About forests using of Arkhangelsk region of the Arctic zone (European part)

Forestry assessment of the effectiveness of various cuttings, which were used in the forests we studied, was carried out. It was found that in a number of clear-cuttings 15-20 years after harvesting there are at least 1.5-2.5 thousand spruce-dominated self-seedlings and undergrowth. After felling there are many spruce and pine undergrowth, which are categorized as unreliable. In spruce forests clear-cutting areas often carried out (clear-cutting), in pine forests mainly forest maintenance thinning. In pre-harvest spruce the height growth reaches 25 cm already in the 2-5th year after harvesting, while in post-harvest spruce the growth averages 3-6 cm per year. With increasing age of felling, the number of settled specimens decreases, and after 10-12 years it is not observed at all. The duration of this process indicates the need for serious attention to the preservation of the maximum number of pre-generation undergrowth during harvesting. Is one of effective recommendations it will reduce the afforestation period of the clear-cutting areas. In addition, it is necessary to carry out additional measures to increase the success of reforestation on clear-cuttings by means of soil mineralization.
