The Florida Everglades — A Wetlands Ecosystem
The Everglades, a vast wetlands ecosystem made up of marshes and swamps, begins at Lake Okeechobee, a large lake in the center of Florida, and ends in the Gulf of Mexico and Florida Bay. It is nearly 50 miles across and 110 miles long (Hinrichsen), and when viewed from the air, appears to be miles and miles of shallow water flowing through thick mats of grass. This perception has earned it the name “River of Grass”. Although it does flow like a river, the flow is so incredibly slow that, from a distance, it doesn’t seem to move at all.
All of the wildlife in the Everglades is totally dependent on the cycling of water. One example of this dependence is the feeding relationship between the snail kite (an endangered bird species), and the apple snail (a freshwater mollusk the size of a golf ball) (Talley). The apple snails reproduce during the rainy season. When water levels are at their highest, they lay thousands of tiny pink eggs on the stalks of marsh grasses. As the water recedes, the snail kites fly all over the Everglades looking for them. Once they find them, they swoop down and use their specialized beaks to pluck the tender snails from their shells. The water cycle and the lives of apple snails and snail kites are intertwined. Snail kites depend on the successful reproduction of apple snails, which is, in turn, affected by the amount of rainfall. Only recently have scientists been able to observe how close this relationship is. When humans drained large areas of the Everglades and converted them to agricultural lands, the population of apple snails decreased sharply. This had a dramatic effect on the snail kite population. In 2003, only 1600 snail kites remained in Florida, the bird's only U.S. habitat (Smith). The relationship among humans, snail kites, and apple snails illustrates the delicate balance of nature in an ecosystem. When humans alter the water cycle, they directly affect the food chain.
Alligators are animals that often come to mind when people think of the Everglades. The American alligator, once a highly endangered reptile, plays a critical role in the Everglades ecosystem, especially during the dry season (Alligator Holes). As winter approaches, water levels begin to drop. Alligators, which need an ample supply of water to survive, sense the changing of the season and begin to prepare ...

Invasive species have the potential to harm their new environments. The release of Burmese pythons in South Florida is especially troublesome because the subtropical climate and the vast undisturbed habitats of the Everglades enable the species to thrive. Other large non-native snakes— such as the common boa (Boa constrictor), green anaconda (Eunectes murinus), yellow anaconda (Eunectes notaeus), and reticulated python (Python reticulatus)—have been observed in the wild in South Florida, but only Burmese pythons and common boas are known to be breeding. Burmese pythons were first reported as established in Everglades National Park (ENP) by Meshaka, based in part on specimens collected on the Main Park Road in the mid-1990s. Since then, the number of Burmese pythons captured or found dead in and around ENP has increased dramatically increased. From 2002 - 2005, 201 pythons were captured and removed or found dead. In 2006 - 2007 alone, that number more than doubled to
This is a very critical situation that needs to be fixed urgently. The habitats of the Everglades depend on an annual water cycle which has been hindered by the development construction which was imposed on the farmland. Back in the 19th century, developers were keen on draining all the swamps in the Everglades for developmental purposes. Their intention was to grow sugarcane plantations on the land yet sugarcanes are highly destructive to the Everglades. They too disrupt the water cycle to which the wildlife has adapted. The Florida sugar industry built on the southern Shore of Lake Okeechobee directly clocks the water source for the remaining Everglades hence destroying the habitats of the wildlife existing in the affected areas.
Nature designed Florida to be one large marine ecosystem. Florida is one big sand peninsula located below the 40th longitudinal North American line. Three bodies of salt water (Gulf of Mexico, Strait of Florida and Atlantic Ocean) surround three out of four directions of Florida. Man-made canals, natural lakes, rivers and estuaries are confined within the State of Florida’s physical boundaries. All of these form an interlocking system of waterways that impact the interconnected marine environment (marine ecosystem). All of Florida’s waterways are connected back to the surrounding bodies of water while passing through Florida’s sub-tropical and temperate zones and impact the delicate marine ecosystem balance. Man and nature are causing a negative impact to this region like never before. Hurricanes, lack of green initiatives, garbage, pollution and the stripping of natural resources for population growth are decimating Florida’s natural ecosystems.

