Due to the increase in greenhouse gas concentrations and the deterioration of green areas in the metropolitan region of Cochabamba, the San Pedro Mountain range represents an important green area within the urban landscape. Considering the deterioration of the mountain range (loss of vegetation cover), the objective of this study was to estimate the carbon fixation in the different vegetation covers of the San Pedro Mountain range, using biomass estimation methods to contribute to the management of this environmental function. The methodology used was the application of allometric equations in forest and shrub cover. The grasslands were extracted, dried and weighted in the laboratory. The cover with the highest carbon fixation per hectare was the open forest (35.34 tC ha-1) and the one with the lowest carbon fixation per hectare was the grassland (0.89 tC ha-1). It was observed that the area occupied by vegetation cover is important and decisive for the total carbon fixation value. Due to the positive relationship between conservation and carbon fixation, were proposed strategies for the maintenance and strengthening of carbon fixation capacity focused on vegetation restoration and control of anthropogenic pressures.
