In 2001, Bergman Slough Preserve was a fallow, row-crop farm field, interspersed with degraded sections of remnant prairie savanna that since has been restored to high quality native prairie, wetland, and savanna of award-winning regional importance. Join staff from the Forest Preserves of Cook County, Openlands, and the Bird Conservation Network on a walk to learn of the history of Bergman Slough and the adjacent woodland in Cap Sauers Holdings; of the exemplary use of natural prairie landscaping, ecological restoration, and conservation design; and to observe present day native plants such as White Wild Indigo, Wild Hyacinth, Blue-eyed Grass, and Golden Alexanders and bird species of conservation concern breeding there now such as Henslow's Sparrows, Grasshopper Sparrows, Red-headed Woodpeckers, and Osprey.
