| Abstract | ||
| The study on gender ratio and forest stand characteristics is the most important issue in forest ecology. With respect to forest degradation in natural stands of juniper, as one of the most important forest ecosystems, the study on their characteristics is essential. In the current research, some characteristics and gender ratio of juniper stands in the Layzangan site of Fars province were studied. One of the best sites was selected and then 12 circular plots with 1000 m2 area according to a cluster design were set in both the northern and southern slopes of the study habitat. Some characteristics such as the type of species, collar diameter, height, canopy area, and gender ratio were recorded at all plots. The result indicated that the number of trees per hectare in northern slope was 85 tree individuals, while it was 58 for the southern slope, and the basal area per hectare varied between 1 to 3.4 m2. Not only the male to female ratio of both slopes had a deviation from the 1:1 ratio, but the ratio for the both slopes was different from each other. | ||
