Andhra Pradesh to bring gaurs from central India to feed Nallamala’s tigers
Gaurs have all but disappeared from the reserve and the Nallamala hills; Principal Chief Conservator of Forests P.V. Chalapathi Rao said the translocation would expand the prey base and improve genetic diversity, and that two tigresses each would be brought from Maharashtra and Madhya Pradesh

Context
The Andhra Pradesh government is initiating a translocation project to introduce Indian gaurs from Central India to the (NSTR) and Nallamala forests. This move aims to augment the prey base for tigers and leopards, whose populations are being bolstered by the planned introduction of four female tigers from Maharashtra and Madhya Pradesh. The gaur population in NSTR had previously declined due to hunting, habitat loss, and disease.
UPSC Perspectives
Environmental
This news highlights the critical concept of prey base augmentation in wildlife conservation. For apex predators like tigers to thrive, an adequate density of large ungulates (hoofed mammals) is essential. The decline of gaurs in the created a prey deficit, potentially leading to human-wildlife conflict or population stagnation for the big cats. The translocation of gaurs, facilitated by the , serves a dual purpose: providing sustenance for the carnivores and improving the genetic diversity of the gaur population in the Eastern Ghats. Genetic diversity is crucial for a species' resilience against diseases and environmental changes. Furthermore, the presence of apex predators like tigers acts as an indicator species, reflecting the overall health and balance of the forest ecosystem. UPSC frequently tests the understanding of these ecological interdependencies, such as predator-prey dynamics and the role of keystone or indicator species in maintaining habitat health.
Geographical
From a geographical perspective, the focus is on the (NSTR) and its location within the . NSTR is India's largest tiger reserve by area, spanning multiple districts in Andhra Pradesh and Telangana. The article mentions the , a section of the Eastern Ghats known for its dry deciduous forests, which provide a distinct habitat compared to the denser forests of the Western Ghats or Central India. The article also references , located further north along the Godavari river. Understanding the distribution of species across different geographical regions is a common theme in UPSC Prelims. For instance, knowing that gaurs are currently sparse in the Eastern Ghats but relatively abundant in Central India (where they are being sourced from) is a key geographical detail. Aspirants should map these locations (NSTR, Nallamala hills, Papikonda NP) and understand their respective ecosystems and associated flora and fauna.
Governance
The translocation project underscores the complexities of inter-state coordination in wildlife management. Moving tigers from Maharashtra () and Madhya Pradesh, and gaurs from Central India, requires collaboration between respective State Forest Departments and national bodies like the (NTCA) and the . This reflects a shift towards landscape-level conservation strategies that transcend state boundaries. The article also touches upon the historical reasons for the gaur's decline—hunting, habitat loss, and cattle disease transmission—highlighting the ongoing governance challenges in enforcing the and managing the buffer zones of protected areas where domestic livestock often interact with wild herbivores. UPSC mains questions often explore the effectiveness of such institutional frameworks and the practical challenges of executing complex conservation initiatives like species translocation, assessing both the ecological rationale and the administrative hurdles involved.
