Aquatic Plant Research Management and Control

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

Eurasian Watermilfoil (EWM) Control

Eurasian watermilfoil is an invasive species that is found across the state. In some waterbodies where it is found, there is a desire to control the growth of this plant. DNR Science Services are investigating multiple control methods in order to determine both efficacy and possible unintended effects.



Managing Lakes

Once an invasive species has become established in a lake, it is important to manage the lake effectively. Providing information on control options to lake residents and lake managers helps guide appropriate management actions.
