The site index conversion equations are important for estimating the site index of one tree species from the site index of another tree species in mixed stands. In this study, data were obtained from 162 sample plots in mixed stands of Scots pine (Pinus sylvestris L.) and Oriental beech (Fagus orientalis Lipsky) from the Black Sea Region in the north of Turkey. The breast height ages and height of the site trees were measured and the site index was estimated by these data. Geometric linear regression was used to estimate the parameters of a linear model relating to site indices …

On 19 May 1998, a small-scale landslide occurred near Hanyeri, Bartın, in the western Black Sea region. The purpose of the study is to investigate the changes in stem growth rates and root wood anatomy of oriental beech (Fagus orientalis Lipsky). According to results from 8 years before and after the event year, growth variation in the affected trees is significantly high. In the control trees, growth increases after the event year, and the growth variation is 116.22%; this value is 69.59% in the affected trees. However, the growth variation values for ±11 years are 107.69% and 81.36% in control …
