Olson Park was once a gravel pit, but is now a place to play soccer, ride a mountain bike, or take a hike. It’s also home to many butterflies including the declining Monarch. Invasive weeds are invading the open meadows, threatening pollinator habitats. Join us to pull these non-native plants. Meet at the entrance on Dhu Varren Road, just east of Pontiac Trail (map: tinyurl.com/OlsonParkingLot) Pre-registration through VolunteerHub is encouraged; please stay home if you are feeling ill. NAP continues to monitor recommendations from health officials, volunteers registered for events will be notified in advance of any changes to the workday. Please wear long pants and closed-toed shoes, and wear socks that close the gap between shoes and pants. Bring a water bottle and gardening gloves if you have them. All minors should be accompanied by a guardian. Tools and know-how provided. Register at tinyurl.com/Olson071022
