Study on The Structure of Juniperus excelsa Beib. Stand in Khakhal Protected Forests

Structure study of the forest is one of the important subjects of silviculture close to nature. Recognition of Juniper forests as the main structure of natural forest ecosystems, is necessary for the degradation process. In this research, in order to study the structure of natural Juniper stand in protected forest, 49.53 ha of Juniper stand was selected (Khalkhal forests) and 100% inventory was applied. Forest stand characteristics including species mixture, number per hectare, diameter at breast height, total height and crown diameter were measured and analyzed. Results show that the stand is basically uneven-aged and Juniperus excelsa is the dominant species. The mean forest canopy, mean basal area and mean number per hectare are 42.85%, 4.68 m² and 592, respectively. The stem number frequency of tree in diameter at breast height shows an uneven-aged pattern. Totally, the study of stand in terms of structural is a mixed, unevenaged and open canopy cover stand.
