Owing to the importance and necessity of identifying soil properties in arid rangeland management, and the variable
effects of different kinds of herbivores on soil, this study compares some of the physical and chemical properties of
soil between two regions experiencing livestock and wildlife grazing in the desert rangelands of Kalmand-Bahadoran
in Yazd province. The key areas in two regions experiencing livestock and wildlife grazing were selected, and soil
samples were taken at depths of 0-30 cm using the systematic random sampling method. All samples were then
transferred to the laboratory to determine the desired parameters. Finally, soil characteristics were compared between
the two regions. The results indicate that physical properties of the soil such as clay and moisture percentage show no
significant differences. Bulk density in the region of livestock grazing reveals a highly significant increase compared
to the area under wildlife grazing (P<0.01). Calcium carbonate, acidity and electrical conductivity parameters also
saw a significant increase from 18.33%, 8.47% and 1.46% in the region with livestock grazing to 14.91%, 8.36% and
1.35% on the wildlife grazing site respectively (P<0.01). In terms of organic matters there was no significant
difference between the two study sites. Overall, changes in soil properties have occurred as a result of wildlife
grazing from halophyte and shrub species and from less grazing pressure at the site.
