The present paper deals with phytosociological study in the sandy plains of the Thar Desert of Rajasthan. Panchpadra, Balotra and Nakoda of Barmer district of Rajasthan represent some unique semi-arid and arid vegetation characteristic. Barmer lies in the southern part of North-west Rajasthan. Barmer district is situated at 710 35’ 49.59" E longitude and 260 13’ 51.48" N latitude. The entire region of Barmer district is hot and sandy. Generally the vegetation in this arid region is sparse. Mainly xerophytic adapted plants are able to establish themselves in this region. The IVI value of tree species varied from 10.30 to 24.32. Variations are observed in vegetation characteristics in the three sites studied. Contagious and random distribution is recorded at all the sites but regular distribution is found only in Balotra area. The study may be used for restoration of natural vegetation in such a desert ecosystem.
