Join us for a workday at the 294-acre Olin Nature Preserve. Volunteers will be helping to remove invasive plants and shrubs from the woodland. Please be sure to wear protective clothing and sturdy shoes. Volunteers are also encouraged to bring gloves, water, clippers or loppers if you have them. Some tools will be available on site. Please call the TNI office at (618) 466-9930 with any questions. Hope to see you there!
