Floating islands

As well as cleaning the water, the native plants and grasses on the floating islands provide habitat for insects and birds. The roots below the waterline of the islands supply a rich food source to fish and minnows, provide shade and cover from predators and increase oxygen levels in the water which is beneficial for fish and other aquatic organisms.
