“…Our observations were on a green ton basis, and we estimated that the slash had a ~50% moisture content, which was modified to kg. For example, Poltorak et al [26] and Choi et al [27] reported that logging residue produced immediately after logging contains high levels of moisture, ~50 to 60% of the total weight. The soil's BD and K were measured using a 90.6 cm 3 slide soil corer with a 5.0 cm inner diameter and length of 5.0 cm (Eijkelkamp Soil & Water, Giesbeek, The Netherlands) and a mini-disk infiltrometer (3.1 cm tube diameter and 32.7 cm length; Meter Group Inc., Pullman, WA, USA), respectively.…”

Recently, the use of powerful and heavy vehicles for timber harvesting on flat or slightly sloping terrains has been widely expanded to provide safe working conditions and high productivity. However, soil disturbances during ground-based mechanized operations in South Korea are not fully investigated and difficult to avoid. Therefore, we compared the soil displacement and compaction (bulk density and hydraulic conductivity) between two different operations: cut-to-length (CTL) logging with a harvester and forwarder, and whole-tree (WTH) logging with a harvester and skidder. After clear-cutting, severe visual disturbances and rut depths were more prevalent in the forwarding trails than in the skidding trails. The CTL harvesting method created larger amounts of slash (6.9 kg/m2) along the trails than the WTH harvesting did (1.8 kg/m2). We found a significant difference in the compaction between the reference and the track and a negative correlation between the slash quantity values and the percentage increase in compaction. Our results showed that using skidding extraction can cause more severe impacts than forwarding extraction. Thus, these results may be helpful in understanding the influence of ground-based CTL and WTH harvesting operations and achieving best practices to minimize the environmental impacts on soil.
