Scots pine (Pinus sylvestris L.) is the basic forest species in Poland. Almost 60% of the forests in this country are pine forests. In recent years, about 40 million cubic meters of wood have been harvested in Poland from pine forest (Mirski et al. 2020a). Due to the ease of access of this species, pine is used as wood and in a circular form e.g. structure supports, hollow wood or supports (Sevik 2015). The quantity and availability of pine material makes it the most universal material in sawmills and wood processing plants in Poland. Due to which region of Poland the wood comes from, its technological quality varies (Laurow 1994). In Poland in the 1960s, interest of the qualitative variability of available pine wood and its use in construction and industry was increased. Research work was carried out in various centers, e.g. Paschalis’ studies on the strength of Polish pine wood (Paschalis-Jakubowicz et al. 2015a; Paschalis-Jakubowicz et al. 2015b) and the conventional element method (Oktaba et al. 2002; Mirski et al. 2019). The aim of the study was to compare the properties of timber obtained from three regions of Poland. The comparison is intended to show differences in modulus of elasticity (MOE) depending on the place of origin.
