Abstract
  • Could the dynamics of vegetation covers be significantly influenced by fires? Is it possible to identify and quantify such effect? In order to detect fire-induced variability in vegetational dynamics, we performed a fluctuation analysis of time series of satellite SPOT-VEGETATION normalized difference of vegetation index (NDVI) data from 1998 to 2003 of two shrub-land test sites. We used the detrended fluctuation analysis (DFA), which permits the detection of persistent properties in nonstationary signal fluctuations. We analyzed two shrub-land sites, one in \"healthy conditions\" (fire-unaffected) and the other in \"ill conditions\" (fire-affected). Our results point out to the active role played by fires in increasing the persistence of the vegetation dynamics. (literal)
