Resumen: The assessment of fire effects in Aleppo pine forests is crucial for guiding the recovery of
burned areas. This study presents a methodology using UAV-LiDAR data to quantify malleability in
three burned areas (1970, 1995, 2008) through the statistical analysis of tree height and Profile Area
Change (PAC) metrics. Significant differences in vegetation height (99th percentile) among the three
fires, with specific maximum absolute differences (D) depending on the fire year, have been identified.
Positive PAC values in 2008 indicate deeper LiDAR penetration, resulting in lower regeneration,
while values close to 0 in 1970 suggest more uniform regeneration. The use of LiDAR metrics and
uni-temporal sampling between burned sectors and controls aids in understanding community
resilience and identifying recovery stages in P. halepensis forests.
