Abstract
The purpose of the study is to analyze the causes of the unsatisfactory condition and death of pine crops in the forest fund of the Republic of Karelia. The data on the assessment of the state of forest crops in the predominant forest types in the Karelian north-taiga region are presented. The objects of the study are pine forest crops of different ages in conditions of lingonberry and blueberry forest types. A complex of works was carried out at the research sites to assess the condition of pine forest crops. During the accounting work, the survival rate, safety and basic indicators for the transfer of forest crops to forested lands were evaluated. The species composition and structure of the formed young plants in the areas of forest crops were taken into account. It was found that the proportion of dead forest crops from the total area of the surveyed sites is 77% in the conditions of the blueberry type of forest and 8.4% in the lingonberry type of forest. Forest crops of unsatisfactory condition were found on 3.1% of the area in the conditions of the blueberry type of forest, 2.7% – in the conditions of the lingonberry type of forest. The composition of young trees in areas of forest crops of unsatisfactory condition includes 49% of pine in the cranberry type of forest and 26% in the blueberry type of forest. The proportion of pine trees of dead forest crops was 34 and 12%, respectively. The number of pine forest crops in such areas is 256 and 232 pcs/ha, respectively. The projective coverage and species composition of the living soil cover were recorded in the areas of forest crops. 6 species with a projective coverage of more than 10% have been identified.
