Massachusetts Audubon Society

Established in 1896, the Massachusetts Audubon Society (Mass Audubon) is the largest conservation organization in New England, working to protect the nature of Massachusetts for people and wildlife. Mass Audubon protects more than 40,000 acres of conservation land, provides educational programs for 200,000 children and adults annually, and advocates for sound environmental policies at the local, state, and federal levels. Our statewide network of 60 wildlife sanctuaries welcomes 500,000 visitors of all ages each year and serves as the base for our conservation, education, and advocacy work as well as providing people with much-needed places for recreation and relaxation, and a home for more than 150 endangered and threatened native species.
