Aquatic plant communities provide many ecological benefits, such as food and habitat for waterfowl, fish, and other aquatic organisms. They also help maintain water quality by absorbing nutrients, providing oxygen, and reducing shoreline erosion. Aquatic plants contribute to the overall health of a waterbody, enhancing shoreline property values.

Many of the plants and animals found in a lake or other waterbody can be considered native to that water body — they have been in that system since it was created. When a plant or animal is introduced into a lake or pond from outside of that system or region, it is called a non-native species and may be invasive.

Aquatic invasive species (AIS) are non-native plants and animals that threaten native plants, wildlife, and their habitat. They also affect humans by degrading boating and fishing areas and reducing lake shore property values and tourism. Once AIS are established, eradication is almost impossible.

Lake George currently has six aquatic invasive species. To learn more about these six invasive species, please see the links to the left.
