# Event Details - **Event Name**: LOVE Your Park Day: FOPOS Land Stewardship Volunteer Sessions // 2.28.2026 - **Event Start and End Date**: Sat, 28 Feb, 2026 at 10:00 am – Sat, 28 Feb, 2026 at 03:00 pm - **Event Description**: Join FOPOS for a volunteer session at the Billy Johnson Mountain Lakes Nature Preserve.About this EventShow your LOVE for the Billy Johnson Mountain Lakes Nature Preserve! Join the Friends of Princeton Open Space (FOPOS) for a volunteer stewardship session on Saturday, Feb. 28th, 2026. Volunteers will work under the guidance of the FOPOS stewardship staff to perform ecosystem restoration and invasive species removal in the Billy Johnson Mountain Lakes Nature Preserve. If you have tools and can bring them along, please do!We have two volunteer sessions: 10AM-12PM and 1PM-3PM. Please pick the timeslot that works best for you! You are also welcome to attend both sessions. Groups welcome!About the volunteer work: Volunteers will perform important riparian restoration work. This may include removing invasive species and freeing trees from vines. The dense cover formed by invasive plants prevents young tree saplings from growing into future canopy trees and degrades habitat quality for wildlife. We will be using pruners, loppers, and hand saws to cut back invasive shrubs and vines. Volunteers will learn how to identify target invasive species and tool safety. The stewardship skills learned at these sessions can easily be applied to restoring habitat in your own backyard. FOPOS's wonderful stewardship staff will be on hand to share this knowledge and much more!What to wear & What to bring: We recommend wearing long sleeves, long pants, and work boots; this will best protect you from thorns, muddy areas, ticks, and poison ivy. If you have work gloves and tools like loppers and pruners, bring them along! We will have extra tools and gloves on site.Why is this work important: Our current focus is on a 25-acre riparian restoration project that buffers Mountain Lake and portions of its feeder streams. Riparian areas play an important role in protecting water quality by slowing down stormwater and filtering out pollutants before they enter the water system. Water that flows through Mountain Lake ultimately finds its way into the Raritan River, an important drinking water source for central New Jersey. Riparian areas also provide critical habitat for birds, insects, and aquatic life.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. Here is a link to the parking lot location on Google Maps & Apple Maps. The address of the Preserve is 57 Mountain Avenue, Princeton, NJ 08540; this will bring you to the entrance of the Preserve, not our meet-up location. To get to the Mountain Lakes House parking lot, look for the white gate along Mountain Avenue, marked by a series of black mailboxes along the road. Drive slowly down the long paved driveway. The gravel parking lot will be on your left, approximately 1/2 mile down the driveway.Event waiver: Please complete this event waiver - fopos.org/waiver.

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." } ] } ] ```
