The Okefenokee National Wildlife Refuge is a 402,000‑acre (1,627 km2) National Wildlife Refuge located in Charlton, Ware, and Clinch Counties of Georgia, and Baker County in Florida, United States. The refuge is administered from offices in Folkston, Georgia. The refuge was established in 1937 to protect a majority of the 438,000 acre (1,772 km2) Okefenokee Swamp.〔Federal Register Volume 70, No. 147, pp. 44355–44357 - Tuesday August 2, 2005〕〔U.S. Fish and Wildlife Service, (Okefenokee National Wildlife Refuge ), URL retrieved June 15, 2006〕 The name "Okefenokee" is a Native American word meaning "trembling earth." 〔U.S. Fish and Wildlife Service, (Refuge Overview ), ''Okefenokee National Wildlife Refuge'', .pdf, URL retrieved June 15, 2006〕 A wildfire which began with a lightning strike near the center of the Refuge on May 5, 2007 eventually merged with another wildfire which had begun near Waycross, Georgia on April 16 due to a tree falling on a power line. By May 28, more than had burned in the region, or more than 900 square miles (2300 km2). () () Nearly 400,000 people visit the refuge each year, making it the 16th most visited refuge in the National Wildlife Refuge System.〔 It is the largest in acreage of any that is not located in a western state. In 1999, the economic impact of tourism in Charlton, Ware, and Clinch Counties in Georgia exceeded $67 million.〔 The refuge has a staff of 16 with a fiscal year 2005 budget of $1,451,000.〔 The refuge also administers the Banks Lake National Wildlife Refuge. ==History== The swamp has a rich human history including Native American settlement, explorations by Europeans, a massive drainage attempt, and intensive timber harvesting. Native Americans inhabited Okefenokee Swamp as early as 2500 BC.〔(http://www.fws.gov/okefenokee/refugehistory.htm )〕 Peoples of the Deptford Culture, the Swift Creek Culture and the Weeden Island Culture occupied sites within the Okefenokee.〔 The last tribe to seek sanctuary in the swamp were the Seminoles.〔 Troops led by General Charles R. Floyd during the Second Seminole War, 1838–1842, ended the age of the native Americans in the Okefenokee.〔 The Suwanee Canal Company purchased 238,120 acres (963 km2) of the Okefenokee Swamp from the State of Georgia in 1891 to drain the swamp for rice, sugar cane, and cotton plantations.〔 When this failed, the company began industrial wetland logging as a source of income.〔 Captain Henry Jackson and his crews spent three years digging the Suwannee Canal 11.5 miles (18.5 km) into the swamp.〔 Economic recessions led to the company’s bankruptcy and eventual sale to Charles Hebard in 1901.〔 Logging operations, focusing on the cypress, began in 1909 after a railroad was constructed on the northwest area of the swamp.〔 More than 431 million board feet (1,020,000 m3) of timber were removed from the Okefenokee by 1927, when logging operations ceased.〔 The ''Okefenokee Preservation Society'', formed in 1918, promoted nationwide interest in the swamp.〔 With the support of State and local interests and numerous conservation and scientific organizations, the Federal Government acquired most of the swamp for refuge purposes in 1936.〔 In 1937, with Executive Order 7593 (later amended by Executive Order 7994), President Franklin Delano Roosevelt established the refuge, designating it as "a refuge and breeding ground for migratory birds and other wildlife." 〔 The establishment of Okefenokee Refuge in 1937 marked the culmination of a movement that had been initiated at least 25 years earlier by a group of scientists from Cornell University who recognized the educational, scientific, and recreational values of this unique area.〔 In 1974, to further ensure the protection of this unique ecosystem, the interior sections of the refuge were designated a National Wilderness Area.〔 In 1986, the Okefenokee Refuge was designated by the Wetlands Convention as a Wetland of International Importance.〔 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「Okefenokee National Wildlife Refuge」の詳細全文を読む スポンサード リンク
