The Spatial Pattern Analyses of Natural Pure Oriental Beech (Fagus orientalis Lipsky.) Stands in the Bartin-Yenihan District in Turkey

Abstract

In this study, was carried out in the pure oriental beech (Fagus orientalis Lipsky) stand of 70a division in the Bartın-Yenihan district,
based on Ripley's L(r) function, the spatial distribution of beech trees in natural stands indicated an aggregate pattern, because the index of
pattern L(r) was more than zero (L(r)=0.88). In order to test the null hypothesis of spatial randomness, we computed a 95% confidence
interval of (r) indicated that clumped pattern was acceptable (H= 2.96, the critical lower limit of the Hopkins test for aggregated pattern =
1.55). Also, based on T-Square method, results showed that the spatial pattern is clumped (Table 1). Hopkins test result with a confidence
95% indicated that the null hypothesis was unacceptable (H = 2.96, the critical lower limit of the Hopkins test for aggregated pattern =1.55).
