    Eurasian Water-Milfoil (Myriophyllum spicatum) Ecological Impacts. Eurasian milfoil can have strongly negative inpacts on native plant diversity and cover, especially in lakes with moderate to high nutrient levels (Nichols and Mori , Madsen ). Established colonies can easily expand into native plant communities, forming dense beds (> Weed Risk Assessment for Myriophyllum spicatum Ver. 1 3 1. Myriophyllum spicatum analysis Establishment/Spread Potential Myriophyllum spicatum is an aquatic plant that can survive shady conditions; low light conditions stimulate shoot and canopy growth of this species (Smith and Barko, ).
