As we wander, we’ll keep an eye out for birds and other wildlife, all quietly marking the season’s change. Our stewardship team will also share insights into the history of the Preserve and the ongoing land stewardship efforts that help protect this special place for future generations.Be sure to wear sturdy, weather-appropriate footwear. Feel free to bring a camera or binoculars along to help you spot and capture the beauty of wildlife as we explore.Meetup Location: Mountain Lakes House Parking LotDirections & Parking: We will meet at the Mountain Lake House parking lot, located within the Billy Johnson Mountain Lakes Nature Preserve.

Throughout the Princeton region, FOPOS works with groups to support efforts to preserve and protect open space and the environment. In 2019, FOPOS will celebrate it's 50th year.Since its founding, FOPOS has helped to establish over 1,000 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 to raise over $5 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." } ] } ] ```
