The Massachusetts Audubon Society, founded in 1896 by Harriet Hemenway and headquartered in Lincoln, Massachusetts, is a nonprofit organization dedicated to "Protecting the nature of Massachusetts." Mass Audubon is independent of the National Audubon Society, and in fact was founded earlier.
Together with more than 100,000 members, Mass Audubon cares for 34,000 acres (140 km2) of conservation land, provides educational programs for 225,000 children and adults annually, and advocates for sound environmental policies at local, state, and federal levels. Mass Audubon's mission and actions have expanded since its beginning in 1896 when its founders set out to stop the slaughter of birds for use on women's fashions. Today Mass Audubon is the largest conservation organization in New England. Mass Audubon's statewide network of wildlife sanctuaries, in 90 Massachusetts communities, welcomes visitors of all ages and serves as the base for its work.
