TY - JOUR A1 - de Miguel-Díez, Felipe A1 - Purfürst, Thomas A1 - Acuna, Mauricio A1 - Tolosana-Esteban, Eduardo A1 - Cremer, Tobias T1 - Estimation of conversion factors for wood stacks in landings and their influencing parameters: a comprehensive literature review for America and Europe T2 - Silva Fennica N2 - In commercial transaction of stacked roundwood, the estimation of the stack net volume plays a key role. One generalized method to determine the net volume is using conversion factors that relate the gross and net volumes. In this literature review the developed methods to estimate the conversion factors as well as their influencing parameters were analyzed based on 153 references from America and Europe. According to the results, 48 different methods (including their variants) for estimating the conversion factors were developed. The newest methods enabled their accurate determination inexpensively, e.g., photo-optical methods or 3D simulation models. The analyzed references revealed that 30 parameters influence the conversion factors. Based on this comprehensive review, each stakeholder involved in the roundwood supply chain can know which method is used for estimating the conversion factors in the analyzed territories and which influencing parameters should be considered when purchasing roundwood in order to accurately assess the solid wood content in the stacks.
