Green Acres acquired the Ramsaysburg property in 2000 to become a part of the Beaver Brook Wildlife Management area. But the Department of Environmental Protection was unable to maintain or protect any of the structures of the hamlet. The Knowlton Township Historic Commission worked with the Township of Knowlton to arrange a lease of the property from the DEP.

Saving Ramsaysburg required state, county and local funding to stabilize the buildings, as well as extensive research to support listing the site on the New Jersey and the National Register of Historic Places. Since 2002, the Knowlton Township Historic Commission has applied for and received grants from the Warren County Cultural & Heritage Commission, Warren County Municipal and Charitable Conservancy Trust Fund, Delaware River Greenway Partnership, Garden State Historic Preservation Trust Fund/New Jersey Historic Trust, and the National Park Service/Martins Jacoby Watershed Association.
