The Massachusetts Bays Program (Mass Bays) became part of the National Estuary Program (NEP) in 1990, highlighting the region as an “estuary of national significance.” Hosted by the Massachusetts Office of Coastal Zone Management , Mass Bays is dedicated to protecting, restoring, and enhancing the estuarine resources of Massachusetts and Cape Cod Bays. Mass Bays facilitates 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 educating decision makers about problems and solutions. Stretching from the New Hampshire border to the tip of Cape Cod, the 50 coastal communities in the Mass Bays region are home to over 1.7 million people. Due to its large size and geographic diversity, the Mass Bays area is divided into five regions. This regional approach ensures that Mass Bays' work is tailored to local environmental conditions based on stakeholder input, and supports regional priorities.
