Quick Revision: The inquiry into tiger deaths in the NSTR underscores the urgent need for robust habitat management, enhanced patrolling, and community-based conservation to mitigate human-wildlife conflict and ensure the long-term survival of India’s tiger populations.

Why is this in the news?

The Andhra Pradesh government has constituted a high-level inquiry committee, led by retired IFS officer P. Mallikharjuna Rao, to investigate the recent spate of tiger deaths in the Nagarjunasagar Srisailam Tiger Reserve (NSTR). Within a span of less than three weeks in July 2026, three tiger carcasses were recovered from deep forest areas, raising serious concerns about wildlife protection mechanisms, habitat integrity, and systemic conservation failures in one of India’s premier tiger reserves.

Background

• The Nagarjunasagar Srisailam Tiger Reserve (NSTR), spread across Andhra Pradesh and Telangana, is one of the largest tiger reserves in India, notified under Project Tiger in 1983.
• The reserve spans five districts: Kurnool, Prakasam, Guntur, Nandyal, and Mahabubnagar, and serves as a critical habitat for Bengal tigers, leopards, and a rich diversity of flora and fauna.
• The NSTR is part of the Eastern Ghats landscape and is ecologically significant due to its contiguous forest cover, which supports viable tiger populations and acts as a wildlife corridor connecting the Eastern and Western Ghats.
• The reserve has faced recurring challenges such as habitat fragmentation, illegal encroachments, mining activities, and escalating human-wildlife conflict due to expanding agricultural and infrastructural development.
• The National Tiger Conservation Authority (NTCA), established under the Wildlife (Protection) Act, 1972, monitors tiger populations and enforces conservation protocols across tiger reserves in India.
• In 2026, four tiger deaths have been officially recorded in Andhra Pradesh, all within the NSTR, indicating a potential systemic issue requiring urgent intervention.

What is the Nagarjunasagar Srisailam Tiger Reserve (NSTR)?

• NSTR is a notified tiger reserve under Project Tiger, established to ensure the conservation of the Bengal tiger (Panthera tigris tigris) and its habitat in the Eastern Ghats.
• It is the largest tiger reserve in India by area, covering approximately 3,568 square kilometers.
• The NSTR plays a crucial role in maintaining ecological connectivity between the Eastern and Western Ghats, facilitating gene flow and species migration.
• The reserve is divided into core and buffer zones, with the core area designated as inviolate for wildlife, while the buffer zone allows for limited human activities under strict regulatory oversight.
• The NSTR faces significant anthropogenic pressures, including illegal mining, encroachment for agriculture, and infrastructure projects such as roads and dams, which fragment habitats and increase human-wildlife conflict.
• The reserve is also a site for eco-tourism, which, while economically beneficial, must be managed sustainably to avoid stressing wildlife populations.
• The recent tiger deaths have highlighted systemic gaps in anti-poaching patrols, scientific monitoring, and habitat management within the reserve.

Key Features

Why it Matters

Ecological Significance

• The Nagarjunasagar Srisailam Tiger Reserve (NSTR) is a critical habitat for tigers and other keystone species, forming part of the Eastern Ghats landscape, which is vital for biodiversity conservation in peninsular India.
• Tiger mortality in core habitats like NSTR can disrupt ecological balance, leading to cascading effects on prey populations and forest regeneration.
• The reserve is part of the larger Central Indian Tiger Landscape, which is crucial for maintaining genetic connectivity among tiger populations across India.

Administrative Significance

• The constitution of a high-level committee under a retired IFS officer reflects the State’s commitment to addressing wildlife conservation challenges with urgency and technical rigor.
• The 72-hour report deadline and two-month conservation recommendations underscore the government’s prioritization of wildlife protection as a policy objective.
• The inclusion of international conservation bodies (e.g., WWF-India) and technical experts highlights the integration of global best practices in local conservation efforts.

Policy Relevance for UPSC

• This incident aligns with the broader theme of ‘Environmental Conservation and Biodiversity’ in the UPSC syllabus, particularly under the sub-topics of ‘Project Tiger’ and ‘Wildlife Protection Act, 1972’.
• The inquiry process exemplifies the implementation of the ‘National Tiger Conservation Authority (NTCA) Guidelines’ for tiger reserve management and mortality investigations.
• The case study can be used to illustrate challenges in ‘Wildlife Crime Control’ and ‘Human-Wildlife Conflict Mitigation’ under the Environment and Ecology section.

