Abstract: Embodiments of the invention provide a buoyant plant habitat for removing excess nutrients and other pollutants from a body of water and thereby remediating the water. The buoyant plant habitat may be used to remediate any suitable body of water, including ponds and lakes (both natural and manmade), streams and rivers, and stormwater, wastewater or drainage ponds. The buoyant plant habitat comprises a rigid, non-biodegradable grid structure into which a plurality of aquatic plants is placed. As the plants grow, they take up excess nutrients (nitrogen and phosphorous) and other pollutants from the water. From time to time, the top portions of the plants are removed by cutting. This cutting of the permanently removes the excess nutrients that have been taken up and stored by the cut portion of the plants. The cut plant matter may then be composted or otherwise disposed of.
