An ambitious plan to protect the Sandy Brook watershed, a 17-mile expanse of land that crosses northeastern Norfolk as well as parts of Colebrook, Sandisfield, and other surrounding towns, is being spearheaded by Aton Forest. A broad coalition of land-preservation groups, municipalities, and landowners will be called on to bring this effort, known as the Sandy Brook Conservation Corridor Project, to fruition. Special attention will go to preserving the headwaters and wetlands that feed Sandy Brook, and to protecting contiguous parcels of land that can sustain biological diversity. A lecture, the first of a series, will be offered at the Colebrook Community Center on May 19. Further information is available on Aton Forest’s website.
