Eurasian water-milfoil is a species of aquatic exotic invasive plants (AEIP) native from Eurasia that is now well established in Quebec. Its progression is in constant evolution. In 2016, in the Laurentians, it presence was signaled in over forty lakes.
Recreational activities such as fishing, canoeing and swimming can be limited by the infestation of AEIP. The multiplication of AEIP can also affect negatively the value of lakeshore properties.
