Moisture Content of Fresh Scots Pine Wood in Areas near Damage Caused by Harvester Head Feed Rollers

By damaging bark, mechanized harvesting deprives wood of its natural mechanical barrier. This study concerns the effect this damage on changes in moisture content that occur near damaged areas Scots pine (Pinus sylvestris L.). was carried out using 45 randomly selected 11 m long logged stems. Additionally, bark thickness depth measured. To determine influence location and region, samples were collected from two sections. The first located one meter above log’s base, while second end log. Two increment cores taken by a Pressler borer each section: zone undamaged zone. average base log 11.2 mm, which decreased to 1.8 mm top depths caused feed roller spikes sections 3.9 3.8 respectively, indicating there no significant damage. (DW) had about 13 percent lower than those (UDW). difference statistically significant. We observed greater mean closer for both One log, between DW UDW 9.8 percentage points, insignificant. contrast, significantly (−16%)
