Forest plantations of the foothills of the North Caucasus and their environmental and economic assessment
Abstract
Foothill forest plantations of the Karachay-Cherkessia Republic are considered in this paper. The plantations are created by sowing and planting, strip or group tree espacement, both clear and mixed in composition. Thirteen permanent test plots with a total area of 4 hectares were laid. Six of them were laid in the Cherkessk-Elista-Volgograd State Forest Protection Zone (the Stalin’s Nature Transformation Plan of 1948). Complete enumeration of trees was carried out on each trial plot, defining their preservation, condition and quality. Models (from the trees of medium diameter and height) were selected. The graphs of growth progress in height and diameter were constructed. The calculation of barrel and stock volume was based on special tables. Environmental and economic assessment of the plantations (Kuban forestry, the Karachay-Cherkessia Republic) was carried out. The assessment was based on the methodology by V Tarankov. The calculation of carbon reserves was carried out by the calculation and measurement method using special tables. The current growth of plant phytomass was calculated through the intensity of carbon sequestration. Assessment of carbon dioxide absorption and oxygen evolution was carried out by the calculation method. The research is based on the method of comparison and analysis using variation statistics, which significantly improved the reliability of the data. For the first time, the experience of creating forest plantations in the foothills of the Karachay-Cherkessia Republic is summarized. The research makes a basis for planning and reconstruction of artificial stands in the foothills of the North Caucasus (eastern part).
