Invasive aquatic plants are generally defined as nonnative plant species that cause ecological and/or economic harm to natural or managed ecosystem. Invasive plants can greatly reduce the desired native plant growth. They can form dense canopies on the surface of the water which will result in a dramatic change in the quality of habitat for fish as well as interfering with desired use of the water (ex; boating, swimming, fishing, irrigation, fire suppression systems which are tied to the body of water).
