Sudbury-Assabet-Concord River Watershed

Take Action

Invasive species cause many ecological problems. Though it seems daunting in some places, physically pulling invasives out of the ground or treating infestations with herbicides is the way we can restore “natural” ecosystem functions.

The first step, of course, is learning how to identify invasive plants. Refer to the Invasives pages for fact sheets and photos of our most common invasives, and for those that are just starting to arrive in the watershed.

Once you know how to identify invasives, Report them!

Then, get involved with members of the CISMA and get busy restoring the SuAsCo River Watershed!
