The objective of this work was to develop allometric equations in order to estimate the biomass by thickness fractions of the regeneration of Arbutus arizonica, Juniperus deppeana, Quercus sideroxyla and Pinus cooperi trees of the Forest Management Unit (1008 Umafor) in the state of Durango. The data of 114 individuals (25, 29, 30 and 30, respectively) was used, collected through a destructive sampling, for adjusting the models. The additivity of the equations used to estimate the biomass is assured by the simultaneous adjustment of all equations, with the statistical procedure called 3SLS (Three-Stage Least Squares). The developed models make it possible to estimate the biomass in dry weight of the components, total weight, leaves, twigs (< 0.5 cm), thin branches (0.51 - 2.5 cm), thick branches and trunk (> 2.51 cm). The allometric equations with the best fit corresponded to the total weight, with adjusted coefficient of determination values of 0.97, 0.94, 0.95 and 0.97 for Arbutus, Juniperus, Quercus and Pinus cooperi, respectively. In general, the equations showed a satisfactory adjustment in each of the fractions; they allow non-destructive estimates of biomass by category of thickness of the regeneration of the four studied species, which will improve the predictions of biomass and carbon storehouse by fractions in the forests with the presence of the four studied taxa.
