Objects of research - ripe fir-oak, pine-beech and beech tree stands and young generation of the main and concomitant wood species, which are formed in different ways of head scarring. The purpose of the work is to develop a system of forest and technological measures aimed at forming the formation in the Carpathian region of variety of mixed woodlands with a horizontally and vertically closed structure based on natural seed renewal for the introduction of a selective, close to the nature of forest management. Methods of research - comparative ecology, forestry, forest-taxational, variation statistics. In the work, the methods and mechanisms of re-forming of single-tree stands in the diverse are covered, a biocenotic concept of introducing in the Karpatsk region is close to the nature of forestry. It has been established that during the reproduction of fir-oak trees of special forests, only oak is ordinary. Intensive cutting reforms after seedlings in oak and subsequent regular care for its young generation, which consists in protecting the competition from plants on the side of the plants, undergrowth, the growth of other breeds, incl. and a white fir, provides a successful reproduction of indigenous fir-oak tree stands. The natural renewal of pine-beech tree stands best passes in the case of a two-step uniform gradual scarring, in other ways of scarring (soil-gradual, wagner) in the reproduced tree stands, the forest of the forest has a significant advantage over the pine forest. The most effective for the reproduction of ripe beech stands and the formation of a young generation of beech is a uniform gradual two-step fusion. Key words: main rubles, cutting reform, natural renewal, formation of fir-oak, pine-beech, beech tree stands. Product Description popup.authors popup.nrat_date 2021-03-31 Close
