Current investigation carried out to assess the impact of Prosopis juliflora on habitat condition of blackbuck. The results revealed that Prosopis eradicated area attracted more blackbuck density than the Prosopis invaded area. Density of blackbuck, in different sites viz., site I, site II and site III with the value of direct sighting 0.56 ha^-1, 0.39 ha^-1 and 0.15 ha^-1 respectively and indirect sighting 0.37 ha^-1, 0.22 ha^-1, 0.29 ha^-1 respectively. An effort was also made to study the impact of Prosopis juliflora eradication and effective management for improvement of a blackbuck habitat and indigenous floral species, which shows positive impacts towards high density population of blackbuck in the Sathyamangalam Tiger reserve.
