What Is The Last Green Valley?

The Last Green Valley at Night

The Last Green Valley is two things – it’s the 35-town National Heritage Corridor in eastern Connecticut and south-central Massachusetts, and it’s also your member-supported, non-profit stewardship organization working for you in the National Heritage Corridor.  We help you to care for it, enjoy it, and pass it on to the next generation.

At night, the region appears distinctively dark amid the urban and suburban glow when viewed from satellites or aircraft.  In the daytime, the green fields and forests confirm the surprisingly rural character of the 1,100 square-mile area defined by the Quinebaug and Shetucket Rivers systems and the rugged hills that surround them.  For this reason, northeastern Connecticut and south-central Massachusetts have been called “The Last Green Valley” in the sprawling metropolitan Boston-to-Washington Corridor.

The Last Green Valley is half the size of Grand Canyon National Park and more than ten times that of Acadia, the largest national park in the northeast.  Forest and farmland make up 77% of its 707,000 acres, yet it lies only an hour from 3 of New England’s 4 largest urban areas.  Its 300,000 inhabitants reside only 2 1/2 hours from 25 million people.  This relatively undeveloped rural island in the midst of the most urbanized region in the nation makes it a resource of local, regional, and national importance.

Congress designated this region as The Last Green Valley National Heritage Corridor, recognizing the region as a unique national resource. Congress included 35 towns, 26 in Connecticut and 9 in Massachusetts.  The Massachusetts communities are:  Brimfield, Charlton, Dudley, E. Brookfield, Holland, Oxford, Southbridge, Sturbridge, and Webster.  The Connecticut municipalities are:  Ashford, Brooklyn, Canterbury, Chaplin, Coventry, Eastford, Franklin, Griswold, Hampton, Killingly, Lebanon, Lisbon, Mansfield, Norwich, Plainfield, Pomfret, Preston, Putnam, Scotland, Sprague, Sterling, Thompson, Union, Voluntown, Windham, and Woodstock.
