In moderate amounts, aquatic vegetation is beneficial to the natural ecosystem of most lakes and ponds. Reduce aquatic vegetation if it interferes with fishing, boating or swimming. Proper plant identification is necessary when considering aquatic vegetation control. Aquatic plant classification is based on growth form and location in the pond. Aquatic vegetation is found in most lakes and ponds and is beneficial to the natural ecosystem in moderate amounts.
Vegetation is needed for food production and cover for fish.
Aquatic plants produce oxygen, stabilize bottom sediment, protect the shoreline from wave erosion, and serve as feeding and nesting habitat for waterfowl. Aquatic vegetation can become so abundant it interferes with recreational use. When fishing, boating or swimming is seriously impeded, aquatic vegetation should be reduced. Periodic die-offs of dense vegetation also occur after periods of cloudy weather, long winter ice and snow cover, or the end of their growing season. Oxygen is consumed by bacteria that decompose dead plants.
