About Mass Audubon

Who We Are

Mass Audubon is the largest nature-based conservation organization in New England. Founded in 1896 by two women who fought for the protection of birds, Mass Audubon carries on their legacy by focusing on the greatest challenges facing the environment today: the loss of biodiversity, inequitable access to nature, and climate change.

With the help of our 160,000 members and supporters, we protect wildlife, conserve and restore resilient land, advocate for impactful environmental policies, offer nationally recognized education programs for adults and children, and provide endless opportunities to experience the outdoors at our wildlife sanctuaries. 

Diversity, Equity, & Inclusion

Advancing the principles of diversity, equity, inclusion, justice, and accessibility (DEIJA) is both a moral imperative and a necessity for the success of our mission. Mass Audubon is committed to promoting inclusive and equitable access to nature by protecting and restoring greenspaces in urban environments, expanding and deepening our environmental and career programs, and advancing the values of DEIJA throughout our organization in our training, recruitment, and board development activities.
