Threats To The Prairie
Timber is a natural enemy of the sun loving prairie. The invading woody plants move slowly up hillsides, increasing in growth until their shade eliminates the prairie vegetation. The first plants to begin the assault are coralberry, sumac and dogwood.

The scant trees that existed hugged the water ways. Around the 1850's, change came to the Loess Hills. Farms, communities and roads checked the wilderness that had cleansed the prairie of the always encroaching trees and woodland plants and, as you can see now, trees blanket most of the hills.
