International Journal of Engineering, Management & Sciences (IJEMS) ISSN-2348 –3733, Volume-3, Issue-9, September 2016 12 www.alliedjournals.com Abstract— In the Thar Desert of Rajasthan due to drought and famine the situations are not favorable for plants and animals. Ziziphus nummularia locally called ―Bordi‖ is a drought resistant plant which can grow in extreme temperatures ranging from 44-52 degree Celsius in the month of June and July and less than 15 degree Celsius in the winter. In drought and famine condition it provides food, fodder and fruit for livestock as well as it is a good source of economy for villagers. It is also useful to stop soil erosion in storm. Necessity of water for Ziziphus nummularia is very low so it could be adapted to grow in drought conditions. Most of the Desert fauna depends on it. Ziziphus nummularia is found in Sacred (Oran) and Pasteur (Gaucher) land. It plays a significant role to support village socioeconomic level and it is drought and famine resistant plant useful for animal as well as human so conservation of this plant most needed because most of the biodiversity in these areas depends on this plant. The plant has great significance in the peculiar desert habitat and its harsh water scarcity. Each part of the plant has its socioeconomic value and its uses in human welfare are so diverse.

Thar Desert spread in about 2 lac square kilometer in the India; out of which more than 60% spread in the Rajasthan. It covers 19.84 million hectares area or 51% of the geographical area of Rajasthan. The Thar Desert resulted in one of a unique diversity and has been maintained and replenished over the centuries by the people themselves (Kaul, 1993; Khoshoo, 1994; Rogers and Panwar, 1988; and Sharma et. all 2013). The concomitant decline in pasture land and fallow lands along with good diversity are also expected to take place (Prakash, 1994). Flora of the region include Acacia senegal (Kumtiya), A. nilotica (Desi Babul), Salvodora persica (Khari Jal), Salvodora oleoides (Mithi Jal), Prosopis cineraria (Khejri), Tecomela undulata (Rohida), Caparis decidua (Ker), Calotropis procera (Aak) and Ziziphus (Ber) species. The entire vegetation are important in this region, but Ziziphus nummularia (locally called “Bordi”) stands greater than other species because of its enormous benefits and uses in the fluctuating Thar Desert ecosystem. G.R. Parihar, Department of Zoology, New Campus, Jai Narain Vyas University Jodhpur, Rajasthan, India Khagendra Kumar, Department of Zoology, New Campus, Jai Narain Vyas University Jodhpur, Rajasthan, India Ziziphus nummularia has numerous benefit it provide fodder, food and fruits. The plant has many economic and household values as dry woods uses for kitchen fuel and various medicinal uses. Most of the avian and mammalian fauna depends on it. Product of this plants are very good source of economy. So the necessary action conservation plan has to be taken in the Thar desert. Study area- The study area included three villages namely Balera, Radva and Juna patrasar, District Barmer, Rajasthan, India with an area of 2692 Square kilometers. The life support systems in this region are compelled by bioclimatic and environmental limitations. Average annual rainfall of the area is 120- 350 mm, extreme pre monsoon temperature ranges between 44 and 52 degree Celsius, high wind speed average annual 10-40 km/hour in summers, high evaporation-transpiration annual 1000-1200 mm. Soils of the Thar generally sandy to loam and rocky with Magra ecosystem (Parihar, 2013) and have a very poor nutrient status. Livestock- Figure -1: Livestock Population.
