The land comprising Woodbury has undergone many conversions. From early agriculture and timbering to recent strip-mining, the area contains a diverse mixture of habitat types from expanses of grasses and legumes to relatively undisturbed woodlands. Approximately 35 percent of the area is in openland, 8 percent in brushland, and 57 percent in woodland. There are over 150 small water impoundments on the area, most of which were developed during strip-mining activities. This number includes 42 wetlands and 116 ponds.
