The Great Dismal Swamp
Transcript of The Great Dismal Swamp
Life in water and on land:
A healthy, complex hardwood wetland ecosystem, home to many important species, like the state-endangered canebrake rattlesnake.
Hydro electric plants:
The water has a tan- brownish color from tannic acid.
The swamp is flat with a high elevation of 25 feet. To the west is the Suffolk Scarp, a ridge about 50 feet high.
The pH is about the same annually, ranging between 3.5 and 4.0 mg/L. The acidic water is affected by rainfall almost bringing it up to neutral 7.0. A definite cause for the acidity is the tannic acid, giving the water a tan color. Another cause is the carbonic acid, sulfuric acid, and nitric acid.
Timber, agriculture features, fishing etc.
There is not many houses or company's around the swamp because it is secluded.
The mysteriously and formidably named great dismal swamp straddles the North Carolina-Virginia border only a few miles inland from the Atlantic coast.This region was referred to in correspondence as "Dismal Swamp" as early as 1715, and appears as Great Dismal Swamp on the 1733 Mosley map. The Great Dismal is a relatively young feature on the North American continent. Believed to be only about 10,000 years in age, the Great Dismal Swamp is wet, forested mantle of peat above a Pleistocene-era ocean bed. Once a vast morass over 2,000 square miles in size, it is now a hemmed in wilderness only a fraction of its original size, with approximately 175 square miles of it preserved as the Great Dismal Swamp National Wildlife Refuge.
There is no beginning to the Great Dismal Swamp, for it is a swamp not a river. But there are seven rivers that flow out of the Dismal Swamp, so the swamp is where they begin. The location of the swamp is in the Northeast corner of North Carolina and the southeast corner of Virginia.
One of the seven rivers that flow from the Great Dismal Swamp known as Pasquotank ends at the Albemarle sound where it empties itself.
High resistant to droughts. But the water level still do get lower that usual.
The Tannic acid in lake drummond makes the water inhospitable for any type of life including the vegetation that the birds eat. This is a direct result of the low bird population around that area. The high acid content does stop bacterial growth making the water drinkable.
Agriculture, 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.
There is 200 species of birds, 3 species of poisonous snakes, 18 non poisonous snakes, 56 species of reptiles, and there are mammals like otters, deer, bears, and racoons.
Swamps are forested wetlands. Like marshes, they are often found near rivers or lakes and have mineral soil that drains very slowly.
Animals commonly found in the Great Dismal Swamp include black bears, white-tailed deer, opossum, raccoons, cottonmouth snakes.
Unlike most swamps, it is not located near a river. It is a coastal plain swamp. Trees like cypress, black gum, juniper, and water ash are common.
Erosion of a sandstone formation created the Mountain lake on salt pond mountain. Phosphorous comes from most of the feeder streams. a large majority comes from Cayuga lake.
Tourists attractions help the business
boom around the swamp as the many
ecosystems intrigue a lot of people.
Streams that flow into the Great Dismal Swamp have some aquifers and watersheds.
The great dismal swamp is a large mix of habitats all which are rare. It contains some of the largest remaining white cedars and a potential habitat for the endangered red cockaded woodpecker. American alligators are only found in the Southeastern United States, from Great Dismal Swamp in North Carolina, south to Everglades National Park in Florida and west to the southern tip of Texas.
Great Dismal Swamp myths and legends:
The best known legend of the great dismal swamp is the lady of the lake. It was a myth formed by the poet Thomas Moore in 1803. The poems name is "the lake of the dismal swamp." It is based on a local legend about an indian bride who died before the wedding and she is seen paddling a white canoe across lake drummond. The poem tells of how sad the lover was and followed her ghost into the swamp and never came back.
