GALEANA-PIZANA, José Mauricio; ORDONEZ-DIAZ, José Antonio Benjamín  and  CORONA-ROMERO, Nirani. Estimation of carbon content in the Magdalena River basin, Mexico. Madera bosques [online]. 2013, vol.19, n.1, pp.53-69. ISSN 2448-7597.

Carbon content of aboveground biomass of six types of vegetation cover in the Magdalena River basin, located in the conservation land in the Mexico City, was estimated. Hence, a map of cover vegetation and land use to the study area was made; a hierarchical stratified sampling design with distribution systematic with a mesh of sampling sites equidistant of 550 meters was used for field work. The method used for field data collection was based on a nested design, with an intensity of sample of 0,64%. There were generated 52 sites of 3000 m². The vegetation cover that showed the highest amount of carbon stored corresponds to the forest of the the Abies religiosa closed with 163 Mg C ha¹ in average; followed by the Abies religiosa - Pinus hartwegii closed with 107 Mg C ha¹, and Abies religiosa opened with 95 Mg C ha¹; about the covers of Pinus sp., Pinus hartwegii closed with 47 Mg C ha¹; Pinus hartwegii - Abies religiosa closed with 39 Mg C ha¹ and Pinus hartwegii opened with 21 Mg C ha^-1.

Keywords : Abies religiosa; above ground biomass; forest; diametrical structure; Pinus hartwegii.
