Support Friends of Princeton Open Space

Founded in 1969, FOPOS is a nonprofit organization dedicated to acquiring open space in Princeton for preservation, protecting natural resources, maintaining accessibility to trails, and providing environmental education. As part of our mission, we work with groups in the Princeton region to support efforts to preserve and protect open space and the environment. Since our founding, we’ve helped raise over $4.5 million to purchase land and conservation easements in Princeton.

There are several ways you can support our mission: become a member, donate to our annual fund, and join our team of land stewards. Know that your monetary donation and/or donation of your time as a volunteer are equally appreciated.

DONATE

If you’re already a FOPOS member or wish to donate above the membership levels, please consider contributing to our annual fund. Your support helps us fulfill our mission of acquiring open space for preservation, protecting natural resources, maintaining accessibility to trails, and providing environmental education.

BECOME A LAND STEWARD

We rely on the help of volunteers to complete our ambitious goals.  Throughout the year, FOPOS hosts stewardship sessions, days of service and group sessions through local organizations and businesses.

No experience necessary, just a love of nature and the outdoors.
