Stem Volume Tables by Height Classes of Willow Trees in the Northern Taiga Region of the European Part of the Russian Federation
Journal Title: Lesnoy Zhurnal (Russian Forestry Journal) - Year 2021, Vol 9, Issue 6
Abstract
In order to improve the accuracy of forest inventory works, tables of stem volume by height classes of willow trees in the northern taiga region of the European part of the Russian Federation were created. Forest inventory standards have not previously been developed for this species in the northern taiga region. The analytical technique proposed by I.I. Gusev in 1971 for spruce forests of the European North was used in compiling the height class volume tables. It was later adopted for the description of other tree species as well. Diameters and heights of trees were measured at 41 sample plots laid out in the Verkhnyaya Toyma and Arkhangelsk forestries of the Arkhangelsk region; 105 model trees were sampled. In most cases, sample plots were laid out in mixed plantations with the predominance of willow. The data obtained on the sample plots served to determine the parameters of the height class scale. The information source for stem volume of willow trees used to be the stem volume tables for aspen trees. A comparative analysis of the tables compiled for willow trees stems with the tables for aspen taken from the Forest Valuation Handbook for the Northeast of the European part of the Russian Federation was carried out. The analysis shows significant discrepancy in the scales for willow and aspen. The use of aspen height class volume tables for willow leads to a systematic overestimation of wood volumes. Tables of stem volumes by height classes of willow trees are used to determine stand stock with the enumeration data by 4-centimeter diameter classes. The developed tables meet the forest practice requirements. The volume tables by height classes are used to calculate timber reserves when laying out sample plots; to determine the damage level in case of stand damage; and for other practical purposes.