Challenges

1. Habitat Fragmentation and Degradation

• The NSTR faces pressure from anthropogenic activities such as mining, irrigation projects, and agricultural expansion, which fragment tiger habitats and reduce prey availability.
• Degradation of forest corridors due to developmental projects (e.g., dams, roads) isolates tiger populations, increasing vulnerability to inbreeding and disease.
• Climate change-induced shifts in vegetation patterns may further reduce the carrying capacity of the reserve for tigers and prey species.

2. Poaching and Illegal Wildlife Trade

• Despite legal protections, poaching for body parts (e.g., skin, bones) remains a persistent threat to tiger populations in India, including in Andhra Pradesh.
• The remote and dense terrain of NSTR poses challenges for patrolling, making it susceptible to clandestine activities by poachers.
• The recent deaths could be linked to poaching, as forensic investigations often reveal traces of poison or snares in such cases.

3. Human-Wildlife Conflict

• Expansion of human settlements into forest fringes increases encounters between tigers and local communities, leading to retaliatory killings or accidental deaths.
• Livestock grazing within the reserve depletes prey populations, forcing tigers to venture closer to human habitation in search of food.
• Poor implementation of compensation schemes for livestock losses exacerbates conflicts, as seen in several tiger range states.

4. Disease Outbreaks and Genetic Isolation

• Tigers in isolated populations like NSTR are vulnerable to epizootics (e.g., canine distemper, feline panleukopenia) due to limited genetic diversity and lack of veterinary interventions.
• Inbreeding depression in small, isolated populations can lead to reduced fitness and increased susceptibility to diseases, as observed in other tiger reserves.

Mains Practice Question

✍ The recent spate of tiger deaths in the Nagarjunasagar Srisailam Tiger Reserve (NSTR) has raised concerns about the efficacy of wildlife governance in India. Critically examine the institutional and ecological challenges in tiger conservation, with particular reference to the role of the National Tiger Conservation Authority (NTCA) and State forest departments. Also, suggest measures to strengthen tiger conservation efforts in the context of the recent committee constituted by the Andhra Pradesh government. (15 Marks)

Approach: MODEL-ANSWER SKELETON:
1. **Institutional Challenges**:
– Role of NTCA: Statutory body under the Wildlife Protection Act, 1972; functions include monitoring tiger populations, approving Tiger Reserves, and guiding State governments. Critique: Limited enforcement powers, reliance on State governments for implementation, and delays in decision-making.
– State Forest Departments: Fragmented governance, inadequate funding, and human-wildlife conflict management issues. Example: NSTR falls under Andhra Pradesh, which has faced criticism for poor forest governance.
– Recent Committee: High-level committee constituted by Andhra Pradesh under retired IFS officer P. Mallikharjuna Rao to investigate tiger deaths and recommend long-term measures. Highlight its composition (WWF-India, wildlife conservationists) and terms of reference (anti-poaching, community participation, eco-tourism).

2. **Ecological Challenges**:
– Habitat fragmentation and loss of wildlife corridors in NSTR due to anthropogenic pressures (e.g., infrastructure projects, agriculture).
– Human-wildlife conflict: Increasing encroachment into tiger habitats leading to retaliatory killings.
– Climate change impacts: Droughts and forest fires exacerbating habitat degradation.

3. **Measures to Strengthen Conservation**:
– Strengthening NTCA: Empower it with greater enforcement powers, including the ability to penalise States for non-compliance with conservation guidelines.
– State-level reforms: Enhance funding for forest departments, improve patrolling systems, and adopt technology (drones, camera traps) for monitoring.
– Community participation: Involve local communities in conservation efforts through eco-development initiatives and compensation mechanisms for human-wildlife conflict.
– Scientific monitoring: Expand the use of camera traps, GPS collaring, and genetic studies to track tiger populations and health.
– Mitigating human-wildlife conflict: Implement early warning systems, promote sustainable land-use planning, and establish dedicated wildlife corridors.

4. **Conclusion**: Balancing conservation with developmental pressures requires a multi-stakeholder approach, with NTCA playing a more proactive role and States adopting adaptive management strategies.
