Information on the location of the exotic plant: EURASIAN MILFOIL

Species Description

Eurasian milfoil is a submerged aquatic plant with whorled feather-like leaves that appear to have been clipped on the end. Eurasian milfoil can grow 12-15 feet tall, and exhibits a reddish shoot near the surface. It forms dense mats of tangled plants in lakes and ponds. Leaves have 12 or more pairs of leaflets.

General Information

Once introduced to a lake (usually by boats) it grows and spreads very quickly, ultimately ruining the ecology of the system, and value of shorefront property. There are three
