During selective felling on the territory of 3.9 ha, 181 m 3 of wood, 35% of which is dead wood. Among them, pine (16 m 3 ), spruce (27 m 3 ), birch (8 m 3 ) and aspen (12 m 3 ) were found. The volume of cut viable wood was 118 m 3 , including 50 m 3 of pine, 44 m 3 of spruce, 14m 3 of birch and 10 m 3 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.
