This study was conducted in the pasture and range areas of Van and near vicinity. During the vegetation studies, 5 plant associations were determined. In the regions with higher ground water level trifolio-Hordeetum murini, Medicago-Hordeetum bulbusi and Hordeo-Poetum trivialii associations: in the bog areas Typho-Phragmitetum austrialii association were observed. On the other hand, an Eryngio-Astragaletum microcephali association was determined in the steppe areas. The most important factors and different plant associations and their widespread sn pastures were found to be the ground water level, the content of CaCO3, organis matter and saltness; while in range areas the thopographic factors such as altitute, direction and inclination of slopes, and utilization type were effective
