Abstract

RODRIGUEZ-LARRAMENDI, Luis Alfredo et al. Estimation of the biomass and stored carbon in community forest of La Frailesca region of Chiapas, Mexico. Rev. mex. de cienc. forestales [online]. 2016, vol.7, n.37, pp.77-94. ISSN 2007-1132.

Twenty-two 500 m2 plots (two for each ejido) were selected in 1 ejidos of La Frailesca region of Chiapas in order to estimate the biomass and accumulated carbon in pine (Pinus maximinoii), oak (Quercus robur), holm oak (Quercus rugosa) and Mexican weeping pine (Pinus patula). The height (H), age (years) and normalized diameter (ND) of 358 trees were determined in these plots. Regression equations between the accumulated biomass (BMt) and the age of each tree were adjusted. The adjustments were statistically significant for the exponential model y=b·ec·x. This study proves that the total accumulated biomass can be estimated based on the age of the tree, and that the largest accumulation of both biomass and carbon occurred in the pine forests, and the lowest, in the oak forests; this is due to their physiological status, as the latter trees are younger. Pine trees had a storage of 158 Mg ha-1, followed by holm oaks, with 17 Mg ha-1; the species with the lowest value was oak, with 5.9 Mg ha-1. Of all the studied sites, the forests of the “24 de Febrero” ejido had the highest potential for carbon capture.

Keywords : Biomass accumulation; aboveground biomass; root biomass; community forests; carbon capture; allometric relationships.
