We investigated the fire-induced variability in the 1998-2003 time series of Normalized Difference Vegetation Index (NDVI) from SPOT-VEGETATION sensor for two different kinds of vegetation sites: fire un-affected and fire-affected. The statistical analysis, performed by using the detrended fluctuation analysis (DFA), showed that fires contribute in increasing the persistence of time dynamics of vegetation, driving unstable patterns in vegetation dynamics of burned areas.

Key words: Fires, NDVI, detrended fluctuation analysis.
