It entails a modification of plant structures in place. In the Mediterranean region, the current vegetation is conditioned and adapted to this fire system. The analysis of post-fire response of Chamaerops humilis L., (Arecaceae) species widespread in the Western part of Algeria and in the most of the matorral of Tlemcen shows that the determinism of stipes height (H) explains the variations of average lengths of regenerated leaves (M) (R2 = 64%). Furthermore, researchers notice that there is a highly difference significant (p = 0<0.05) at the power recovery in the phenological post-fire which depends on the height of the stipe; it is 100% for class 1; 93% for class 2; 58.33% for class 3 and only 5.55% for the class 4. This response of Chamaerops humilis L., is a damaging caused by fire, it shows the resistance of this species in this disturbing phenomenon as evidenced by the strong recovery of their workforce (81.25%).
