Mill City Park Invasive Removal

We’re tackling trash and invasive species in the upper Merrimack River watershed, and we need your help.

Across the watershed, we’re hosting a series of cleanup events to empower residents to have a hand in a cleaner future for the Merrimack River. We’ll take care of the details—all we need is your ethusiasum and a willingness to get outside.

Enjoy the fall weather, explore some beautiful NH park areas, and make the watershed a cleaner place.
