Abstract: The Peabody Wildlife Management Area (PWMA) consists of coal surface mined lands and coal waste disposal sites varying in age from pre-law to current regulations. Established in 1995, the PWMA occupies 73,000 acres in Ohio, Muhlenberg, and Hopkins counties in Kentucky. Located in the physiographic area known as the Shawnee Hills, the PWMA is comprised of eight management units. The Homestead and Ken-Hopewell Units in Ohio County have been the focus of management efforts to change grasslands dominated by sericea lespedeza, Ky 31 fescue, and thistle to native warm-season grasses (NWSG). In 1997, a native grassland landscape restoration goal of 5,000 acres was established. Since that time, 2,754 acres of NWSG have been established. Management techniques have included installation of 20 miles of fire lanes, rotational fall and winter prescribed burning, repetitive multi-brand herbicide spraying in spring and fall for two to three successive years, and varied planting rates and methods. Seeding rates have ranged from 6 to 12 lb/ac of pure live seed (PLS) using Truax Flex II no-till drills. Establishment of native forbs has met with marginal success due to reinfestation of NWSG fields by sericea lespedeza when fields are manipulated by ground disturbance such as discing. Broadleaf herbicides such as Garlon and Plateau have not been selective for residual suppression of germinating sericea in the soil bank. Field test plots using Vista and Escort XP herbicides are now being monitored for residual sericea suppression. Garlon and 2-4D mixtures have been very successful in thistle control. Quail Unlimited and U.S. Fish and Wildlife have been major partners in the departmentís efforts to establish NWSG on a landscape scale while controlling exotic flora.
