It was found that bioproductivity increases significantly with age: in young forests (10-30 years old), biomass averaged 25 t/ha, in middle-aged forests (40-60 years old) - 65 t/ha, and in mature forests (80-100 years old) it reached 120 t/ha. The correlation analysis showed a high dependence of biomass on tree diameter and height, with the strongest relationship between stem volume and wood phytomass (r=1.00). The carbon-absorbing capacity of forests also increased with age: young forests absorbed about 12.5 t/ha of carbon, middle-aged forests - 32.5 t/ha, and mature forests - up to 60 t/ha. In addition, the study found that climatic factors, such as precipitation and average temperature, have a significant impact on bioproductivity. When precipitation fell below 550 mm per year, a 15-20% decrease in biomass was observed. Thus, the results emphasize the importance of sustainable management of Polissia pine forests, given their role in global carbon fixation processes, making them an important tool for combating climate change and environmental challenges.
