Short-term temporal and spatial analysis for post-fire vegetation regrowth characterization and mapping in a Mediterranean ecosystem using optical and SAR image time-series

In the present study, temporal and spatial dynamics of post-fire recovery different Mediterranean vegetation types during three years after fire event were analyzed, according to severity categories, integrating use Synthetic Aperture Satellite Radar (SAR) (Sentinel-1) optical (Sentinel-2) image time series. The results showed that forest species shrub/herbaceous are adapted fire, with high efficiency in restoring cover. Differently, ecological vulnerability non-native eucalyptus plantations was found a lower trend observation period. short-wave infrared (SWIR) SAR C-band-based data revealed some characteristics, such as woody biomass structure, recovered at slower rates, comparing those suggested by using near-infrared (NIR) red-edge data. An optimized burn ratio (BRR) proposed estimate map distribution degree recovery.
