Habitats and Wildlife

The Green Harbor River, and one of its major tributaries, Wharf Creek, flow through this property. The Green Harbor River finds its source in springs and ponds in Duxbury. It twists and turns through Marshfield via large cranberry bog complex, the Green Harbor Golf Club, the Daniel Webster Wildlife Sanctuary, property owned by the Marshfield Municipal Airport and Peter Igo Park. Just downstream of the Dyke Road bridge (and dike) it flows into the Atlantic Ocean at Green Harbor.