The efforts taking place through different conservation organizations and the State of Florida are making a mixed impact on the survival of Manatees and Sea Turtles. The decline in manatee population has decreased, but due to low reproduction rates, more needs to be done to avoid extinction. The sea turtle outlook is more species specific. Some species of turtle are seeing stabilization in population, while others are not. The State of Florida has a large array of custom license tags that support the conservation efforts taking place within the State. The proceeds go to benefit the local marine life in Florida. With financial resources, state and local cooperation, and through constant research and observation, we are able to learn more about both of these gentle animals. With human awareness of those living in Florida, these two animals will survive
such changes as well as stop the introduction of exotic plant-life and animals into the Everglades.
The Florida Everglades have been slowly and steadily diminishing in size for over many decades. Throughout the years, the Everglades have had an abundant, healthy environment. The massive swamps were once rich with marshland, and had ecosystems chock-full of wildlife. However, due to large corporations, natural disasters and most importantly, the growth of the human population, the Everglades are 50% smaller than they were hundreds of years ago. The destruction of the Florida Everglades includes not only a diminishing number of the marshland, but also the lessening of wild life, such as alligators, herons, and exotic plants. While there is a government plan set for the restoration of the everglades, it will take many years to make up for the
The Everglades, classified as a wetland or a "transition zone" can support plant and animal life unlike any other place. Wetlands are an important resource for endangered species and "that more than one third of the United States' threatened and endangered species live only in wetlands." Says Elaine Mao, the author of Wetlands and Habitat Loss. People have started to notice the importance and the role of wetlands like the Everglades and how they are valuable and essential for ecosystems to live. Wetlands provide so many kinds of plants, mammals, reptiles, birds, and

Everglades National Park is sanction to some of the most exceptional animal and plant ecosystems. From the tall, sunny rock pinelands to the humid, lush hardwood hammocks to the tropical, sawgrass marsh, the everglades is believed to be one of the most diverse and astonishing ecosystems in the United States. Sounds of birds tickle your eardrums, beautiful flowers bloom in the radiant morning sun, animals graze peacefully as they go about their day in their natural habitat. It is a breath taking sight and the most popular place for sightseers to go observe the wildlife or kick back and relax and take in the soothing fresh air.
The Spanish had great expectations of Florida despite disastrous results from expeditions such as Ponce de Leon and Lucas Vazquez de Ayllon's. In a description of the panhandle region from Hernando de Soto's campaigns, Gonzalo Fernandez de Oviedo wrote, “The Province of Apalache is very fertile and abundantly provided with much corn, kidney beans, pumpkins, various fruits, much venison, many varieties of birds and excellent fishing near the sea.” Notwithstanding the environmental benefits, the Spanish were ultimately unsuccessful in establishing a plantation economy in Florida. Both the British and the proto-Seminoles achieved greater success in establishing a plantation economy after the failure of the Spanish. Many factors contributed to the success of the proto-Seminoles and British in Florida including increased population, choice of economy, and African presence in Florida.
Florida became a state in 1845 and almost immediately people began proposing to drain the Everglades. In 1848, a government report said that draining the Everglades would be easy, and there would be no bad effect. Canals and dams were dug to control seasonal flooding. Farmers grew vegetables in the rich soil of the drained land, Ranchers had their cattle graze on the dry land, and new railways lines were constructed to connect communities throughout south Florida; but the ecosystem of the Everglades was not suited for either farming or ranching. The natural cycle of dry and wet seasons brought a devastating series of droughts and floods. These had always been a p...
...n, the Louisiana wetlands are an extremely valuable asset to the State of Louisiana and the United States. The continual loss of Louisiana wetlands has the potential to have an immensely negative effect on the economy at a state and national level. Over 2 million people live in the Louisiana coastal parishes (Field et al., 1991). The majority of people living on the Louisiana coast make their living from things that are directly related to the wetlands. The Louisiana wetlands make up the largest wetland community in America and is being lost at a rate greater than the other wetland communities in the country. The suggested strategies that are being taken into consideration could be helpful but it seems that the State of Louisiana is not as concerned as it should be given the future consequences and much like climate change coastal erosion is not being taken serious.
