Botanical Composition and Species Diversity of Arid and Desert Rangelands in Tataouine, Tunisia

چکیده
Natural rangelands occupy about 5.5 million hectares of Tunisia’s landmass, and 38% this area is in Tataouine governorate. Although efforts towards natural restoration are increasing rapidly as a result projects, the degraded has continued to expand severity desertification intensify. Any damage caused by disturbances, such grazing recurrent drought, may be masked return favorable rainfall conditions. In work, conducted during March 2018, we surveyed botanical composition species diversity southern Tunisia. The flora comprised 279 belonging 58 families, with 54% annuals 46% perennials. Asteraceae family had greatest richness species, followed Poaceae, Fabaceae, Amaranthaceae, Brassicaceae, Boraginaceae, Caryophyllaceae, Lamiaceae, Apiaceae, Cistaceae. Therophytes made highest contribution, chamaephytes hemicryptophytes. Of all these 40% were palatable highly more than 13% used both traditional modern medicine.

In arid and semi-arid rangelands, grazing as one of the natural or human induced processes has direct and indirect effects on structure and dynamics of plant community and ecosystems. A study was done to analyze the effects of grazing on plant species diversity and Plant Functional Types‘ (PFTs) diversity of arid and semi-arid rangelands. We analyzed plant richness and diversity data from 75 sa...
