CARRILLO ANZURES, Fernando et al. Estimation of biomass and carbon in two arboreal species in the Sierra Nevada, Mexico. Rev. Mex. Cienc. Agríc [online]. 2014, vol.5, n.5, pp.779-793. ISSN 2007-0934.

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= bX^k, 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 DN^3.0462) 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 DN^2.7519) with R²= 0.9311 was obtained. After analyzing the carbon content in the sample of each species, the equations for Pinus montezumae C= 0.0065DN^3.0484, with R²= 0.9914, while for Alnus jorullensis ssp jorullensis was adjusted. C= 0.009DN^2.7522 con an R²= 0.9313.
