Aquatic plants provide useful habitat for fish, invertebrates, aquatic mammals, and birds. However, too much vegetation in a lake or pond can interfere with boating, fishing, swimming, and other recreational activities. It can also hinder water movement, affect fish populations, and in some cases, reduce water quality. In general, exotic plants are more likely to cause problems than native species, and control measures may be necessary.
