In celebration of Earth Day, Wickliffe Mounds will have a tree planting event beginning at 9:30 a.m. Volunteers for planting trees will meet in the Welcome Center to get an overview of the project plans. Trees native to this region will be planted in areas of the park grounds that are not part of the archaeological deposits in order to maintain the protection of the site. An interpretive program about the Natural Environment of the Mississippian culture and the Woods Walk trail will be conducted after the tree planting. Volunteers are encouraged to bring work gloves, orange safety vest, and a sack lunch.
