Abstract

Spatial patterns of vegetation in a range type dominated by Bromus tomentellus and Astragalus verusin Feridan- Isfahan were studied. Four 50 m2 reference sites were randomly selected (5 by 10 m). All perennial species were counted and their coordination was recorded accordingly. Two approaches were used to measure average distance between plants including “Closest individual” and “Nearest-neighbor method”. Individual plants were counted in quadrates. Spatial patterns of vegetations were determined using three methods including, POINT PATTERN Analysis, Spatial Indices (Hopkines, Pielou, Johnson and Zimer Index) and Quadrate Indices (Green and Morisita Index).Results indicated that perennial species had randomized spatial patterns due to the relatively homogeneous environmental characteristics of studied area and also selective pattern of vegetation.Point pattern analysis had more accuracy because it considered all perennial species coordination.With sufficient sample size and appropriate quadrate size and shape, quadrate indices had acceptable accuracy. Hopkines index had more precision to determine spatial pattern of vegetation than Johnson, Zimer and Pielou indices. It indicated that spatial indices based on the plant to plant distance (Nearest-neighbor method) had more precision than indices that derived from point to plant distance (Closest individual).
