This report explains the problems with habitat degradation and destruction due to the invasion of exotic plants. Several exotic species including hydrilla, Eurasian watermilfoil, and waterhyacinth are discussed. Endangered and threatened plants are also discussed with the long-term goal of the removal of foreign plants in mind. The different means available to accomplish this goal are also outlined including herbicides (chemical methods) as well as alternative methods. The methods used are suppose to reduce nuisance plant populations while conserving rare species.
