             abstract = "Covering almost a quarter of Brazil, the Cerrado is the world's 
                         most biologically rich tropical savanna. Fire is an integral part 
                         of the Cerrado but current land use and agricultural practices 
                         have been changing fire regimes, with undesirable consequences for 
                         the preservation of biodiversity. In this study, fire frequency 
                         and fire return intervals were modelled over a 12-year time series 
                         (1997-2008) for the Jalap{\~a}o State Park, a protected area in 
                         the north of the Cerrado, based on burned area maps derived from 
                         Landsat imagery. Burned areas were classified using object based 
                         image analysis. Fire data were modelled with the discrete 
                         lognormal model and the estimated parameters were used to 
                         calculate fire interval, fire survival and hazard of burning 
                         distributions, for seven major land cover types. Over the study 
                         period, an area equivalent to four times the size of Jalap{\~a}o 
                         State Park burned and the mean annual area burned was 34%. Median 
                         fire intervals were generally short, ranging from three to six 
                         years. Shrub savannas had the shortest fire intervals, and dense 
                         woodlands the longest. Because fires in the Cerrado are strongly 
                         responsive to fuel age in the first three to four years following 
                         a fire, early dry season patch mosaic burning may be used to 
                         reduce the extent of area burned and the severity of fire effects.
