Abstract:
Plant communities are constantly declined due to various biotic and abiotic factor such as drought, highs alinity, temperature, overgrazing and urbanization. It imposed a threats of extinction to the native plants species so there was need to protect these economically and naturally important plants. Protected are as conserves a threatened or endangered species habitat, species diversity, and population dynamics of range facing harsh condition.The cholistan desert has a very limited and subnormal vegetation cover so it was, thus imperative that necessary steps should be taken not only to restore it to its original level but also to improve it.The present study was conducted to analyze the effect of different fencing regimes on a community structure of perennial plant species in Cholistan desert. Major sites include Derawar Fort (Biodiversity Park IUB), Mauj Garh Fort (Livestock Farm) And Lal Suhanra National Park (Sheikh Mohammed Bin Zayed Al-Nahyan Conservation and Breeding Center). In each site, thirty-three quadrates measuring10x10m2 are laid out at random.e.g. eleven quadrate at each subsites (sanddune, interdune and clayeyland). During the study the parameter which we covered are density, relative density, relative frequency, cover, relative cover, importance value index and diversity index. After the completion of the study 31 families and 57 species are reported in all three sites. Generally, Ochthochloa compressa, Suaeda fruticose and Lasiurussc indicus showed very high values of relative density, relative frequency, relative cover and importance value. Cenchrus ciliaris, Cymbopogon jwarancusa followed by Haloxylon salicarnicum have moderate while Ziziphus nummularia, Salvadora oleiodes, Aristida hystricula, Calotropis procera and Heliotropium crispum have very low values of phytosociology parameters. The average of Diversity index of all species are found at all three siteswas (0.8009822). Over all selected three sites play an important role in the conservation of many native species of desert that are otherwise facing multiple biotic abiotic and anthropogenic factors.
