In this study, forest biomass carbon storage changes were estimated for a case study area of Caykara planning unit based on forest inventory for the years 1971 and 2010 using tree species dependent biomass expansion factors. The outputs were handled in the context of forest dynamics represented by temporal and spatial changes of land cover. Quantitative evidence showed that there were drastic changes of carbon storage in above and below ground forest ecosystems from 2.34 Tg carbon to 3.91 Tg carbon between two periods. Carbon sequestration rate was 1.37 Mg carbon yr(-1) ha(-1) for living biomass due mainly to the increase of forest area and growing stock and its quality. On the other hand, such a rate of increase in carbon storage was not influenced negatively by an almost tripling in the total number of patches from 406 to 1,445 in the same period.
