In 1972 the Block Island Conservancy was founded. Capt. Rob Lewis spearheaded this campaign to “Save Open Space”. He was also a member of the Historical Society Board of Directors for many years and was instrumental in having the vision to help the Society move the Southeast Lighthouse.  The Conservancy and other land conservation organizations are responsible for protecting over 43% of the island from development. Greenway trails have been established across the island. The Society conducts off site tours which include some Conservancy land with historic sites, specifically the Native American Village site on Great Salt Pond. Tours of the smaller island cemeteries also include walks on the Island’s greenway trails. Sheffield Cemetery off Corn Neck Road , Winfield Dodge Preserve: historic foundation and views of the southwest side of the island;Palatine Graves and  Lewis Dickens trail includes info about the “Bird Lady” Elizabeth Dickens and her dedication to preserving Block Island’s land and culture.
