Aquatic Plant Research Invasives

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.

AIS Policy

DNR Science Services researchers contribute to science based decision making. They provide background research that helps policy makers make educated decisions as to how to regulate both current and future invasive species.



Invasives in Trade

One vector of invasive species introduction can be through the aquatic plant trade. Assessing the current availability of prohibited and restricted invasive species in the trade is an important step to guide education and outreach to prevent future introductions.



Management and Control

One important area of research for the DNR is the management and control of aquatic invasive species.



Understanding Invasives

In order to effectively manage, it is important to have a thorough understanding of how invasive species grow, reproduce and behave in their new environment.
