Situated in the Nallamalais - an offshoot of Southern Eastern Ghats of A.P., NSTR is decorated with mosaic of Geo-Morphological, floristic and variety of faunal species. Most of this reserve is hilly terrain with plateaus, ridges, gorges and deep Valleys which support tropical mixed dry deciduous forests with an under growth of bamboo and grass. The census taken in 1979 revealed the existence of 40 tigers in this area. Fascinated by the population of Tiger and its suitable habitat, he Govt. of India has brought this sanctuary under the folds of Project Tiger.
