Natural Communities
 

As historian David McCully writes in The Everglades, "Although the surface of south Florida appears monotonously flat to the casual eye, it represents a complex of lilliputian valleys and plateaus to water." These differences in combination with variations in underlying rock and natural fire regimes created a diversity of natural communities within the Everglades ecosystem.

In geologic terms, the Everglades is young, only having formed within the last 5000 years. Rich black soil began forming and accumulating wherever sawgrass became the dominant vegetation. The black color is a product of the charcoal created frequent lightning-caused fires.

Management

"Currently, the metaphor 'river of grass' and the image of vast stands of saw grass that this metaphor suggests represent the historic Everglades in the minds of most Americans. The dominance of this metaphor is unfortunate and hinders restoration of the complex wetlands system it so imperfectly describes."
Historian David McCally

The tree islands north of I-75 were damaged during past droughts, when catastrophic wildfires burned native vegetation. Exotic plants, particularly Brazilian pepper, then invaded the sites. The Florida Fish and Wildlife Conservation Commission (FWC) is restoring many of these damaged tree islands by implementing a prescribed burning program to reduce fuel loading around the islands and to minimize wildfire damage during droughts and by controlling and removing exotic vegetation and re-vegetating with native plants. Bays, dahoon holly, and maple are planted in the interior, and Carolina willows and pond apples are planted around the edges of tree islands. The FWC is also providing the Army Corps of Engineers and the South Florida Water Management District with hydroperiod recommendations to protect tree islands in the future from excessive floods and droughts.
