Silvicultural Assessment of Regeneration Areas of Oriental Spruce (Picea orientalis (L.) Link.) in Giresun- ？kisu Forest District

This study was carried out to examine natural regeneration of Oriental spruce (Picea orientalis (L.) Link.) which was an important commercial and social-cultural forest tree species to contribute silvicultural practices of the species in Giresun-Ikisu forest district. For the purpose, four natural regeneration area regenerated between 2011 and 2015 were sampled, and also three replicates 100 m2(5x20m) from each area. Height, diameter and age of seedlings were measured in each replicates. Beside, seedlings were counted by 2m2 square to estimate regeneration success. Significant differences (p≤0.05) were found among seedlings of Picea orientalis, Abies nordmanniana and Fagus orientalis for diameter, height, and age according to results of analysis of variance. There was significant phenotypic correlations (p≤ 0.05, r>0.54) among the characters based on results of correlation. Natural regeneration was successful (> 85 %) based on number of counted seedlings
