prairie plants at West Branch


Before settlement, the preserve was made up of prairie, wet/marshy prairie and scattering timber surrounding the West Branch DuPage River. The preserve was primarily under cultivation. Miles of drain tiles were installed and drained into the river. Several home sites dotted the landscape, including the Baker Homestead, still standing along St. Charles Road near Prince Crossing Road.

The bulk of the preserve was purchased in the mid-1970s, with parcels added in the intervening decades.
