DYNAMICS OF CHANGES IN THE FOREST FUND OF NATURAL RESERVE «DREVLYANSKY»

The analysis of the dynamics of changes in the areas of land categories and the average tax indicatorsof the Drevlyansky Nature Reserve is carried out. It is established that the area of the forest fund of theReserve has not changed. There was an increase in the area of forest land covered by 106.9 hectares andin 2018 is 15021.1 hectares. The area of lands not covered with forest vegetation decreased by 107.5 ha, ofwhich the area of non-closed forest crops decreased by 104.5 ha. With a decrease in the area of forest landsby 0.6 ha, the area of non-forest lands (swamps) increased accordingly. There were also minor changesamong the taxonomic indicators of the stand. The average age of the stand increased by 5.5 years (from1.5 years the age of hanging birch increased to 6.5 years of aspen). The average credit rating decreased by0.16 (from 2.45 to 2.61). The largest decrease occurred by 0.8 in pine banks (from 1.8 to 2.6). The highestquality in Canadian poplar. There was also an increase in average fullness: from 0.78 in 2008 (mediumstand) to 0.81 in 2018 (high stand) the largest increase in fullness occurred in hanging birch — by 0.05(from 0.73 to 0.78 ). There are also stands with a density of 1.0, the area of which decreased in 2018 compared to 2008 by 107 hectares (from 356.8 hectares to 346.1 hectares). The total stock of the stand increasedby 12.5% and amounts to 4321.83 thousand m3. The increase in area occurred from 9.1% (3.06 thousandm3) in common oak to 37.7% (28.98 thousand m3) in hanging birch. The increase in the average stock per1 ha of forest vegetation is from 1.11 m3 / ha in aspens to 32.52 m3 / ha in hanging birch. This analysisof changes in land categories and average tax indicators is necessary to develop an effective action planfor forest conservation, increase the forest cover of the Reserve and provide future status of old growthforest.
