Restoration Over 5 Years

Tidmarsh Wildlife Sanctuary was once a working cranberry bog but has since been restored to a functioning wetland wildlife sanctuary. The restoration of the area was a major undertaking that involved the removal of cranberry bog dikes and the rerouting of a nearby river. 

These changes have allowed the wetlands to naturally flood and drain, which has helped to create a thriving habitat for many species of wildlife. In addition to restoring the wetlands, the sanctuary also features walking trails and boardwalks that allow visitors to explore the area while minimizing their impact on the ecosystem.
