Great Dismal Swamp
From Wikipedia, the free encyclopedia
The Great Dismal Swamp is a marshy region on the Coastal Plain of southeastern Virginia and northeastern North Carolina between Norfolk, Virginia, and Elizabeth City, North Carolina in the United States. It is a southern swamp, the northernmost of many along the Atlantic Ocean's coast which includes the Everglades and the Big Cypress Swamp in Florida, the Okefenokee Swamp in Georgia, the Congaree Swamp and Four Holes swamps of South Carolina, and some of the Carolina bays in the Carolinas. Along the eastern edge runs the Dismal Swamp Canal, completed in 1805.
Essential to the swamp ecosystem are its water resources, native vegetative communities, and varied wildlife species. The Great Dismal Swamp's ecological significance and its wealth of history and lore make it a unique wilderness. It is one of the last large and wild areas remaining in the Eastern United States.
After centuries of logging and other human activities which were devastating the swamp's ecosystems, the Great Dismal Swamp National Wildlife Refuge was created in 1973 when the Union Camp Corporation of Franklin, Virginia donated 49,100 acres (200 km²) of land; the refuge was officially established through The Dismal Swamp Act of 1974.
The refuge consists of over 111,000 acres (500 km²) of forested wetlands. Lake Drummond, a 3,100 acre (13 km²) natural lake, is located in the heart of the swamp. Outside the boundaries of the National Refuge, the state of North Carolina has preserved and protected additional portions of the swamp, as the Great Dismal Swamp State Natural Area.

[edit] History
Scientists believe the Great Dismal Swamp was created when the Continental shelf made its last big shift. The whole swamp has peat underneath.
The origin of Lake Drummond, one of only two natural lakes in Virginia, is disputed. Scientists believe the lake could have been created by the impact of a meteoroid because it is oval shaped, looking like the impact of a meteoroid. They think it was made by a big meteoroid like the ones that are thought to have made the Carolina Bays. Other people believe it was made by a large underground peat burn about 3,500 to 6,000 years ago. Indian legend talks about "the fire bird" creating Lake Drummond.
People are not sure who discovered the Great Dismal Swamp but there is archaeological evidence which indicates human occupation began nearly 13,000 years ago.
By 1650, few American Indians remained in the area, and European settlers showed little interest in the swamp. In 1665, William Drummond, a future governor of North Carolina, was the first European to explore the lake which now bears his name. William Byrd II led a surveying party into the swamp to draw a dividing line between Virginia and North Carolina in 1728. George Washington visited the swamp and then formed the Dismal Swamp Land Company in 1763, which proceeded to drain and log off part of the area. A five-mile ditch on the west side of the current refuge there still bears his name. In 1805, the Dismal Swamp Canal began serving as a commercial highway for timber coming out of the swamp.
Before and during the American Civil War, the Great Dismal Swamp was a hideout for runaway slaves from the surrounding area. Some people believe there were at least a thousand slaves living in the swamp. This was the subject of Dred: A Tale of the Great Dismal Swamp, Harriet Beecher Stowe's follow-on to Uncle Tom's Cabin.
While all efforts to drain the swamp ultimately failed, logging of the swamp proved to be a successful commercial activity. Regular logging operations continued as late as 1976. The entire swamp has been logged at least once, and many areas have been burned by periodic wildfires. The Great Dismal Swamp has been drastically altered by humanity over the past two centuries. Agricultural, commercial, and residential development destroyed much of the swamp, so that the remaining portion within and around the refuge represents less than half of the original size of the swamp.
Before the refuge was established, over 140 miles of roads were constructed to provide access to the timber. These roads severely disrupted the swamp's natural hydrology, as the ditches which were dug to provide soil for the road beds drained water from the swamp. The roads also blocked the flow of water across the swamp's surface, flooding some areas of the swamp with stagnant water. The logging operations removed natural stands of baldcypress and Atlantic white cypress that were replaced by other forest types, particularly red maple. A drier swamp and the suppression of wildfires, which once cleared the land for seed germination, created ecological conditions that were less favorable to the survival of cypress stands. As a result, plant and animal variety decreased.
[edit] Preservation
In the mid 20th century, conservation groups from all over America began demanding that something be done to preserve what was left of the Great Dismal Swamp. In 1973, the Union Camp Company, a paper company based in Franklin, Virginia which had had large land property in the area since the beginning of the 20th century, donated just over 49,000 acres (198 km²) of its land to The Nature Conservancy, which transferred the property the following year to the U.S. Fish and Wildlife Service.
The Great Dismal Swamp National Wildlife Refuge was officially established by the U.S. Congress through The Dismal Swamp Act of 1974. The refuge consists of almost 107,000 acres (433 km²) of forested wetlands.
The primary purpose of the refuge's resource management programs is to restore and maintain the natural biological diversity that existed prior to the human-caused alterations. Essential to the swamp ecosystem are its water resources, native vegetation communities, and varied wildlife species. Water is being conserved and managed by placing water control structures in the ditches. Plant community diversity is being restored and maintained through forest management activities which simulate the ecological effects of wildfires. Wildlife is managed by insuring the presence of required habitats, with hunting used to balance some wildlife populations with available food supplies.
[edit] Today
The Great Dismal Swamp National Wildlife Refuge is located not only between two states, but also between two eco-regions, allowing for a wide range of plant and animal species. Baldcypress, tupelo, maple, Atlantic white cypress, and pine are the predominant tree species found on the refuge and support the wildlife within. Many mammal species, including black bear, bobcat, otter, and weasel along with over 70 species of reptiles and amphibians call the swamp home. More than 200 bird species can be seen at the swamp throughout the year, while 96 of those are known to nest on the refuge.
Lake Drummond is the middle of activity in the swamp today, though, with many fishermen, sightseers, and boaters. Tours of the Great Dismal Swamp canal are now only given by the passenger yacht, Bonny Blue.
