The floating island was created to mimic nature; help improve water quality, including reducing phosphorus levels; and buffer habitats against surges in nutrients and pollution. Buoyancy in artificial floating reedbeds is commonly provided by polyethylene or polyurethane foam, or polyethylene plastic containing air voids. Growth media include coconut fibre; mats made of polyester or recycled PET bottles; synthetic geotechnical mat; jute; soil; and sand. Artificial floating islands are sometimes made by planting cattails and other plants on floating plastic rafts in order to reduce phosphorus levels in the water. In Cleveland's Cuyahoga River floating rafts were made to restore fish populations.
