PROBABILITY OF MORTALITY IN CASUARINA TWO YEARS AFTER THE FIRE AT THE PIEDMONT OF THE TLALOC VOLCANO, STATE OF MEXICO, 2017

In 2017, at the foot of Tlaloc volcano, occurred largest forest fire in State Mexico (2500 ha), with surface and crown (canopy) phases, on plantations various species types vegetation. Studies effects fires trees serve to define mortality whether or not restoration will be required an affected area. The hypothesis was: greater intensity severity smaller size trees, probability mortality. objective study was establish dasometric variables that influence both resprouting Casuarina equisetifolia L. by fire. conducted Experimental Forestry Station “Las Cruces” (Universidad Autónoma Chapingo, Mexico). 2019, 442 (15 sites 100 m2) were sampled 50 ha Records made alive dead, normal diameter, bark thickness, height, height base original crown, scar trunk, scorch presence resprouting. statistical analysis consisted logistic regressions, using Proc Logistic procedure SAS program. average tree 63 %. variable directly related (p ≤ 0.05) above trunk. inversely were: diameter thickness. For probability, there inverse relationship thickness It is concluded casuarina a sensitive species.
