Description
Summary:As climate change becomes a more and more pressing issue, the role of forests as carbon sinks will increase further. Carbon sequestration models can be a useful tool in planning future management strategies, but only if they are properly calibrated for the ecosystem in question. In our study we used data from the literature and other publicly available data for the parameterisation of the CO2Fix model and compared the model results to reference estimations based on data from a field survey carried out in autumn 2015 in some beech and hornbeamdominated stands of Haragistya-Lófej forest reserve (Aggtelek Karst). Due to the less favourable site conditions, effects of earlier management and the relatively young age of the stands the carbon content of the biomass was found to be somewhat lower than in other beech forests. We also examined the effect of using different mortality settings on the results. The model with ‘no mortality’ settings was found to give the best results, however the performance was species-dependent. The model tends to underestimate the carbon content of the biomass for beech-dominated plots, but the higher the proportion of hornbeam, the higher the chance that the model overestimates the carbon content.
