This page still needs much more updating, but we currently have some wonderful material to look at, such as the Smith College invasive guide booklet that Gaby Immerman, the staff at the New England Wild Flower Society, and Smith College students produced. It's an invaluable handbook of 16 of the most harmful exotic invasive plants along the Mill River, describing the plants and suggesting management methods to control each of them.
