Over- and under-bark volume estimation of European larch timber produced by mechanised harvesting in Czechia

Popis výsledku v původním jazyce

In Czechia, harvesters contributed 43% of the total annual timber production in 2022. It is assumed that harvester technology will continue to be used intensively in the future, even though there is a change in the tree species composition of forests after the recent bark beetle outbreak and an increase in the use of close-to-nature forest management. The aim of this study was to analyse the over- and under-bark volume estimates of European larch timber produced by a harvester in Czechia. This study used the M3s price category for volume estimation. This volume was compared with the M3toDE price category. The M3toDE price category underestimated the over-bark volume by 5.59% compared to the M3s price category. However, for use in forestry practice in Czechia it is currently necessary to use the M3toDE price category. Therefore, the M3toDE price category was used to compare under-bark volumes according to different bark deduction methods. Differences were found between all the five methods investigated. Understanding this sub-issue will help in training operators, acquiring comprehensive knowledge about the functioning of harvester software and maximising the economic effect of the sale of larch timber.
