Abstract

Phytosociological studies of grassland communities of Southern Aravalli Hills of Rajasthan are reported in the present communication. It was observed that Heteropogon contortus and Sehima nervosum are more frequent on plain and hillock areas of grassland communities respectively. Heteropogon contortus had the highest density (98.4 individuals/m²) on plain area and Aristida funiculata had the highest density (104.8 individuals/m²) on hillock area. Aristida funiculata was most abundant grass on plain as well as hillock area. Maximum importance value index was shown by Heteropogon contort us and Aristida funiculata on plain and hillock area respectively. The high value (0.047) of dominance index was recorded on hillock area, while low value (0.039) on plain area. Diversity index was found to be negatively correlated (r =-1.00) with dominance index.
