Invasive plant expert Mike Bald lead a tour of Randolph's town forest between Prince Street and the Third Branch on Earth Day, Monday. Bald pointed out various invasive species throughout the forest, such as wild chervil, garlic mustard, and Japanese knotweed, which threaten native plants and can cause soil problems that lead to quicker erosion.
