Tussocks and Floating Islands
Sometimes what appear to be islands rising out of the water are actually drifting masses of peat, mud, and plants. In extreme cases, these "islands," which range in size from a few feet across to hundreds of acres, can contain trees more than 50 feet tall and 8-12 inches in diameter. Though the following information pertains to tussocks and floating islands in Florida, these phenomena are world-wide, witnessed in such places as Argentina, Australia, Finland, India, Japan, Kenya, and Papua New Guinea. Aquatic plant managers call these islands tussocks, floating islands or floating forests. When freely drifting in Florida waterways, they can be extremely expensive in terms of property damage, lost income, and management costs.
