Vegetation

The area’s ecosystem has undergone substantial transformation in the last 150 years. Historically, the area was a blend of oak savanna/prairie and oak-hickory forest with some maple, black cherry, basswood and white ash. Today, the native prairie has been removed, although there have been some attempts to re-establish it.

The oak savanna has either been removed for farming and pasture or has overgrown and reverted to forest. Some of the wide spreading open grown oaks can still be found.

The oak-hickory forest has been invaded by buckthorn, honeysuckle, Norway maple and garlic mustard. The periodic fires that maintained the prairie also burned these forests and had prevented the large shrub layer now found under trees.

Todays forest mixes naturally occurring species, planted trees and escaped exotics. The Norway spruce and pine plantations have melted into the landscape. Buckthorn is found everywhere that isn’t mowed, paved or water-covered — except where landowners have taken on the job of removing brush.
