|Area||438,000 acres (1,770 km2)|
The Okefenokee Swamp is a shallow, 438,000-acre (1,770 km2), peat-filled wetland straddling the Georgia–Florida line in the United States. A majority of the swamp is protected by the Okefenokee National Wildlife Refuge and the Okefenokee Wilderness. The Okefenokee Swamp is considered to be one of the Seven Natural Wonders of Georgia. The Okefenokee is the largest "blackwater" swamp in North America.
Although folklore and many references state that the word okefenokee is a Native American word meaning "land of trembling earth," it is actually an anglicization of the Itsate Creek Indian words oka fenoke, which mean "water-shaking."  (More than a dozen variant spellings of the word have been documented in historical literature.) The swamp was designated a National Natural Landmark in 1974.
The Okefenokee was formed over the past 6,500 years by the accumulation of peat in a shallow basin on the edge of an ancient Atlantic coastal terrace, the geological relic of a Pleistocene estuary. The swamp is bordered by Trail Ridge, a strip of elevated land believed to have formed as coastal dunes or an offshore barrier island. The St. Marys River and the Suwannee River both originate in the swamp. The Suwannee River originates as stream channels in the heart of the Okefenokee Swamp and drains at least 90 percent of the swamp's watershed southwest toward the Gulf of Mexico. The St. Marys River, which drains only 5 to 10 percent of the swamp's southeastern corner, flows south along the western side of Trail Ridge, through the ridge at St. Marys River Shoals, and north again along the eastern side of Trail Ridge before turning east to the Atlantic.
Longtime residents of the Okefenokee Swamp, referred to as "Swampers", are of overwhelmingly English ancestry. Due to relative isolation, the inhabitants of the Okefenokee used Elizabethan phrases and syntax, preserved since the early colonial period when such speech was common in England, well into the 20th century. The Suwannee Canal was dug across the swamp in the late 19th century in a failed attempt to drain the Okefenokee. After the Suwannee Canal Company's bankruptcy, most of the swamp was purchased by the Hebard family of Philadelphia, who conducted extensive cypress logging operations from 1909 to 1927. Several other logging companies ran railroad lines into the swamp until 1942; some remnants remain visible crossing swamp waterways. On the west side of the swamp, at Billy's Island, logging equipment and other artifacts remain of a 1920s logging town of 600 residents. Most of the Okefenokee Swamp is included in the 403,000-acre (1,630 km2) Okefenokee National Wildlife Refuge.
A wildfire begun by a lightning strike near the center of the refuge on May 5, 2007, eventually merged with another wildfire that began near Waycross, Georgia, on April 16 when a tree fell on a power line. By May 31, more than 600,000 acres (2,400 km2), or more than 935 square miles, had burned in the region.
The Okefenokee Swamp Alliance is a conservation group that works for the continued preservation of the swamp.
There are four public entrances:
- Suwannee Canal Recreation Area at Folkston, Georgia
- Kingfisher Landing at Race Pond, Georgia
- Stephen C. Foster State Park at Fargo, Georgia
- Suwannee Sill Recreation Area at Fargo, Georgia
The graded Swamp Perimeter Road encircles Okefenokee National Wildlife Refuge. Gated and closed to public use, it provides access for fire management of the interface between the federal refuge and the surrounding industrial tree farms.
Many visitors enter the Okefenokee National Wildlife Refuge each year. The swamp provides an important economic resource to southeast Georgia and northeast Florida. About 400,000 people visit the swamp annually, with many from distant locations such as Germany, the United Kingdom, France, Japan, China and Mexico. Service providers at the refuge entrances and several local outfitters offer guided tours by motorboat, canoe, and kayak.
DuPont titanium mining operation
A 50-year titanium mining operation by DuPont was set to begin in 1997, but protests and public–government opposition over possibly disastrous environmental effects throughout 1996–2000 forced the company to abandon the project in 2000 and retire their mineral rights forever. In 2003, DuPont donated the 16,000 acres (65 km2) it had purchased for mining to The Conservation Fund, and in 2005, nearly 7,000 acres (28 km2) of the donated land was transferred to Okefenokee National Wildlife Refuge.
The Okefenokee Swamp is part of the Southeastern conifer forests ecoregion. Much of the Okefenokee is a southern coastal plain nonriverine basin swamp, forested by bald cypress (Taxodium distichum) and swamp tupelo (Nyssa biflora) trees. Upland areas support southern coastal plain oak domes and hammocks, thick stands of evergreen oaks. Drier and more frequently burned areas support Atlantic coastal plain upland longleaf pine woodlands of longleaf pine (Pinus palustris).
The Okefenokee Swamp is home to many wading birds, including herons, egrets, ibises, cranes, and bitterns, though populations fluctuate with seasons and water levels. The swamp also hosts numerous woodpecker and songbird species. Okefenokee is famous for its amphibians and reptiles such as toads, frogs, turtles, lizards, snakes, and an abundance of American alligators. It is also a critical habitat for the Florida black bear.
In 1974, two recordings of the sounds of the swamp were released as disk 6 of the Environments LPs.
More than 600,000 acres (2,400 km2) of the Okefenokee region burned from April to July 2007. Essentially all of the swamp burned, though the degrees of impact vary widely. Smoke from the fires was reported as far away as Atlanta and Orlando.
Four years later. in April 2011, the Honey Prairie wildfire began when the swamp had been left much drier than usual by an extreme drought. As of January 2012, the Honey Prairie fire had already scorched more than 315,000 acres (1,270 km2) of the 438,000-acre (1,770 km2) Okefenokee, sending volumes of smoke across the southern Atlantic seaboard and with an unknown impact on wildlife. With the drought still continuing, the massive Honey Prairie fire continued[when?] to burn at only 75% containment.
On April 17, 2012, the Honey Prairie Fire was declared out. Thousands of firefighters, refuge neighbors and businesses contributed to the safe suppression of this fire. At the peak of fire activity on June 27, 2011 the Honey Prairie Complex had grown to 283,673 acres and had 202 engines, 112, dozers, 20 water tenders, 12 helicopters, and 6 crews with a total of 1,458 personnel assigned. Over the duration of the fire, there were no fatalities or serious injuries. Firefighters did an excellent job containing the fire within the boundaries of the 402,000 acre Okefenokee National Wildlife Refuge. Only 18,206 acres burned outside the refuge
