Two equations were generated for determining the biomass and carbon in Pinus montezumae and Alnus jorullensis HBK ssp. jorullensis of ecological important species of the forests of the Sierra Nevada in the State of Mexico. The equations were determined are of the form Y= bXk, where Y is the biomass content or carbon (kg) and X normal diameter (DN) in cm. For estimating the model and k values for each species, Pinus montezumae 15 trees and 16 Alnus jorullensis ssp. jorullensis were used. In Pinus montezumae the highest percentage of biomass was estimated at 77.07% including the stem stump, while the branches and foliage showed 8.45 and 9.01%, respectively, biomass and DN trees the adjustment is obtained by k parameters of the proposed model (B= 0.013 DN3.0462) with R2= 0.9909. For the case of Alnus jorullensis ssp. jorullensis the same as the highest percentage of biomass was estimated at 63.77% including the stem stump, while the branches and foliage showed 20.99 and 11.46%, respectively; with biomass and tree DN setting the parameters of the proposed model by k (B= 0.0195 DN2.7519) with R2= 0.9311 was obtained. After analyzing the carbon content in the sample of each species, the equations for Pinus montezumae C= 0.0065DN3.0484, with R2= 0.9914, while for Alnus jorullensis ssp jorullensis was adjusted. C= 0.009DN2.7522 con an R2= 0.9313.
