Knowledge of the spatial patterns of plants distribution is necessary for  the measurement and investigation of vegetation. This research was carried out to study and analysis the distribution pattern of Berberi integerrima in Asbchar rangelands of Baladeh Mountains at the Noor County. Sampling method was random- systematic along three transects with 100 meters length within the type of 1400 hectare. 10 random points were selected along each transect with distance of 10 m and were performed measurements. After choosing any random point, were measured its distance to the nearest plant, distance of that plant to nearest neighbor plant and distance of random point to second nearest plant. Using this data was calculated distance indices of distribution (Eberhart, Hopkins, Holgate, Johnson and Zimmer). In addition, in each random point were established 3m² plots and were counted number of plants at them. With this information were calculated the quadratic indices of distribution (variance mean, green, Lloyd, Morisita and standard Morisita). The results of methods of one hundred percent sampling methdos such as nearest neighbor, K Rieply and Ld showed that distribution pattern of the species is clumped. Between the distance indices of distribution, Johnson and Zimmer, Eberhart and Hopkins with values 2.66, 2.05 and 0.6 respectively and between the quadratic indices, variance mean, green, Morisita and standard Morisita with values 6.88, 0.2, 2.3 and 0.53 respectively showed clumped pattern for this species. Therefore, for determination of the distribution pattern of this species must be used these methods and pay attention to are better methods to clumped pattern of this species when rangeland are reclaiming with this species.
