Ancient Oaks a Living Link to Big Grove

When people think about the landscape of central Illinois prior to European settlement they tend to think “prairie,” vast expanses of flat land covered in tall grass and tall flowers. And for the most part, that image is accurate. But groves of trees intruded on the grasslands here and there, especially on the eastern edges of rivers and streams, creating natural breaks to prairie fires driven by winds from the west.

For me, that means it’s a great time to renew appreciation for the undramatic nature that surrounds us every day.
