Wilderness Park consists primarily of woodlands in various successional stages along a major creek.
In addition to woodland, there are scattered marshes, oxbow lakes, and oldfield grasslands. Wilderness Park is linear with a great deal of edge habitat. Fragmentation, due to road crossings, railroads, powerline and gas line corridors, and extensive trail systems also increase edge habitat. Disturbances assist in maintaining the ecological integrity of these systems. Oak and prairie ecosystems were an important component of the pre-settlement landscape in this region.
