TreeKeepers work throughout the region to keep trees healthy, administering proper care and promptly recognizing and reporting harmful pests. Since 1991, nearly 2,000 trained volunteers have provided eyes and ears on the ground year round in neighborhoods all over Chicagoland to identify potential tree-related problems and lead neighbors in tree planting and tree care.

TreeKeepers learn how to help keep trees green and growing, volunteering in a variety of situations from street tree care and tree planting to woodland stewardship and advocacy. They are passionate ambassadors who help educate their neighbors as well as their public officials about the importance of trees for the greater good.

For 28 years, TreeKeepers have supported the work of local forestry officials, such as the Chicago Bureau of Forestry, the Chicago Park District, the Chicago Region Trees Initiative (CRTI), and the Forest Preserves of Cook County.
