Approximate acreage: 9,240 acres
Watershed/subwatershed: Cape Cod/Pleasant Bay
Municipalities (% of ACEC): Brewster (<1%), Chatham (24%), Harwich (4%), and Orleans (72%)

The Pleasant Bay ACEC was nominated by the Conservation Commissions, Boards of Selectmen, and Planning Boards from the Towns of Brewster, Chatham, Harwich, and Orleans and was designated as an ACEC in 1987 because of the area’s extraordinary natural resources. The boundary for this ACEC generally follows a 100-foot buffer to the 10-foot contour line and includes wetlands and waterbodies that outflow into Pleasant Bay. Over 1,000 acres of salt marsh and several hundred acres of tidal flats are found in the ACEC. Other important habitats include islands, salt and freshwater ponds, rivers, bays, and barrier beaches. These areas provide flood control, storm damage prevention, improved water quality, wildlife habitat, and recreation opportunities to surrounding communities.
