Answer:

Prairies are one of the most recently developed ecosystems in North America, formed after the period of Pleistocene glaciation. About 18,000 years ago, much of Illinois was covered by glaciers. As the glaciers melted, the land was covered at first with tundra type vegetation, then by spruce forests.
