Abstract

The current study was carried to find DISTRIBUTION PATTERN of Zygophyllum eurypterum Ephedra strobilceae , Haloxylon aphyllum and Cornulaca monocantha in Poshtkouh rangelands in Yazd province using distance and QUADRAT INDICES. To do this, in a 20 ha area, 4 transects with a length of 400 m were established based on random-systematic method. Vegetation sampling was performed along each of transects .in 30 points. In each point, its distance to nearest plant, distance between mentioned plant and its nearest neighbor, and distance between the point and second plant was measured. Using these measurements, DISTANCE INDICES including; Eberhart, Hopkins and Holgate were calculated. To use QUADRAT INDICES, in each of abovementioned 30 points, quadrats with different sizes (according to plant kinds) were established and number of plants within quadrats were counted. Regarding obtained data from quadrats, indices of variance/mean, Morisita and standard Morisita indices were calculated. Results showed that Z. eurypterum, H aphyllum and C. monocantha DISTRIBUTION PATTERN was random, while E. strobilceae DISTRIBUTION PATTERN follows a clumped pattern. Also, it was cleared that the accuracy of distance methods was higher than quadrat methods and resulted to more reliable results in determination of plants DISTRIBUTION PATTERN.
