Everglades in the southeastern part of the state. Coined the River of Grass by the matriarch of the Everglades, Marjory Stoneman Douglas, the habitat is now considered on of the most imperiled in the country. Decades of attempts to drain the swamp and make it of some use to man has left the system in a dysfunctional state.
Freshwater marshes are generally wetlands with an open expanse of grasses and other
grass-like plants. Freshwater marshes generally contain few, if any,
trees and shrubs. Marshes have standing water for much of the year and
act as natural filters. As water passes over the marsh, water flow is
slowed down, and suspended particles settle out. Like the state's
freshwater swamps, water levels fluctuate in the marshes. From June
through September daily rains the marshes have standing water. From
October to December of January, when the rainfall amounts are very low,
the standing water gradually flows towards the coast or seeps into the
porous ground. By February and continuing through the end of May, many
marshes are completely dry. This makes them susceptible to fires.
