摘要：The success of natural regeneration using the Uniform Shelterwood Method (USM) was
determined in an oriental beech (Fagus orientalis Lipsky.) stand, in the Bartın-Sökü Forest Range
District. Number, height growth and root collar diameter of seedlings were investigated in the
10 experimental plots in the 5.0 ha regeneration area for 7 years (2004–2010). According to the result
of factor analyses, it was found that amount of filled seeds, soil cover, growth status of seed trees,
stand canopy closure, average crown projection area of seed trees, amount of organic substance in the
upper soil layer, soil reaction in the upper soil layer and hillside status were the most effective factors
determining the success of natural regeneration.
