North Hill Marsh can best be described as a sanctuary within a refuge. Situated within Duxbury’s Eastern Greenbelt, 1,000 acres of contiguous open space, the sanctuary’s oak and pine woodlands, wetlands, and 90-acre pond provide habitat for wildlife, especially migratory waterfowl. A clearly marked trail system circles the pond and travels through Duxbury Town Forest.
Snapping and Painted, as well as the more rare Spotted and Box turtles, often seen in the wooded and shore areas.
A variety of birds such as Ring-necked and Black ducks, Buffleheads, Hooded Mergansers, herons, Kingfishers, and egrets congregate around the pond.
Approximately 100 pairs of Tree Swallows that inhabit the nesting boxes placed throughout the marsh.
Mink along the water’s edge and muskrat and otters in the pond.
