The Everglades, a subtropical marshy region of Florida

Seeking restoration in this scenery

United States, April 3. (UITV) - Everglades National Park is a 1.5-million-acre wetlands preserve on the southern tip of the U.S. state of Florida. Often compared to a grassy, slow-moving river, the Everglades is made up of coastal mangroves, sawgrass marshes and pine flatwoods that are home to hundreds of animal species.

The Everglades is a natural region of tropical wetlands in the southern portion of the U.S. state of Florida, comprising the southern half of a large drainage basin and part of the neotropic ecozone.

The system begins near Oriando with the Kissimmee River, which discharges into the vast but shallow Lake Okeechobee. 

Human habitation in the southern portion of the Florida peninsula dates to 15,000 years ago. Before European colonization, the region was dominated by the native Calusa and Tequesta tribes.

The geology of South Florida, together with a warm, wet, subtropical climate, provides conditions well-suited for a large marshland ecosystem. Layers of porous and permeable limestone create water-bearing rock and soil that affect the climate, weather, and hydrology of South Florida.

About 300 million years ago, North America merged with Africa, connecting Florida with North America. Volcanic activity centered on the eastern side of Florida covered the prevalent sedimentary rock with igneous rock.

Everglades water scene

Surrounding the southern part of Lake Okeechobee is the Fort Thompson Formation, made of dense, hard limestone, shells, and sand. 

The geologic formations that have the most influence on the Everglades are the Miami Limestone and the Fort Thompson Formation.

As water leaves an area through evaporation from groundwater or from plant matter, activated primarily by solar energy, it is then moved by wind patterns to other areas that border or flow into the Everglades watershed system.

Evapotranspiration is responsible for approximately 70–90 percent of water entering undeveloped wetland regions in the Everglades.
