What are Invasive (Nuisance) Aquatic Plants?
Aquatic plants are an important and beneficial part of lakes and rivers. However, some water plants, especially invasive non-native species that lack natural predators and diseases to keep their growth in check, can develop large nuisance populations. Some of the more common invasive aquatic plants in South Carolina include hydrilla, water hyacinth, giant salvinia, water primrose, phragmites, and alligatorweed.
