Non-native plants have invaded most of the Mill River’s bed and banks, presenting a significant problem by crowding out native species and creating eye-sores. One prime example is Japanese knotweed (Polygonum cuspidatum), which suppresses other plants, creates impenetrable “knotweed hells,” and obscures our view of the river in many reaches.
MRGI has partnered with Smith College, the New England Wild Flower Society, and several other groups to develop a strategic plan for invasive plant management. As part of that process the group has developed a handy guide to Invasive Species management in the Mill River watershed.
