MassBays National Estuary Program (MASSBAYS)

MassBays National Estuary Program

MassBays is an EPA National Estuary Program dedicated to protecting, restoring, and enhancing the estuarine resources of Massachusetts and Cape Cod Bays. We envision a network of healthy and resilient estuaries, sustainable ecosystems that support the life and communities dependent upon them. We facilitate partnerships to prompt local, state, and federal action and stewardship, convening stakeholders on the local and regional level, providing scientific basis for management decisions, and working with decision makers to identify problems and solutions.

Who we serve

The MassBays region covers over 1000 miles of coastline, from the tip of Cape Cod Bay to the New Hampshire border, and serves 50 coastal communities. With such a large area to cover, MassBays teamed up with three nonprofit organizations, an academic institution, and one Regional Planning Agency to host MassBays staff members. As a result, MassBays staff is working closely with communities to implement program goals and objectives in five coastal subregions: Upper North Shore, Lower North Shore, Metro Boston, South Shore, and Cape Cod.
