Natural History

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.  In this part of our website you’ll find and be able to contribute information on the river’s birds, animals, and fish.  You’ll want to check out the rocks and landforms of our home, and there’s plenty of room for botanizing.


Smith horticulturist Gaby Immerman, the staff at the New England Wild Flower Society, and Smith College students produced an invaluable handbook of 16 of the most harmful exotic invasive plants along the Mill River.  It describes the plants and suggests management methods to control each of them.  Smith College invasive guide booklet.


Check out the natural treasures of the Mill River and add your favorite to the list.

We’ll be using this section, as well, to improve the health of our river and its biota.  In particular, there will be pages dealing with invasive plant species and monitoring the river’s water quality.  In time, we hope to spin off a “Stream Team” to protect and restore our waters:  Our Massachusetts Stream Team leader, Carrie Banks, has an office right in Haydenville.
