Aquatic Plant Research Aquatic Plant Research

Education and Outreach

As DNR Science Services researchers continue to learn more about Wisconsin’s aquatic communities, we share our findings with a variety of audiences across the state. We give oral and poster presentations at professional meetings as well as to local lake groups and other interested stakeholders and collaborators.


To successfully manage aquatic invasive species, it is important to understand their basic ecology and how they behave in Wisconsin waters. We also want to understand the invasion potential of species that may be introduced to Wisconsin in the future, and work to prevent their introduction.

Scientific Data on Aquatic Plant Communities

Aquatic plants play a vital role in the health of aquatic ecosystems. They provide food and shelter for fish and other wildlife; they help with excess nutrients and they prevent algae blooms. In order to make good decisions when managing Wisconsin's aquatic plant communities, we need to collect scientific information about aquatic plant communities using a standardized and comparable sampling method. This allows lake managers and researchers to make comparisons among lakes across space and time. Standardized methods help us better understand the outcomes of management actions. DNR Science Services helps answer questions about how to observe and study aquatic plant communities.

Understanding Aquatic Plants

Aquatic plants are an essential part of our lakes and rivers. They provide habitat for fish and invertebrates, stabilize sediments, and take up nutrients. Understanding what shapes aquatic plant communities leads to a better understanding of the health of Wisconsin waters.
