7th Workshop on Forest Fire Management - EARSeL, European ...

Monitoring post-fire vegetation regeneration of the 2003 burned areas in Portugal using a time-series of MODIS enhanced vegetation index 249
sample grid was created. Inside the burned areas the grid size is 500 m. The
values inside the burned areas will provide information related to pre and
post-fire situation, but it’s also important to have some control plots outside
the burned areas in order to understand the vegetation dynamic without
fire. Therefore, a 1000 m sized sample grid was created outside the
burned areas, but only in the same Corine classes has the ones that exist
inside. Next we created time-series for the fire and control area at each of
the three sites using an IDL script to extract the EVI values and plotted EVI
means and standard deviations.
