Aim: In this paper, the semi–circular bund treatments were contrasted to address the following questions: how does semi-circular bund affect the vascular plants richness and diversity in Naroon and Neron rangelands of Sistan and Baloochestan? and do the soil properties responses to the semi–circular bund?
Materials & Methods: Next to every site, a site was selected as controlled ones. Vegetation (production, vegetation cover, density, richness, diversity) and soil data (texture, pH, EC, organic carbon, total nitrogen, available phosphorus, available potassium, CaCO
3) were analyzed in completely randomized design.
Findings: In total, 11 species from 6 families and 8 genera were observed. Control treatment of Neron exhibited the highest number of plant species. Semi-circular bunds exhibited the highest vegetation cover, production and density. The highest and lowest species richness and diversity were measured in Naroon and Neron semi-circular bunds. Results showed that the amounts of organic carbon, nitrogen, potassium and phosphorus increased significantly in semi-circular bunds compared with the control areas. The highest organic carbon, nitrogen and potassium related to Neron semi-circular bund. Naroon and Neron semi-circular bunds had the highest amounts of clay and the least value was measured in the control treatments.
Conclusion: In total, the results of study showed that semi-circular bund had positive effect on vegetation cover and soil properties in the rangelands of study area.
