Carbon content and its potential sequestration in the forest biomass of San Pedro Jacuaro, Michoacán State. Rev. mex. de cienc. forestales [online]. 2015, vol.6, n.32, pp.7-16. ISSN 2007-1132.

As a result of increased carbon concentrations in the atmosphere and their impact on global climate change it has become necessary to determine the amount of carbon stored in ecosystems, from which temperate forests represent a great potential for capturing it in different deposits (aerial or forest biomass, soil and litter); aerial biomass comprises the stem, leaves and branches. This study took place in the ejido of San Pedro Jacuaro, in the state of Michoacán, because their forests are well preserved and are under management. Two estimates, conservative and real, of carbon content in the aerial or aboveground biomass were carried out. The first varied between 67 and 177 Mg C ha-1, Mg C weighted average of 103.1 ha-1. The second recorded values Mg C 71-198 ha-1, with a weighted average of 129.1 Mg C ha-1; regarding the potential of carbon capture is estimated that the forest fixed 1.54 Mg C ha-1 yr-1, corresponding to 5.65 Mg CO2e ha-1 yr-1 and in 1 842 has, making it possible to estimate that can potentially do a total of Mg C 2 837 yr-1, equivalent to 10 401.16 Mg CO2e yr-1. These results suggest that the study area is attractive for carbon sequestration projects like REDD+.
