Meet at the Furnace Stack and help remove the invasives along the water race and the furnace at Pine Grove Furnace State Park. Bring Gloves, a mask and water. Assist in removing barberry, privet, autumn olive, and mugwort from these areas. Any amount of time you can give will help us remove invasive species and provide areas for natives to regenerate. Pre-registration required HERE. Masks are required to be worn at all events.
