RT Journal Article SR Electronic A1 Kadlec, Jiří T1 Biological waste by-production costs in forest management and possibilities for their reduction JF Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis YR 2015 VO 52 IS 5 SP 7 OP 12 DO 10.11118/actaun200452050007 UL https://acta.mendelu.cz/artkey/acu-200405-0001.php AB Biological wastes in forestry were observed from view of their by-production in silvicultural and logging operations. There were identified points where biological waste was produced in this paper, waste costs ratio for silvicultural and logging operations and were made suggestions for reduction of these costs. Biological waste costs give 34.4% of total costs of silvicultural operations and 30% of total costs of logging operations. Natural regeneration and minor forest produce operations are opportunities for reduction of these costs.
