Diversity of life forms of the everglades

Its ecosystems are in constant flux as a result of the interplay of three factors: The South Florida climate was once arid and semi-aridinterspersed with wet periods. Fresh water saturated the limestoneeroding some of it and creating springs and sinkholes.

The abundance of fresh water allowed new vegetation to take root, and through evaporation formed thunderstorms. Limestone was dissolved by the slightly acidic rainwater. The limestone wore away, and groundwater came into contact with the surface, creating a massive wetland ecosystem.

The Everglades are unique; no other wetland system in the world is nourished primarily from the atmosphere. Kissimmee River outlets flow into Lake Okeechobee, which sits 18 feet 5.

The gradient change is so slight that the river moves only 2 feet 0.

The peninsula has been covered by sea water at least seven times since the earliest bedrock formation. Fossilized bryozoans and tiny shells, or ooidsmake the limestone porous. Water is stored in the rock, sometimes from one year to the next. Shorter hydroperiods of three or four months promote the growth of periphyton: In areas with hydroperiods of longer than nine months, peat builds up over hundreds or thousands of years due to many generations of decaying plant matter.

Peat and marl are considered nutrient-poor soils that foster the growth of specialized vegetation depending on the length of the regional hydroperiod.

Five types of peat appear in the Everglades system; each type supports a specific type of vegetation, such as sawgrass, tree islands, or custard apple trees. Once peat buildup reaches the surface, oxygen reacts with the microorganisms to decay the peat rapidly in a process called subsidence.

Initial attempts at developing agriculture near Lake Okeechobee were successful, but the nutrients in the peat quickly deteriorated by drying, and were broken down by bacteria in the soil. The dried peat burned or was degraded into carbon dioxide and water by microorganisms.

Some homes built near early farms had to restructure their foundations on stilts as the peat deteriorated; other areas lost approximately 8 feet 2.

Most of that loss occurs in the Everglades Agricultural Area; the least amount of loss is found in Everglades National Park.

The majority are caused by lightning strikes from thunderstorms during the wet season. Their effects are largely superficial, and serve to foster further plant growth: Fire in the sawgrass marshes serves to keep out larger bushes and trees, and releases nutrients from decaying plant matter more efficiently than decomposition.

The only impediment to the spread of fire in the Everglades is the presence of water. Scientists point to fire as the reason.

Dry-season fires are rarer due to the lack of lightning, but their damage may be more pervasive. Fires in this cycle may be numerous and have little effect, or rare and have catastrophic consequences.

The third cycle appears in a year frequency associated with severe drought. Layers of charcoal have been detected inside peat in parts of the Everglades, indicating the region endured severe fires for years at a time, although this trend seems to have abated since the last occurrence around BCE.

Geological Survey The Everglades are dominated by sawgrass in water; this is the titular "River of Grass" popularized by Marjory Stoneman Douglas in This river contains a wide variety of plant and animal life.

An early American environmentalist named Gifford Pinchot said of the Everglades, "It is a region so different that it hardly seems to belong to the United States. It is full of the most vivid and most interesting life on land, in the air, and in the water.

It is a land of strangeness, separate and apart from the common things we all know so well. Some authors refer to the sawgrass and water combination as the "true Everglades" or just "the Glades".

Sawgrass marsh[ edit ] Most marshes in the Everglades are dominated by the sedge known as Cladiumor sawgrass in common terminology. The sedge is a three-dimensional v-shaped stalk with upward-pointing teeth.

Sawgrass thrives in the slowly moving water, but may die if oxygen is unable to reach its roots and is particularly vulnerable to floods immediately after a fire. Farther south, where the peat is not as rich, it typically grows 4 feet 1. In shorter hydroperiods, marl may form instead of peat.Welcome to Everglades National Park.

Welcome to Everglades National Park. national park System. Thirteen years later, through a combination of federal, state and private lands, a vast wetland teeming with life was dedicated as a national park. Everglades was the first national park preserved primarily for its abundance and variety of life.

Oct 19,  · Genetic diversity is the variation of heritable characteristics present in a population of the same species.

It serves an important role in evolution by allowing a species to adapt to a new environment and to fight off parasites. Restoration of Everglades In: Science Submitted By ritikapoddar11 Descriptions of Diversity of Life Forms A. Existing Preservations and Protections of Life Forms A.

Central Figures for Conservation B. Enactment of Laws to Protect. There are a wide variety of birds of prey living in the Florida Everglades. These birds hunt other birds, small mammals, reptiles, amphibians insects and fish. Because of the diversity of wild life found in the Florida Everglades it supports many different types of birds of prey, also know as raptors.
