Popis: Silvicultural operations, including single-tree selection create gaps in forest canopies and these gaps impact on the forests structure. This study examines the influences of different harvest-created gap sizes on the oriental beech (Fagus orientalis L.) trees traits in temperate Hyrcanian forest, northern Iran. We selected three gap sizes (small, medium and large) and the adjacent unlogged closed canopies with five replications for each and measured some features of beech trees in overstory at the gaps-edge and closed stands. The results showed that gap size significantly influenced on crown length, crown surface area, crown ratio, bole, height/diameter (H/D) and minimum radius / maximum radius (CA) ratios of beech trees six years following gap creation (P
