Aquatic Plants

Aquatic plants are an important part of any lake or pond. They provide food and protection for fish, waterfowl, insects, mammals and microscopic animals. These plants also help replenish oxygen to the aquatic environment, critical for the survival of fish and other aquatic organisms.

However, aquatic plants can also become a nuisance. Invasive plants that are not native to Michigan can grow rapidly out of control, choking out other plants and organisms and reducing recreational options in the lake.

Starry Stonewort

Starry stonewort is one example of an invasive plant seen in Michigan waters. Click here to learn more about starry stonewort from the Huron River Watershed Council.
