The rapid increase in livestock production has generated environmental impacts, such as deforestation, loss of biodiversity, soil degradation and greenhouse gas (GHG) emissions. In Chiapas, GHG emissions have increased especially due to the conversion of forest lands to pastures and livestock enteric fermentation. The removal of atmospheric CO by forestry and agroforestry activities within the livestock production units can significantly reduce the net GHG emissions. The main objective of this research was to evaluate the carbon storage potential in forest areas within a livestock production unit in Villaflores, Chiapas, in order to
know their contribution to GHG mitigation. Twelve sampling plots were established in forest areas and pasturelands to evaluate the carbon stocks in aboveground living biomass, root biomass, litter, dead wood and soil organic carbon.
