Abstract

In this study, GRAZING GRADIENT method (systematic changes in vegetation cover with distance from stock watering points and villages) has been used to determine the characteristics of SOIL AND VEGETATION of RANGELANDs. For measuring ground based data, 200 M transects and 3 M2 quadrats have been used. Factors such as vegetation cover, litter, plant diversity, bare soil, stone and gravels were evaluated in ground-based data collection. It should be noted that, ground based data measurement was conducted around stock watering points and villages as two important CRITICAL POINTS on RANGELANDs. The results of ground based data analysis reveal that there was a significant correlation between distance from CRITICAL POINTS and plant diversity (r=0.97, p<0.01), and litter percent (r=0/96, p<0.01). Litter and plant diversity increase by distance from CRITICAL POINTS. Vegetation cover has a significant correlation with distance from rural villages (r=0.95, p<0.01) while it was not the same around watering points. It means that there was not significant correlation between vegetation cover percent by distance from watering points (r=0.63, p>0.05). Correlation between bare soil and distance from CRITICAL POINTS was the same to vegetation cover changes manner. There was high significant correlation between them around villages (r=097, p<0.01) and low correlation around watering points (r=0.99, p<0.01). About stone and gravel cover percent, however, there was not significant correlation by distance from CRITICAL POINTS and their cover percent (r=0/47, p>0.05).
