Changes for fast-growing forest management have an immediate effect on carbon stocks and the regional carbon sequestration rate, by incorporating carbon dioxide into biomass plant, therefore it is essential to know their condition and response to management, for proper management. The aim of this research was to evaluate the effect of two silvicultural management methods after 21 years of reforestation, on the carbon stocks in the soil at 10 cm, 20 cm, and 30 cm deep: as well as mulch, dead wood, roots, and aerial biomass, in the Sierra Norte de Oaxaca. Sampling was carried out in two sites with management: (1) silvicultural development method (MDS) and (2) Mexican irregular forest method (MMOBI) (low intensity) and in three natural forests of pine, oak, and pine -oak. Aerial tree biomass, dead wood and roots were estimated by allometric equations and carbon was calculated. Mulch and soil were measured on an automatic analyzer. The MMOBI method presented a higher C content in soil and litter (127.89 Mg C ha-1), but the largest carbon reservoir was found in the tree biomass of the pine-oak forest (383.9 Mg C ha-1). The MMOBI can be a management alternative that favors carbon stocks in the soil, while the pine-oak forest demonstrates a potential as a tree carbon stocks at an age over 40 years old.

Keywords : oak forests; pine forests; pine-oak forests; MDS; MMOBI.
