Winner of the Illinois State Historical Society Outstanding Achievement Award Efforts to preserve wild places in the United States began with the allure of scenic grandeur: Yosemite, Yellowstone, the Grand Canyon.

Fell transformed a loose band of ecologists into The Nature Conservancy, drove the passage of the influential Illinois Nature Preserves Act, and helped spark allied local and national conservation organizations in the United States and beyond.
