Morichales are strategic ecosystems because they store more Carbon, contribute to the mitigation of GHG, climate change and have been little studied in the Colombian Orinoquia. Therefore, the objective of this study was to estimate the Carbon stock in biomass, necromass and soil of a morichal conserved from the Colombian highlands. Three sectors were selected according to their phenological stage, senescent, adult and juvenile palms, in each sector 2 transects were established and they were subdivided into subplots identified as interior (morichal), ecotone (transition between savanna and morichal), in which the samplings. Biomass was estimated with allometric equations, individuals of M. flexuosa with DBH> 10cm, arboreal and shrub species with DBH> 2.5cm and pasture samples were taken in ecotone; the fallen and standing necromass was estimated with allometric equations, and particulate necromass samples were taken; the biomass and necromass values ​​were multiplied by the carbon factor. The soil was sampled at two depths 0.0 - 0.3 m and 0.3 - 0.6 m, the percentage of carbon and the apparent density were determined for soil C stock. The results show that the carbon stock in the morichal is 590.8 tC / ha, where the soil is the compartment with the highest contribution with 436.5 tC / ha, followed by biomass with 119.4 tC / ha and finally the necromass with 35.0 tC / ha. These results show the role of morichales as natural carbon sinks and the importance of their conservation for mitigating climate change, as well as providing other economic and environmental benefits for the community.
