Site index for mixed stands of scots pine (Pinus sylvestris L.), Uludağ fir (Abies bornmülleriana Mattf.) and beech (Fagus orientalis lipsky) in Zonguldak forest district
Özet
Site index curves and tables have been prepared for uneven aged mixed stands of Scots pine (Pinus sylvestris
L.), Uludag fir (Abies bornmülleriana Matff.) and beech (Fagus orientalis Lipsky.) in Zonguldak territory,
Turkey. Curves and tables have been constructed for every tree species using data from 31 sample plots and 93
stem analyses. Lloyd-Hafley’s method (1977) was used to construct site index curves and tables. Results were
compared with Uludağ fir and beech site index tables prepared for uneven aged pure stands. Results show that
there are differences between uneven aged pure and mixed stands developments, especially at Uludağ fir.
