Temperate forests in Mexico have been reduced due to land use change for agriculture, illegal logging, forest fires, and pests and disease. However, the reforestation program (RP) is a strategy to increase forest areas and decrease forest land degradation. The aims for this work were: to assess the reforestation potential for restoring degraded areas with Pinus pseudostrobus, P. engelmannii, P. montezumae, P. greggii, P. arizonica y P. durangensis; and to define the efforts of reforestation program for species production. The potential areas for reforestation and the degradation for forest lands were estimated. Also, the abilities of RP for seedlings production of conifers based on the number of nurseries established (N), germplasm production units defined (GPU) and germplasm banks (GB) installed were analyzed. The results showed that target species could reduce 57.52 % total area degraded. The annual areas estimated for restoration were: 15 458.97 ha (P. pseudostrobus), 8 685.33 ha (P. engelmannii), 8 413.30 ha (P. montezumae), 7 618.73 ha (P. greggii), 3 081.18 ha (P. arizonica) and 1 400.10 ha (P. durangensis). For RP, the efforts had a significantly impact, i.e., five states had 50 % out all N (113), and around 30 % GPU (22) and GB (4). This information is essential to plan restoration actions for target species.
