Table 4 Outcomes of forecast analyses comparing observations at fire-treatment and fire-free control units of Gibbons Creek Barrens Natural Area, Pope County, Illinois, USA, from 2006, 2013, and 2017, to trends predicted within 95% confidence intervals (CI) from a 7-year early-estimation period (1989 to 1995). Also shown are outcomes from a separate analysis using a wider estimation period (1989 to 2006). x = based on forecast period from 1989 to 1995; y = based on forecast period from 1989 to 2006. GCB = Gibbons Creek Barrens, FSB = Forest Service Barrens
