The aim of this study was to investigate the aboveground biomass and carbon stocks stored in the biomass on the shrublands of Kermes oak (Quercus coccifera L.), which is a very common species within the maquis vegetation of the Mediterranean Region in Turkey. To this end, the aboveground biomass components (branches, leaves and stems) were cut and collected from 1 m(2) plots in 10 study sites with 3 replications and they were weighed separately. Furthermore, carbon concentration in the biomass components was measured. Then, biomass and carbon stocks in the study sites were calculated taking account of the canopy cover. The carbon concentration was found as 51.14% for leaves, 49.15% for branches and 48.56% for stems. The weighted average carbon concentration of the aboveground mass was found to be 49.27%.
