This work deals with comparison of aboveground biomass of 9-year-old silver birch and European beech stands (treatments) growing on former clearing. At the beginning and the end of the 9th growing season, height of beech (artificial regeneration) and DBH of birch (succession) was measured. To estimate the aboveground biomass of the beech and birch treatments, allometric equations based on the data of the sample trees were used. Only 47% and 46% of 10,000 planted beeches was found at the time of measurement. At the same time, density of birch in succession treatment was 10,900 plants per ha. Dominant height of birch was about 8 m, whereas maximum height of planted beech was under 3 m. Estimated total aboveground biomass of birch and beech stand were 26.8 (stem – 18.4; branches – 5.5; leaves – 2.9) and 0.8 (stem – 0.44; branches – 0.2; leaves – 0.16) t.ha-1, respectively. More biomass means more carbon sequestration – thus more environmental benefits provided by birch stands. It can be concluded that birch should be widely used in the process of reforestation after disasters.
