Reproduction of coniferous stands Complex logging

Abstract

The forest management system should have the status of comprehensive felling, providing for the simultaneous implementation of elements for the harvesting of ripe and perestroika wood and felling of care (rarefaction) in the plantation. Complex logging should include the development of deciduous and deciduous-coniferous forests, when in one step the predominance of the spruce element in the stand with its high subsequent growth energy within the I–III classes of bonitet and resistance to forestdestroying factors is ensured. In order to form spruce trees from altitudinal undergrowth up to 4 m (average – up to 1,5–2,0 m) with ensuring the productivity of the stand according to class I-II of the current bonitet, it is sufficient to preserve the undergrowth within 1,5–3,0 thousand copies/ha. This approach allows for better quality Subsequent rarefactions at an early stage with a selective selection method will contribute to the cultivation of spruce trees from trees of all categories (undergrowth, self-seeding) with the best hereditary properties, excluding their oppression. Such a method of complex logging will make it possible to form valuable spruce plantings during logging on a selective basis for the breed and quality composition of the spruce element. Complex logging is not considered in the current Russian legislation, which is due to the lack of sufficient scientific justification and regulatory support. Long-term research at a stationary facility allowed us to follow the formation of plantings after complex logging and develop scientifically based criteria for their implementation.
