Linking fire ignitions hotspots and fuel phenology. The importance of being seasonal
Fire ignitions tend to be aggregated in time and space creating a clustered spatio-temporal pattern that is mainly
driven by climatic factors and the availability of ignition sources. The aim of this work is to identify the spatiotemporal
distribution of wildfires hotspots in Sardinia (Italy) during 2000–2013 and to relate their dynamics
with remotely-sensed NDVI-based fuel phenology patterns. We considered eleven bi-weekly time frames (TFs)
and used kernel density (KD) estimation to spatialize the corresponding fire ignitions. Then, to identify zones of
