Brookfield’s Open Spaces are being overrun with invasive plant species and the Conservation Commission is looking for volunteers to help remove them.  If these plants aren’t controlled, officials say forests and meadows will be permanently damaged, along with wildlife and native plants.  Volunteers are needed Sunday from 9am to noon, meeting at Williams Park Entrance.  Volunteers are asked to bring garden gloves and gardening tools, including pruning shears. A Master Gardener will be available to help identify and provide information about the dangers of invasive species.
