Shawnee National Forest Final Environmental Impact Statement Land and Resource Management Plan Alexander, Gallatin, Hardin, Jackson, Johnson, Massac, Pope, Saline, Union and Williamson Counties, Illinois Lead Agency USDA Forest Service Responsible Official Randy Moore, Eastern Regional Forester 626 East Wisconsin Avenue Milwaukee, WI 53202 For Information, Contact Stephen Hupe 50 Highway 145 South Harrisburg, IL 62946 (618) 253-7114 or (800) MY WOODS Abstract This final environmental impact statement (FEIS) documents the analysis of four alternatives, each offering a different programmatic framework within which to manage the 285,000 acres administered by the Shawnee National Forest. The selected alternative was the basis for the revised Forest Plan that will guide all natural resource management on the Forest. The Forest Service developed the alternatives with advice from the public and other federal and state agencies. The Regional Forester explains in the Record of Decision his rationale for selecting one of the alternatives. Alternative 1 would continue to use the management direction of the 1992 Amended Forest Plan, with uneven-aged forest management and group-selection harvest, minimally restricted equestrian use and proposed ATV/OHM trail corridors. Alternative 2, the selected alternative, emphasizes maintenance or enhancement of biodiversity on the Forest, with even-aged forest management to restore and maintain oak-hickory forest-type, prescribed fire and other vegetation management, restriction to trails of equestrian use and continuation of the closure of the Forest to ATV/OHM use. Alternative 3 emphasizes custodial management of the Forest, with no forest management, minimal prescribed fire, restricted equestrian use and no ATV/OHM use. Emphasis of Alternative 4 is similar to Alternative 1, with more equestrian and ATV/OHM use possible, and to Alternative 2, with even-aged forest management to restore and maintain oak-hickory forest-type, prescribed fire and other vegetation management.
