Duckweed is a free-floating invasive species with the potential to completely cover ponds thus disrupting oxygen levels and leading to fish kills. Light green in appearance, the very tiny plant has a single root-hair and 1 to 3 fronds only 1/16 to 1/8 inch long. Duckweed does provide a food source for waterfowl and fish as well as a habitat for fish and frogs. The seed bearing plant is typically found in still waters undisturbed by wave action.
