Abstract

The WEST OAK FORESTS have special importance in terms of their positions, functions and diversities. Restoring and developing of these forests depend on qualitative and quantitative characteristics of forest’s stands REGENERATION. In this study, qualitative and quantitative properties of REGENERATION have been studied in a part of west Azerbaijan’s forest (Piranshahr).In this order, 460 ha of perdane’s forest was selected primarily and then 61 circle plots (each one had 100m2) were used in 250×300 m grid. In each plot all annual and perennial seedlings with genus segregation which had diameter less than 7.5 cm at breast height were recorded, as well as, site factors inside plots. According to this study, the mean number of REGENERATION in studied forest stands was estimated 4130 tree per ha which gall oak (Quercus infectoria oliv.) and Lebanon oak (Q. libani oliv.) had highest percentage of mixture among species. The REGENERATION structure was coppice-with-standards. Also between the mean number of seedlings and stem-sprouts REGENERATION of gall oak, Lebanon oak and pear-tree (Pyrus sp.) significant difference was around 95%. But there were no significant differences about azarole (Crataegus sp.) and the other species (a=5%). There were significant difference between mean number per plot of dominant species like gall oak and Lebanon oak (a=5%) in different levels of site factors such as aspects and canopy cover of main stand.
