FOPOS Fall Bird Walk with Winnie Hughes Spar // 10.11.25

Friends of Princeton Open Space(FOPOS), founded in 1969, is a non-profit, tax-exempt organization devoted to acquiring open space in Princeton for preservation, protecting natural resources, maintaining accessibility to trails, and providing environmental education. Throughout the Princeton region, FOPOS works with groups to support efforts to preserve and protect open space and the environment.Since its founding, FOPOS has helped to establish over 1,800 acres of parkland and a network of trails that nearly encircles Princeton.  Through grants and the contributions of hundreds of people in the community, FOPOS has helped raise nearly $10 million for the purchase of land and acquisition of easements on properties that might have been bulldozed for development.  In addition to land preservation, FOPOS also leads in stewardship, from creating and maintaining hiking trails, boardwalks and footbridges, to the removal of invasive species and the replanting of native varieties.FOPOS also sponsors community programs and activities, such as nature walks and educational workshops, and advocates for governmental actions that protect our water, land, animals and plant communities. If you have an interest in spending time outdoors, enjoying nature and making a difference in the community, please contact us at info@fopos.org to get involved in trail-building and ecological restoration.
