The Florida Everglades Essay -- Geology

THE EVERGLADES: RIVER OF GRASS The Everglades, also known as the River of Grass, is one of South Florida's most treasured areas. It is an area still full of wonder and mystery. The Everglades is lined with a specific type of limestone bedrock formed by tiny organisms called byrozoans. These animals, though not related to coral, act like coral by extracting dissolved limestone from the sea water around them and using it to construct protective chambers in which to live. They then attach to various kinds of sea grasses on the ocean floor and coat them as well. Individual chambers combine together to form rock-like structures. Over thousands of years, when South Florida was completely submerged, a vast amount of this limestone combined with other ocean sediments and was laid down over the area now covered by the Everglades. Prior to the draining activities of humans and its use as an agricultural area, the Everglades was flooded about nine to eleven months of the year. It also lost only about 0.03 inches of soil per year. After the drainage the Everglades began losing soil at approximately 1 inch per year. Now, however, it is only losing 0.56 inches per year. In the Everglades there are a variety of different animals and species that seem to be able to thrive in the same habitat. The truth is that due to elevation differences, and therefore differences in the water level, the Everglades is really an area of interconnecting, but different habitats. One of the more important habitat areas is actually created by one of the Everglades most famous inhabitants – the alligator. The alligators move in and out of holes (depressions) in the limestone described above. By doing this they keep this area lower than the rest ... ...restore natural lands. The federal, state, and local governments are joining forces to bring these pristine natural lands back to their original splendor and beauty. "The question of why we should protect the Everglades has now evolved into how we should restore the Everglades," according to Suzie Unger. "Everglades National Park is the largest remaining sub-tropical wilderness in the continental United States and has extensive fresh and saltwater areas, open Everglades prairies, and mangrove forests. Abundant wildlife includes rare and colorful birds, and this is the only place in the world where alligators and crocodiles exist side by side. The park is 1,506,539 acres (606,688 hectares) in size. It is a World Heritage Site, an International Biosphere Reserve, and a Wetland of International Significance," according to the following website: http://nps.gov/ever
