Sawgrass marshes are the characteristic association of the Everglades. Sparse sawgrass marshes occurs throughout the southern portion, especially along the periphery, while dense sawgrass covers much of the core. It accounts for 70 percent of the remaining Everglades landscape and is quite impressive. The plants may exceed 3 m in height and form an impenetrable mass. A common pattern identified in the Everglades is called strand and slough physiography alternating sawgrass and flag or water lily marshes.
Wet prairies require, the least frequently flooded hydroperiod, of any Florida marsh type.
The most prevalent species in the wet prairies are muhly, foxtail grass, black rush plume grass, whitetopped sedge, and love grass. The freshwater deep swamps of the southern Everglades are woody communities with water throughout most or all of the growing season. Classifications of deep water swamps found in the Everglades are known as Cypress Domes, Cypress Strands, and Dwarf Cypress. Cypress Strands are found primarily in south Florida, where diffused freshwater flows through a shallow forested depression on a relatively flat marsh or plain. The predominant tree of this type of ecosystem is the Bald Cypress.
