Join FOPOS for a special Earth Day Community Volunteer Event at the Billy Johnson Mountain Lakes Nature Preserve in Princeton, NJ. Volunteers will work under the guidance of FOPOS’ stewardship staff to perform riparian and forest restoration in the Billy Johnson Mountain Lakes Nature Preserve. Join us as we head out to one of our restoration project sites for critical tasks such as invasive species removal, spring planting, or installing cages around native plants to protect them from deer & beaver browse. We have two volunteer sessions: 10am-12pm and 1pm-3pm. Please pick the timeslot that works best for you!
