Nagarjunasagar Srisailam Tiger Reserve (NSTR)

It is the largest tiger reserve in India.
It is spread across 5 districts, some belonging to Telangana state and Andhra Pradesh state.
These forests are also famous for Srisailam temple which is one of the prominent Lord Shiva temples.
The mighty River Krishna which rises in Sahyadri Hills and makes its way through Maharashtra and Karnataka flows across Nallamala tiger reserve.
The tiger reserve mostly has deciduous forests.

The tiger population in NSTR has seen a promising rise in number.
According to the recent tiger census by the Wildlife Institute of India and the National Tiger Conservation Authority (2018), the reserve accounts 74 tigers in total (both AP and Telangana state).
With the limited resources in hand, the forest department, the local tribes, and NGOs have made this possible.
Steps like active surveillance by using sensor-based camera traps and ensuring 24×7 patrolling by the personnel has yielded the rise in tiger population.
