The Buzzards Bay Coalition is a membership-supported non-profit organization dedicated to improving the health of the Buzzards Bay ecosystem for all through education, conservation, research and advocacy.
Buzzards Bay and its watershed face serious threats, including nitrogen pollution, oil spills and other forms of toxicity, increased development, and aging wastewater infrastructure. The various effects of climate change—rising sea levels, warming waters and fiercer storms—make the work harder and more important than ever.
Using a science-based approach, we conduct water quality and salt marsh monitoring throughout our watershed providing the most comprehensive insight into the state of our waters. We conserve and restore land to safeguard the region’s critical landscapes and waters. We also provide a range of meaningful outdoor activities at low or no cost to the public because we believe a direct connection to the Bay fosters environmental stewardship.
The long-term health of our local environment depends upon people knowing, loving and valuing Buzzards Bay and its watershed. To nurture environmental awareness, we encourage getting outside through outdoor programming for kids and adults. We also provide a digital information kiosk for all of the region’s outdoor areas and activities for anyone who’s interested in creating their own adventures.
It's your Bay, so get outside and enjoy over 200 places!
Join one of our upcoming Bay Adventures at our reserves, trails, rivers, and beaches.
Our centers provide a space for experiential learning and exploration across the watershed.
Dive into a week of paddling, sailing, swimming, and exploring Onset Bay!
We offer field trips for thousands of students and teachers every year.
Supporters, donors, and volunteers power the engine of the Coalition's work. Each year, hundreds of swimmers, runners and riders participate in our signature fundraising events to raise money in support of clean water. If you are interested in the Coalition's goals, we have a way for you to get involved.
