Abstract

This research was conducted to study the effect of implementation forest protected plan on quantitative and qualitative characteristics, extension of Loranthus europaeus and regeneration in Salas-babajani’s Forest stands. For this purpose, in the protected and unprotected region, 40 hectares area with similar physiography and floristic condition in a range of 1250 to 1550 meters above sea level, were selected. 40 circular sample plots with 1200 m2 area in a 100*100-meter inventory grid was established in each of them. In each sample plot, the general specification of the location of the sample plot such as slope, altitude, aspect, species type, quantitative characteristics of tree (diameter at breast height, small and large diameter of the crown) measured. Independent t-test and chi-square test were used to compare quantitative and qualitative data, respectively. According to the results of this study, Quercus brantii and Crataegus sp. had the highest and lowest percentage of mixing in the forest stands of the study area, respectively. The mean of crown diameter, the percentage of healthy trees, average sprout number and the average number of Loranthus europaeus in the polluted trees in protected area were higher than unprotected area. The results of this research indicated that the forest conservation-based management has positive effect on quantitative and qualitative characteristics in protected forests and emphasized the necessity of conservation, regeneration and development of these forests.
