We improve the health of our communities by preserving and restoring natural areas and open space, protecting rivers and watersheds, and promoting stewardship of our environment. The support of more than 5,000 members and 500 volunteers helps us carry out our mission. We focus our work in DuPage, Kane, Kendall and Will Counties where we have helped preserve more than 35,000 acres of open space, and we also go where we are needed in LaSalle, DeKalb and Grundy Counties.
