Assessing the potential for natural reforestation after clearing cuttings in the territory of the Tyumen forestry

A survey of forest areas passed through cuttings on the territory of the West Siberian subtaiga-forest-steppe plain forest region was carried out. Peculiarities of seed regeneration of Scotch pine in clear-cut areas are considered. It has been established that viable, small and medium height undergrowth, 0.35-0.7 m high, of medium density, without damage - 45-55% of the total amount of undergrowth, aged 3-4 years, prevails in the clearings. There is a resumption of the accompanying tree species - birch in the amount of 200 pieces / ha with an average height of 0.7 m. core rot. According to the method of accounting and evaluation of natural reforestation, the identified amount of viable undergrowth of Scotch pine in the studied clearings indicates that natural reforestation at this stage of development is not satisfactory in all areas. As a result of the analysis carried out, forestry activities related to the promotion of natural reforestation were outlined.
