The objective of this study was to determine strength classes of Scots pine wood, depending on different initial stand density and thinning intensity in Scots pine experimental plots according to EN 338. The problematic question is how thinning intensity and different spacing could affect pine wood strength classes? This topic is important to get knowledge about influence of thinning on wood quality. Wood quality of Sitka spruce was determined of 5 different spacing in Northern Ireland (Moore and etc. 2009). Wood quality of Sitka spruce, Norway spruce and Douglas fir of different time’s thinned stands was determined in Republic of Ireland (Krajnc and etc. 2019). Douglas fir strength classes was analyse in Wallonia, Southern Belgium (Henin and etc. 2018). This study shows differences of wood quality in Scots pine experimental plots in forest land and agricultural land. Initial stand density and thinning intensity is the main parameters of differences of wood quality.
