c/o The-Morton Arboretum -- Our goal:
To make a significant, measurable improvement to the regional forest and the lives of its inhabitants by the year 2050.
Chicago’s regional forest is a critical asset that needs our protection. Trees clean our air and water, reduce flooding, improve our property values, create habitat for wildlife, and provide significant social and health benefits. In short, trees improve our quality of life. But our trees need our help. They face threats such as invasive plants, including buckthorn and honeysuckle; the death of ash trees due to emerald ash borer; and a lack of funding for proper tree care. These issues are having significant impacts on the health and survival of our regional forest.




The Chicago Region Trees Initiative (CRTI) is a partnership for coordinated action on key issues facing trees. It is the largest such initiative in the country, with leading organizations and agencies from across the seven-county metropolitan region working together. CRTI is leveraging funding, knowledge, skills, and expertise to build a healthier, more diverse regional forest.
