About Tidmarsh

Once a working cranberry farm, this landscape underwent the largest freshwater ecological restoration ever completed in the Northeast. Now Tidmarsh Wildlife Sanctuary is 481-acre property that's home to a vast expanse of cold-water streams, ponds, forest, and woodlands—all permanently protected and open for everyone to enjoy!

Its previous owners, the Schulman Family—along with the Massachusetts Division of Ecological Restoration, U.S. Department of Agriculture's Natural Resources Conservation Service, and many other organizations—re-created nearly three and a half miles of meandering stream channel, sculpted the land's surface, and removed nine dams to reconnect the headwaters of Beaver Dam Brook to the ocean for the first time in more than a century.

As a result of the collective actions of the collaborators, this entire landscape is now on a dramatic trajectory of change—a spectacle that will play out for decades, and even centuries, to come. Walk the trails to learn about the landscape's transformation and the importance of habitat protection, ecological restoration, and climate change response.
