Belle Isle Marsh and its tributary span over 300 acres across East Boston, Revere, and Winthrop at the mouth of Boston Harbor. The last remnant within Boston of the salt marshes, the reservation hosts over 250 species of birds, including seven listed species, who spend some or all of their life cycles there. In recognition of this important habitat the U.S. Fish and Wildlife Service recognizes Belle Isle Marsh as one of Massachusetts’ most biologically significant estuaries north of Boston and the National Audubon Society recognizes it as an Important Bird and Biodiversity Area, an international designation.
MyRWA was recently awarded a Healthy Estuaries grant to conduct an inventory of environmental conditions in Belle Isle Marsh, the first step toward developing a comprehensive resource management plan for this area.
