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.",
