Description
The highest quality features at Bergman Slough Nature Preserve are the remanent savanna and freshwater marsh. Remnant dry-mesic savanna sustains a large population of a state-threatened species and more than a dozen bird Species in Greatest Need of Conservation according to the Illinois Wildlife Action Plan. Freshwater marsh supports foraging habitat for a state-endangered bird and stopover habitat for migratory waterfowl. In addition, reconstructed dry-mesic and mesic prairie natural communities are home to several grasslands bird species that are sensitive to habitat fragmentation, such as Henslow’s sparrow, grasshopper sparrow, Savannah sparrow, dickcissel, field sparrow, eastern meadowlark, and bobolink.
