Invasive Species --
A New Brunswick Concern

​

Eurasian water-milfoil (Myriophyllum spicatum) is present in the Madawaska River and throughout the Saint John River.

This submersed aquatic plant creates dense mats that interfere with recreational activity. It out-competes native plants which negatively impacts our fish and wildlife. This invasive plant can spread when fragments cling to boats, motors and trailers and are moved to new areas. Please do not pass through mats of vegetation and follow the guidelines below when moving from one waterbody to another.

 

(Note: Some water-milfoils are native to New Brunswick.)
