Abstract: | Not only wildfire damage, but the failure of post-fire forest restoration is also one of the major threats for the conservation
of forest ecosystems. Therefore, it is required to estimate wildfire damaged potential and recovery capacity to orientate
the management of a post-fire community. The aim of our research is to estimate the resistibility against wildfire and the
post-fire regeneration capacity by merging field observation data with Terra/ASTER Level1B satellite data and a fire area
simulation model (FARSITE). As a result, the resistibility against wildfire and the post-fire regeneration capacity were high
in the high prior-fire normalized differential vegetation index (NDVI) areas, where the trees had been thriving. Also, after
the fire, the well developed surface soil (the A horizon) provided a good environment for resprouting from unburned stumps
and the rhizome. It is suggested that the thriving forests have a strong resistance against wildfire and have large regeneration
capacity. |
