WThe Massachusetts Audubon Society, founded in 1896 by Harriet Hemenway and Minna B. Hall, headquartered in Lincoln, Massachusetts, is a nonprofit organization dedicated to "protecting the nature of Massachusetts". Mass Audubon is independent of the National Audubon Society (NAS), just as in the neighboring state of Connecticut, where Connecticut Audubon Society is independent of the NAS. Both Mass Audubon and Connecticut Audubon Society were founded earlier than the NAS. Mass Audubon protects 36,500 acres of land throughout Massachusetts, saving birds and other wildlife, and making nature accessible to all with its wildlife sanctuaries and 20 nature centers.
