Why You Should Visit
The Black Pond Nature Preserve encompasses several habitat types: Atlantic white cedar swamp, forest, a small meadow and — most significant ecologically — a bog surrounding Black Pond.

The pond itself is a deep glacial kettlehole which has a limited water supply. Its water is naturally extremely acidic and low in nutrients. These factors, in combination with a cool, coastal climate, make the bog plant community unusual.

Why the Conservancy Selected This Site
The quaking sphagnum bog creates habitat for a unique plant community at Black Pond, which was the first Nature Conservancy preserve in Massachusetts.

What the Conservancy Has Done/Is Doing
This preserve was managed in cooperation with the Massachusetts Audubon Society for many years and Audubon continues to lead walks on the property. The boardwalk was closed for seven years in the 1970’s due to overuse, however, the bog has recovered. In 2004, Nature Conservancy staff added new signs and repaired the boardwalk.

Open year-round

What to See: Plants
As plants grow inward from the edges of Black Pond, they cover the water with a floating, sponge-like mat of sphagnum moss which harbors sundew, sedges, cranberry, cottongrass, swamp loosetrife and Virginia chain fern.

Surrounding the bog mat is a wet shrubby zone containing wild blueberry plants and Atlantic white cedar. The shrub zone grades into a red maple swamp as one moves away from the pond, and at the perimeter of the swamp is an upland forest dominated by oak, beech and hemlock, with scattered American holly.

All reasonable requests for special accommodations will be made with ample notice.

Check out a great video by Jeff Gold about Black Pond Bog and Wes Osborne, the preserve's longtime champion and caretaker.

Suitable for all ages, this short trail and connecting boardwalk will take you through upland forest and cedar swamp to close-up views of the bog’s rich and unique vegetation. For a longer hike, this path connects with a trail system on abutting town land.
