Once a working cranberry farm, this landscape underwent the largest freshwater ecological restoration ever completed in the Northeast. Now Tidmarsh is a 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!

The NestWatch program is a volunteer-based project focused on collecting breeding bird data for nest-box nesting bird species. Through this volunteer program, over 170 nest boxes were monitored this year at 6 of the South East sanctuaries.
