The Chicago Trees Initiative (CTI) is an exciting new opportunity for the City of Chicago to help improve quality of life by increasing public awareness about the value and importance of trees. By preserving and planting trees, we increase our urban forest - one of the most valuable environmental assets on the planet. In order to be successful, we need the support and enthusiasm of everyone, in both public and private sectors. This Web site contains the information and resources that are keys to our success. Take a few minutes to learn about the impact that trees have on our City, and how you can help. It's easier than you think.
