FLORES, Andrés et al. Potential of restoration of coniferous forests from germplasm transfer zones in Mexico. Rev. mex. de cienc. forestales [online]. 2021, vol.12, n.63, pp.4-27.  Epub 26-Mar-2021. ISSN 2007-1132.  https://doi.org/10.29298/rmcf.v12i63.813.

Forest land restoration requires data related to the number of seedlings produced and the level of soil degradation. Decision makers need to know the efforts of the national reforestation program as a driver of ecosystem restoration in Mexico. To assess the restoration potential of conifer forests and reduce land degradation by Germplasm Movement Zones (GMZ), priority zones for restoration were compared with areas that possess most effective restoration efforts: survival rate of planted seedlings, number of nurseries (N), Germplasm Production Units (GPU) and Germplasm Banks (GB) with data from Conafor corresponding to the 2016-2018 period. It was found that 27 GMZ had 7 418 975.30 ha of low-production forest land as priority areas and 9 389 577.70 ha of forest land with medium and low degradation. According to the variables used in the comparative analysis, eight GMZ (XII.4, XII.5, X.3, X.2, XII.1, V.3, XII.2, and XV.1) were identified as restoration potential zones because their priority areas could be totally reforested by using Pinus and Abies species.
