    The objective of this work was to estimate the biomass and calculate the expansion factors of Pinus pseudostrobus, Pinus teocote, and Quercus spp. in the Southern forests of Nuevo Leon, Mexico. 8 to 16 trees of each species were cut down and its humid weight was determined, in field samples were taken to determine the relation dry weight/ humid weight (Ps/Ph), with which the total dry weight was calculated for each tree. Biomass models were adjusted. The equation that best adjusts was, where y is the aerial biomass, E exponential, D dbh, a, b parameters and 1.3 constant. In all the cases the R2 was greater than 0.89 and the standard error (Sx %) smaller than 30.9. The biomass was estimated by forest type according to the data of 1,053 trees obtained from the 400m2 sampling plots, being for the pine forest 125,333 t of biomass per hectare (tB·ha-1), in oak-pine 112.593 tB·ha-1 and in pine-oak 96.688 tB·ha-1. Biomass expansion factors were determined (Fexp), the mean values were 1,373 for Pinus pseudostrobus, 1,394 for P. teocote and 1,511 for Quercus spp.
