Modern structure of Belarusian Poozerye forests

Abstract

The territory of Belarusian Poozerye has its geomorphological features that determined the history of the formation of the region. In the glacial period there were significant changes in the environment, which is reflected in relief, soil, climate and vege tation cover Poozerye. Currently, there is also the transformation of vegetation as a result of anthropogenic impacts on the forest. Proposed southern boundary of the Poozerye with the geobotanical, physiographic, landscape and other complex natural and special zoning and given the division of forestry institutions of Belarusian Poozerye on geobotanical subzones, counties and districts. To identify the features of the region were analy zed materials from the Stat e forest inventory. The result revealed that the species composition of forest of Belarusian Poozerye differs from the average in the country. This region is dominated by small-leaved crops, which account for about 50% of the forested land. Birch plantations occupy 30.1%, but 79% of them are derivative. In terms of age classes dominated by middle-aged stands – 43.5%. In terms of value classes dominated highly value plantings – 83.1%, up 3.6% unproductive. The average yield class – I,8. On the territory of Poozerye dominated srednepolnotnye plantings – 64.8%. Average density of 0.7. In the context of a series of forest types dominated by wood sorrel, the share of which is 15.8%, al-so occupy a significant share of bilberry (14.7%), mossy (14.3%) and ferny (12.5%). Slightly presented cowberry, herbal and nettle series of forest types (less than 1%).
