7.3 New World Fire is an important element in the natural maintenance of the Everglades the majority of fires are caused by lightning strikes from thunderstorms during the wet season Their effects are largely superficial and serve to foster specific plant growth: sawgrass will burn above water but the roots are preserved underneath Fire in the sawgrass marshes serves to keep out larger bushes and trees and releases nutrients from decaying plant matter more efficiently than decomposition Whereas in the wet season dead plant matter and the tips of grasses and trees are burned in the dry season the fire may be fed by organic peat and burn deeply destroying root systems Fires are confined by existing water and rainfall it takes approximately 225 years for one foot (.30 m) of peat to develop but in some locations the peat is less dense than it should be for the 5,000 years of the Everglades' existence Scientists indicate fire as the cause; it is also cited as the reason for the black color of Everglades muck Layers of charcoal have been detected in the peat in portions of the Everglades that indicate the region endured severe fires for years at a time although this trend seems to have abated since the last occurrence in 940 BCE. 5.2 Annual traffic, QS 801-1000 New River, 9 Notes Transportation Natural hazards See also: List of notable crossings of the Atlantic Ocean. . Key West Historic District Precipitation during the wet season is primarily caused by air mass thunderstorms and the easterly flow out of the subtropical high (Bermuda High) Intense daytime heating of the ground causes the warm moist tropical air to rise creating the afternoon thundershowers typical of tropical climates 2:00 pm is the mean time of daily thundershowers across South Florida and the Everglades Late in the wet season (August and September) precipitation levels reach their highest levels as tropical depressions and lows add to daily rainfall Occasionally tropical lows can become severe tropical cyclones and cause significant damage when the make landfall across south Florida Tropical storms average one a year and major hurricanes about once every ten years Between 1871 and 1981 138 tropical cyclones struck directly over or close to the Everglades Strong winds from these storms disperse plant seeds and replenish mangrove forests coral reefs and other ecosystems Dramatic fluctuations in precipitation are characteristic of the South Florida climate Droughts floods and tropical cyclones are part of the natural water system in the Everglades.

Main article: Indigenous people of the Everglades region The formation of the Central American Isthmus closed the Central American Seaway at the end of the Pliocene 2.8 Ma ago the formation of the isthmus resulted in the migration and extinction of many land-living animals known as the Great American Interchange but the closure of the seaway resulted in a "Great American Schism" as it affected ocean currents salinity and temperatures in both the Atlantic and Pacific Marine organisms on both sides of the isthmus became isolated and either diverged or went extinct, University of Miami (private) The Everglades are a complex system of interdependent ecosystems Marjory Stoneman Douglas described the area as a "River of Grass" in 1947 though that metaphor represents only a portion of the system the area recognized as the Everglades prior to drainage was a web of marshes and prairies 4,000 square miles (10,000 km2) in size Borders between ecosystems are subtle or imperceptible These systems shift grow and shrink die or reappear within years or decades Geologic factors climate and the frequency of fire help to create maintain or replace the ecosystems in the Everglades.
