of these natural resources for the benefit of present and future generations of Americans. National Wildlife Refuges manage a full range of habitat types, including wetlands; prairies; coastal and marine areas; and temperate, tundra and boreal forests. The management of each habitat is a complex web of controlling or eradicating invasive species, using fire in a prescribed manner, assuring adequate water resources, and assessing external threats like development or contamination. Among these hundreds of national refuges are home to some 700 species of birds, 220 species of mammals, 250 reptile and amphibian species and more than 1000 species of fish. Endangered species are a priority of National Wildlife Refuges in that nearly 60 refuges have been established with the primary purpose of conserving 280 threatened or endangered species. National Wildlife Refuges are also places where visitors can participate in a wide variety of outdoor recreational activities. The National Wildlife Refuge System welcomes more than 45 million visitors each year, generating over $1.7 billion dollars and creating approximately 27,000 jobs for local economies. The Refuge System manages six wildlife-dependent recreational uses in accordance with the National Wildlife Refuge System Improvement Act of 1997, including hunting, fishing, birding, photography, environmental education, and interpretation. Hunters visit more than 350 hunting programs on refuges and on about 36,000 Waterfowl Production Areas. Opportunities for fresh or saltwater fishing are available at more than 340 refuges. There is at least one wildlife refuge in each of the fifty states. The National Wildlife Refuge System has employees who have a passion for conserving America's natural heritage. They exercise a wide range of skills in planning, biological monitoring and habitat conservation, contaminants management, visitor services, outreach and environmental education, heavy equipment operation, law enforcement, fire management and more. Opportunities are available for graduate and undergraduate students, as well as individuals at every level of the career ladder The National Wildlife Refuge System is dealing with such issues as urban intrusion/development, habitat fragmentation, degradation of water quantity and quality, climate change, invasive species, increasing demands for recreation, and increasing demands for energy development. The system has had numerous successes, including providing a habitat for endangered species, migratory birds, plants and numerous other valuable animals; implementation of the NWRS Improvement Act, acquisition and protection of key critical inholdings, and establishing leadership in habitat restoration and management. The agency has created Comprehensive Conservation Plans (CCPs) for each refuge, developed through consultation with private and public stakeholders. These began a review process by stakeholders beginning in 2013. The CCCPs must be consistent with the Fish and Wildlife Service (FWS) goals for conservation and wildlife management.〔National Wildlife Refuge System Improvement Act of 1997, 1997.〕〔United States Fish and Wildlife Service. "National Wildlife Refuge System: Refuge Planning- by Region",2010〕 The CCPs outline conservation goals for each refuge for fifteen years into the future, with the intent that they will be revised every fifteen years thereafter. The comprehensive conservation planning process requires several phases, including: a scoping phase, in which each refuge holds public meetings to identify the public’s main concerns; plan formulation, when refuge staff and FWS planners identify the key issues and refuge goals; writing the draft plan, in which wildlife and habitat alternatives are developed, and the plan is submitted for public review; revision of the draft plan, which takes into consideration the public’s input; and plan implementation.〔National Wildlife Refuge Association. "Comprehensive Conservation Plans"〕〔Cooperative Alliance for Refuge Enhancement (C.A.R.E.). "Comprehensive Conservation Plans: Coming to a Refuge Near You!", 2007〕 Each CCP is required to comply with the National Environmental Policy Act (NEPA) and must contain several potential alternatives to habitat and wildlife management on the refuge, and identify their possible effects on the refuge. Additionally, NEPA requires FWS planners and refuge staff to engage the public in this planning process to assist them with identifying the most appropriate alternative.〔 Comprehensive Conservation Plans are important documents for guiding wildlife and habitat management on national wildlife refuges. The completed CCPs are available to the public and can be found on the FWS website.〔〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「National Wildlife Refuge」の詳細全文を読む スポンサード リンク
