Abstract
The features of carbon sequestration in young pine stand in the Left-bank Forest-Steppe, damaged by surface fire, are revealed according to the standards for assessing the components of the phytomass in stands and by dendrochronological methods, which allowed to quantify the dynamics of carbon sequestration in the stem mass of Pinus sylvestris L. Using standards of P. Lakyda, we revealed that the loss of deposited carbon in the fire-damaged stands was 22–30 % compared with the control. Using dendrochronological methods we have found that the carbon content in the trunks of trees varies during ontogenesis but its trend increases with age. The accumulation of carbon in the stem wood did not significantly differ during the pre-fire period (2006–2010) between the control and the damaged stand. However, during the post-fire period (2011–2017), an increase in the amount of carbon in the stem wood of the pine stand was detected as a result of intensive fall of trees due to which there were the improved lighting and nutrition conditions for trees that remained alive. During the post-fire period, the difference between the mass of carbon in the stem wood on the control and the amount of carbon in the trunk on the damaged trees was 20 %. The rate of carbon sequestration in tree stems fluctuated in the period of ontogenesis and at the same time, its quantity increased with age. However, the indicated increase in the mass of carbon did not compensate for the losses due to fire.
