Natural Treasures

The Mill River corridor holds an extraordinary array of plant and animal life in our 52-square mile watershed and it contains the geological narrative of how this place came to be.

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.  Smith College invasive guide booklet.
