Forests are capable of sequestering carbon through tree biomass and it is important to predict their storage potential given the increase in CO2 from deforestation and illegal mining. The objective of this research was to evaluate the storage of carbon and calorific value based on the aerial biomass of the forest diversity located between 2358 to 2450 masl of the Montane Humid Forest (Bh mo) in the buffer zone of San Alberto-Quilla in the Biosphere Reserve. The forest was located on the eastern Andean flank of Oxapampa in Cerro de Pasco (Peru). Four forest plots with an area of 900 m2 each were evaluated, using the destructive method for trees with a diameter at breast height (DBH) equal to or greater than 10 cm. Species richness, density, diameter at breast height, and aerial biomass (AGB) were determined.
