Transformation of derivatives birch forests tending cuttings Belarusian Poozerie at the root of forest formations

Abstract

The research features in derivative thinning birch on the territory of Begoml forestry. As a result of this species in the category of economically valuable plan tations converted 70.8 hectares. Dominated by through passage thinning. As a result of their conduct in the economically valuable plantation transferred 45% of the total transferred stands, cleaning – 28%, the minimum ar ea of derivatives birch converted into economically valuable after lightening – 7.5%. The intensity of thinning varies from mild (15%) to strong (40%). Experience the transformation thinning birch stands of Belarusian Poozerie in indigenous forest formations on the territory of five forest districts showed that carrying out lightening in birch bilberry and sorrel types of forest facilitated the transfer of these areas in covered by sp ruce forest area. After the tassel in birch polytric, sorrel and fern plantations have also been translated in a wooded area by coniferous trees.
