The Walden Woods Project (WWP) is a nonprofit organisation located in Lincoln, Massachusetts, devoted to the legacy of Henry David Thoreau and the preservation of Walden Woods. It was founded in 1990 by recording artist Don Henley to prevent two development projects in Walden Woods, the forest around Walden Pond that spans Lincoln and Concord, Massachusetts. Its mission has since expanded from conservation to research and education on the works of Henry David Thoreau. In 1998 the Thoreau Institute at Walden Woods was founded as part of the Project; today its library houses a collection of Thoreau-related resources. - Source: Wikipedia
