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.
