Abstract

We investigated the fire-induced variability in the 1999-2005 time series of Normalized Difference Vegetation Index (NDVI) from SPOT-VEGETATION sensor for two different types of vegetation sites: fire un-affected and fire-affected. The statistical analysis, performed by using the detrended variation analysis (DFA), it appears 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 variation analysis, spot-vegetation sensor.
