In a major conservation move, the Andhra Pradesh government plans to reintroduce Gaurs from central India to the Nagarjunasagar-Srisailam Tiger Reserve to replenish the dwindling prey base for tigers.

Key Takeaways

  • Gaurs will be translocated from central India to NSTR and Nallamala forests starting September.
  • Four female tigers from Maharashtra and Madhya Pradesh will also be relocated to the reserve.
  • The move aims to restore the prey base and enhance genetic diversity.
  • The project is being executed with support from the Wildlife Institute of India.

The Andhra Pradesh government has initiated critical steps to bolster the population of Gaurs (Indian Bison) within the Nagarjunasagar-Srisailam Tiger Reserve (NSTR) and the Nallamala forests. This strategic move is designed to expand the prey base for apex predators like tigers and leopards, which have faced food shortages due to the disappearance of large herbivores.

Principal Chief Conservator of Forests (PCCF) P.V. Chalapathi Rao noted that Gaurs have almost vanished from the NSTR and Nallamala hills over recent years. This decline was primarily driven by illegal hunting, habitat fragmentation, and the transmission of diseases from domestic cattle. To rectify this, the Forest Department, in collaboration with the Wildlife Institute of India, will begin translocating Gaurs from central India this September.

Why This Matters

BozokMedia analysis shows that the stability of a tiger reserve is directly proportional to the density of its herbivore population. Without large-bodied prey like the Gaur, tiger populations face reproductive stress and increased conflict with human settlements. By reintroducing these massive bovines, the state is essentially rebuilding the foundation of the Eastern Ghats' food web.

Tigers, as apex predators, serve as the ultimate indicator of the overall health of wildlife habitats.

Furthermore, the state is preparing for the translocation of four female tigers—two each from Chandrapur in Maharashtra and from Madhya Pradesh. These big cats will be released into the NSTR, which spans an impressive 5,443 sq km. Current estimates suggest the NSTR-Seshachalam region hosts approximately 68 tigers and 11 cubs.

Historical Background

Historically, the Nallamala forest range was a stronghold for diverse megafauna. However, the encroachment of grazing cattle and the loss of contiguous forest corridors led to a catastrophic decline in the natural prey populations, necessitating this high-stakes biological intervention.
