Everglades [SEP] Sawgrass marshes and sloughs
Several ecosystems are present in the Everglades, and boundaries between them are subtle or absent. The primary feature of the Everglades is the sawgrass marsh. The iconic water and sawgrass combination in the shallow river long and wide that spans from Lake Okeechobee to Florida Bay is often referred to as the "true Everglades" or just "the Glades". Prior to the first drainage attempts in 1905, the sheetflow occupied nearly a third of the lower Florida peninsula. Sawgrass thrives in the slowly moving water, but may die in unusually deep floods if oxygen is unable to reach its roots. It is particularly vulnerable immediately after a fire.
