VARIATION IN MECHANICAL PROPERTIES OF BEECH (FAGUS ORIENTALIS LIPSKY) WOOD GROWN AT DIFFERENT ELEVATION OF ASALEM FORESTS (GILAN), IRAN

In this study physical and mechanical properties of Beech (Fagus orientalis Lipsky) grown at two different elevations of Asalem Forests located an the north west of Gilan were investigated following the ASTM Standard. Sample trees were selected from 2 different elevations, at different high of trees, at 4 different geographical directions of the stems and 2 different moisture contents. The results of statistical analysis revealed that properties of Beech wood from this region was influenced by elevations and to the lessees extend to geographical direction of wood specimens and tree highs.
