Background: Seedling growth and survival depend on seedling quality. However, there is no experimental evidence showing that the seedling dimensions of the abundant, economically important and widely distributed tree species , , , , and and their hybrids effectively improve survival and growth in reforestations and plantations in Mexico. Therefore, the aim was to evaluate the influence of initial morphological parameters of 2,007 nursery seedlings of these species and their hybrids on their growth and survival 44 months after planting in the Sierra Madre Occidental, Mexico.

The objective of this study was to compare the diameter increment, biomass and carbon accumulation in a plantation of and a naturally regenerated stand. The data were collected from 32 circular plots of 100 m (16 plots in the planted site and 16 in naturally regenerated area).
