Abstract

Abstract During selective felling on the territory of 3.9 ha, 181 m3 of wood, 35% of which is dead wood. Among them, pine (16 m3), spruce (27 m3), birch (8 m3) and aspen (12 m3) were found. The volume of cut viable wood was 118 m3, including 50 m3 of pine, 44 m3 of spruce, 14m 3 of birch and 10 m3 of aspen. The values obtained do not exceed the forest declaration data. To determine the stumps from dead coniferous trees, the following criteria were tested: complete or partial absence of bark, the presence of traces of the vital activity of insect pests and abundance worm dust. Species-specific criteria are proposed: in pine – the presence of rot of the peripheral part of the wood, brown color of sapwood and bast; spruce – the presence of heart rot and wood destroying fungi. In deciduous species, the main criterion for isolating stumps from dead trees has been tested – the presence of wood-destroying fungi, in aspen – heart rot caused by tinder fungi. We recommend using these criteria to resolve legal claims against forest users in the removal and assessment of harvested wood.
