AGUIRRE-CALDERON, Oscar Alberto  e  JIMENEZ-PEREZ, Javier. Carbon content evaluation in southern forests of Nuevo León. Rev. mex. de cienc. forestales [online]. 2011, vol.2, n.6, pp.73-84. ISSN 2007-1132.

The acknowledgement of the importance of environmental services that forests provide and the need to count on reliable methods to assess them are the reasons to accomplish the actual study, whose objectives were to develop methods and practical tools to estimate the carbon content of some forests at the South of Nuevo León State. Biomass equations based on the normal diameter (called DBH at height 1.30m) of the tree form for Pinus pseudostrobus, P. teocote and Quercus spp. were developed in temperate forests of Southern Nuevo Leon (NL). Likewise, it was estimated the carbon content of the tree species under study, using an organic carbon analyzer. Results allowed the construction of rates, biomass and carbon content tables, which were assessed by the amount of carbon in the tree component of mixed forests of pine-oak, oak-pine and pure pine stands. The carbon per cent content in dry weight in Pinus pseudostrobus trees was 50.35, in P. teocote 47.78 and in Quercus spp. 48.43. Carbon content site index tables were constructed for pure three pine species stands. Results of carbon content evaluation in different forest types were: pine-oak 45.24 Mg ha^-1, oak-pine 64.20 Mg ha^-1 of P. pseudostrobus 73.18 Mg ha^-1 and P. teocote 47.01 Mg ha^-1.
