For some years it was not possible to obtain data for the number oftrees cut nor the volume harvested in some concessions. For this reason, the averages for the trees/ha/year andvolume/ha/year harvested were estimated using only the available data. Thus several parameters in this tablecannot be used to calculate other derived parameters.• All volume is expressed in official cubic meters.100
