CHARACTERIZATION OF ZONES AFFECTED BY THE CAUSAL AGENT OF PINE LITTER FALL IN PUEBLA, MEXICO

Abstract

Puebla is a biodiverse state located in the central part of México, characterized by having broad heterogeneity of altitudes with extensive diversity in climates and types of vegetation, with predominance of conifer and red oak forests. During 2011, defoliations were detected in different pine species in the Sierra Norte region of Puebla, so that the characteristics presented by the sites affected by the pine litter fall were defined with the purpose of contributing to decision making in management plans. Likewise, the climate conditions of the sites affected from 2011 to 2014 were characterized, finding that the sites facing south, with slopes of between 24 % and 87 %, altitudinal distribution between 1969 and 2835 m, were the ones with greatest affectation, finding Pinus pseudostrobus as the species with highest litter fall.
