             abstract = "In Cerrado (Brazilian savanna) the vegetation state and evolution 
                         are strongly conditioned by climatic seasonality and forest fires. 
                         Fires in the Cerrado are events that strongly influence the 
                         dynamics of Cerrado. They trigger a series of complex bio-physical 
                         and ecological processes and their actual impacts on vegetation 
                         are widely discussed among scientists. The present study aims at 
                         characterizing the recovery period of Cerrado vegetation after 
                         fire events in protected areas of the Federal District - Brazil 
                         using MODIS vegetation indices. We selected various zones of study 
                         within protected areas with and without recorded fires. Vegetation 
                         index NDVI and EVI of MOD13Q1 from MODIS/TERRA are used to 
                         construct data time series. The images are from the period 
                         2000-2012, with a 250 m spatial resolution and a 16-day sampling 
                         period. The spectra of NDVI and EVI were obtained after making a 
                         3D multitemporal data cube. Using criteria solely based on remote 
                         sensing data, we find that in natural sites (campos naturais) and 
                         Cerrado in the narrow sense the time-lag necessary for the 
                         vegetation to recover after a fire event is, respectively, in 
                         average 94 and 100 days when considering NDVI data, and 102 and 
                         105 days, respectively, for natural sites (campos naturais) and 
                         Cerrado in the narrow sense when considering EVI data. This result 
                         does not imply that the floristic composition is identical to what 
                         it was before the fire, but it shows a very rapid recoverability 
                         of the Cerrado vegetation which is somehow has adapted itself to 
                         the high frequency of these events.",
