Abstract As part of global experiments on Savanna vegetation, we examined the ecological characteristics of an important
semiarid savanna in the Indian sub-continent i.e Sariska Tiger Reserve, Rajasthan, Western India during April 2009 to
May 2011. 149 plots across five line transects were sampled for phyto-sociological interpretation in the Sariska-Kalighati
valley which is the largest savanna valley habitat in the study area. Plots were segregated on the presence/absence of
native invasive species Adhatoda vasica and community analysis revealed a total of eleven communities (five from
infested plots and six from non-infested plots) and communities having similar composition were compared. Tree
density, seedling density, species richness of shrubs and herbs and diversity and evenness of herbs was higher in noninfested
plots. Sapling density did not follow a trend. Evenness of shrubs was lower in non-infested plots. Furthermore,
2 mapping of Adhatoda vasica in the study area revealed that 5.22 km (26.1%) of the Sariska-Kalighati valley was under
infestation and three sites were compared following removal of this species which resulted in increased sapling density,
shrub density and grass cover and decreased seedling density and herb density.
