Abstract

The formation of birch forests is widespread in the Republic of Belarus. The article describes the characteristics of the current state of birch forests in Belarus, taking into account geobotanical zoning. The forested area of birch forests is 23.4%. The greatest distribution of birch forests is noted in the north and northeast of Belarus. Highly productive birch forests prevail, 72.4% with Ib – II bonitet classes. The stands of the birch formation are mainly of medium density – 0.6–0.7 (71.2%). Completeness for geobotanical districts ranges from 0.65 to 0.69, for regions – from 0.65 to 0.71. In the age structure, the most significant share is occupied by middle-aged stands – 53.6%, young stands are 15%, ripening – 16.8%, ripe and overmature – 14.2%. The most common types of forest are oxalis birch forest, bracken birch forest, bilberry birch forest. In oxalis and bilberry birch forests, a sufficient amount of renewal of bedrocks was noted.
