Chicago has more than 500,000 parkway trees and each is maintained by the DSS (Department of Streets and Sanitation) Bureau of Forestry. In addition to planting parkway trees, the DSS Bureau of Forestry trims thousands of trees a year, addresses insect and disease problems, and otherwise promotes tree health throughout Chicago. DSS Bureau of Forestry crews also respond to tree emergencies in the public way at all hours.
The DSS Bureau of Forestry works in cooperation with the US Forest Service and the Great Lakes Restoration Initiative.
