|A summer view of the South River from the Francis Keville Bridge in Marshfield.|
In September 1977, the Foleys and Finn provided a boat tour of the North and South Rivers to Dr. H. W. Vogelmann Ph.D., who had been contracted by the government to review the rivers for NNL designation. Vogelmann also viewed the area from an airplane, and at the end of the year submitted an evaluation to the Department of the Interior, recommending that the rivers receive the designation.
Vogelmann observed that, “the marshland systems of the North and South Rivers are extensive and complex,” and noted that the rivers were “classic examples of drowned river mouth estuaries.” He said, “Extensive marshland systems and relatively unpolluted rivers are a rare occurrence near a metropolitan area like Boston.”
National Natural Landmark status was conferred soon thereafter. This was especially significant because until then, the program had only accepted more nationally well-known sites. There were only 66 NNLs at that time.
“But nothing happened,” remembers Finn.
The official designation date for the North and South Rivers as a National Natural Landmark is 1977. But according to Finn, it took several years for the designation to be declared. Repeated inquiries to the National Park Service (NPS), attempting to determine whether or not the rivers would receive the designation, yielded nothing. Finally in 1979, after Tsongas was elected to the US Senate, the wheels began to turn. Theta Leonard, who worked for Tsongas, along with the senator and Bill Finn, collaborated with the NPS to tie up loose ends.
Finally in May 1980, during the second annual Massachusetts Rivers Celebration, a dedication ceremony was held at Mass Audubon’s North River Sanctuary in Marshfield. Tsongas, several local political figures, as well as representatives from the NPS and other state and federal agencies, joined NSRWA members and officials for a canoe trip down the North River. Two wooden signs were presented, but they were not the type that could be installed outdoors. With the installation of the plaque on September 23rd, the final loose end will – finally! — be secured.
According to the NPS “the National Natural Landmarks program recognizes and encourages the conservation of outstanding examples of our country’s natural history.” To date, 599 sites have been designated. In order to obtain NNL status, the site must be “one of the best examples of a natural region’s characteristic biotic or geologic features.”
All sorts of different landscapes may be considered for NNL designation. The present sites include lands used for ranching, agriculture, recreation, nature preserves, research areas, camps, conference centers, and commercial ventures. They vary in size from a 7-acre bog to a 960,000-acre glacier. Some, like Connecticut’s Dinosaur Trackway, involve only a single remarkable feature, while others encompass large, widely diverse landscapes. Public access is not a foregone conclusion. Some NNLs may be too ecologically fragile to permit visitors – or it might be the best remaining example – in the country, or even worldwide — of a certain, often irreplaceable, type of landscape feature. Unlike the lands in the National Park system, National Natural Landmarks are not owned or managed by the federal government. They may be privately or publicly owned.
The Natural Landmark program’s aim has been ”to encourage and support voluntary preservation of sites that illustrate the geological and ecological history of the United States, and to strengthen the public’s appreciation of America’s natural heritage.” In order to maintain NNL status, the only requirement is that the “significant natural values of the site” are preserved as much as possible. No new land use restrictions are set upon the site. The NPS does make occasional visits to verify a site’s condition and maintain good rapport with landowners.
