Site description Rajiv Gandhi Wildlife Sanctuary, formerly known as Nagarjunasagar-Srisailam Tiger Reserve spreads over five districts Nalgonda, Mahboobnagar, Kurnool, Prakasam and Guntur in Andhra Pradesh. The landscape is hilly and varies from plains to precipitous cliffs. The wildlife is generally confined to the plateaus during the monsoon and to the valleys in the summer. Perennial water sources are located in the valley, while the plateaus suffer from acute water scarcity in the summer. The River Krishna flows over a distance of 130 km through the Reserve. The multipurpose reservoirs, Srisailam and Nagarjunasagar, which are an important source of irrigation and power for Andhra Pradesh, are located within the Tiger Reserve. The area receives rainfall from both the southwest and northeast monsoons. The vegetation is essentially Southern Tropical Mixed Forests (Champion and Seth 1968). Important tree species are Tectona grandis, Terminalia tomentosa, Anogeissus latifolia, Butea frondosa, Pterocarpus marsupium, Hardwickia binata. In the scrub patches, Acacia arabica, Madhuca indica and Hardwickia binata stand over Calotropis gigantea, Zizyphus oenoplia, Grewia spp. and Cassia auriculata. Occasional clumps of bamboo are encountered on the hillsides and on the banks of forest streams. The invasive Lantana, Parthenium, Duranta and Strobilanthus grow profusely as weeds in this area (Rao et al. 1997).
