Oriental Beech
grows naturally in the Eastern Caucasus, Northern Iran and Crimea, from the
west of the Balkans towards Anatolia. Akkuş Region of Turkey is one of the
moist ecosystems where this tree species spread optimally. In this spread area,
the change of local site factors affect the site productivity. In this study,
the correlations between the height growth of pure Oriental beech forests
between 1200-1500 m altitudes in Akkuş region and some soil characteristics and
location factors were investigated. 40 sample plots were taken from normally
covered Oriental beech stands. In the sample plots, soil profiles were dug and soil sampling was performed
according to genetic soil horizons. The location factors of the sample plots in
the field were determined, and d0.30 diameter, d0.30 age
and upper height were measured in 4-6 trees with upper stand height. The site
productivity (site index) was determined based on the correlation between
standard age and upper stand height. Physical and chemical soil analyses were
performed in the soil samples taken.
The correlations
between the productivity indexes (site index) of the sample plots and the local ecological characteristics of
the site were tested by correlation analysis. Positive correlations were
determined between site index and the land slope degree and altitude. There are
negative correlations between soil properties of average amount of clay,
average amount of silt, field capacity, fine soil weight, soil reaction, and site
index, while there are positive correlations between horizon Ah's
organic matter, average amount of sand, physiological soil depth, skeleton weight
and site index.
