“…In Mexico 57% of mortality is caused by the poor quality of the plant (Prieto et al, 2016), also another important factor are the deficiencies that occur during the planting process (Burney et al, 2015), for example, if the strain becomes too deep the plant will suffocate and if the strain becomes shallow, the roots could be left on the surface and the plant will dehydrate, in addition, covering the stem with too much soil reduces the vigor of the plant and makes difficult its access to water (CONAFOR, 2010). For the proper management of forests in Mexico, including areas planted with the main commercial tree species, different silvicultural systems are employed in order to ensure the regeneration of the site: The Mexican Irregular Forest Management Method (MMOBI) and the Silvicultural Development Method (MDS) (Solís et al, 2006;Pérez-Verdín et al, 2009;Pérez-Rodríguez et al, 2013). The former is used in forest stands with a high tree species richness, and the latter in stands dominated by one or two tree species of pine (Hernández-Díaz et al, 2008).…”
