Invasive Aquatic Plants

Eurasian Millfoil:

Eurasian watermilfoil negatively affects the water bodies it invades
in several ways. Due to its tendency to branch profusely and form a dense canopy over
the waters surface, it will shade out the native vegetation. This can alter the species
composition of the water which can result in a near monoculture of Eurasian
watermilfoil. This plant is not a valuable food source for waterfowl unlike some of the
native submersed aquatic plants. Plant biomass can become so dense that predator fish
will lose their foraging space and will be less effective at controlling prey species
resulting in an imbalanced fish community. Dense beds of Eurasian watermilfoil make
recreational activities such as boating, fishing and swimming nearly impossible.
