We developed a method for deriving these estimates from readily available forest inventory data by using statistical biomass models and dynamic modelling of litter and soil. Here we demonstrate this method and apply it to Finland s forests between 1922 and 2004. The method was reliable since the results obtained were comparable to independent data. The amount of carbon stored in the forests increased by 29 79 of which was found in the biomass and 21 in the litter and soil. The carbon balance varied annually depending on the climate and level of harvesting with each of these factors having effects on the biomass differing from those on the litter and soil. Our results demonstrate the importance of accounting for all forest carbon pools to avoid misleading pictures of short- and long-term forest carbon balance. carbon inventory forest biomass greenhouse gas inventory litter soil modelling Résumé - Accumulation de carbone dans les forêts finlandaises entre 1922 et 2004 une estimation obtenue en combinant les données de l inventaire forestier avec une modélisation de la biomasse de
