MLK Day of Service: FOPOS Land Stewardship Volunteer Sessions // 1.19.2026
Details
Description
Join the Friends of Princeton Open Space (FOPOS) on MLK Day for a volunteer land stewardship session on Monday, January 19th, 2026, and honor Dr. King's dedication to service and community.
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.
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!
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.
Event waiver: Please complete this event waiver - fopos.org/waiver. This needs to be completed once per calendar year.
