Spatial pattern in oriental beech (fagus orientalis lipsky.) and uludağ fir (abies nordmanniana ssp. bornmuelleriana mattf.) mixed forests

Both of two sample plots have been chosen within the mixed forests of Hasankadı Forest Sub-District Directorate for analysis of natural regeneration of Oriental beech (Fagus orientalis Lipsky.) and Uludağ fir (Abies nordmanniana ssp. bornmuelleriana). The locations of all saplings (height ≤ 0.8 m), seedlings (height > 0.8 m) and trees (height > 1.8 m) have been determined, and the measurements have been performed. Spatial pattern analysis and statistical assessments have been carried out by Ripley’s K function in R software. Although grouping has been observed in all growth stages of Uludağ fir and oriental beech, there is a positive relationship between juvenilities of fir and older beech trees. These results indicate the stable growth in first stages of development. It is understood that the suitable growth locations are under the canopy of beeches for abies and under the older beeches for beech trees.
