Great Indian Bustard Rewilding 2026: Two Captive-Bred Birds Released into Desert National Park — A Conservation Milestone After 10 Years

Why in News

On October 3–4, 2026, Union Minister for Environment, Forest and Climate Change Bhupender Yadav inaugurated the formal process of releasing two captive-bred male Great Indian Bustards (GIB) into the wild at Desert National Park (DNP), Jaisalmer, Rajasthan. Rajasthan Chief Minister Bhajan Lal Sharma participated via video conference. This marks the first-ever rewilding of captive-bred GIBs in India — a milestone achieved after ten years of sustained effort by the Wildlife Institute of India (WII) under the Ministry of Environment, Forest and Climate Change (MoEFCC).

Background

The Great Indian Bustard (Ardeotis nigriceps) is one of the heaviest flying birds in the world and India's most endangered large avifauna. Once distributed across 11 Indian states, its range has contracted to isolated fragments in Rajasthan, Gujarat, Maharashtra, Karnataka, and Andhra Pradesh. The population has declined catastrophically from approximately 1,000 individuals in 1969 to just 130 ± 21 birds as per the latest Wildlife Institute of India survey (2017–2025).

Reasons for Decline

• Powerline collisions: GIBs have poor forward vision and cannot detect high-voltage transmission lines, making electrocution the single largest proximate cause of mortality in recent decades.
• Habitat loss: Conversion of dry grasslands (the GIB's primary habitat) to agriculture, solar parks, and wind farms. Between 2017 and 2025, solar plant coverage in GIB habitat increased by 45% and power-line density increased by 38.1%.
• Hunting and predation: Historical poaching (now controlled) and increased feral/stray dog and fox predation in fragmented habitats.
• Low reproductive rate: GIBs lay only one egg per year, making natural population recovery extremely slow.

Timeline

Current Developments

Two captive-bred adult male GIBs were soft-released into a large, predator-free grassland enclosure within Desert National Park on October 4, 2026. The release was described as a pilot/soft release, not a full reintroduction: the birds enter a 200 sq km fenced, predator-free grassland where they will acclimatize to natural conditions before any final unconfined release is considered.

The newly inaugurated Rewilding Aviary at Ramdevra (approximately 160 km from Sam) served as the final pre-release conditioning facility. The aviary's dimensions — 160 m × 64 m × 14 m, pillar-less — allow birds full, unobstructed flight capability and exposure to natural weather, enabling muscle development and reduction of human imprinting. The aviary was constructed by the Rajasthan State Road Development and Construction Corporation at a cost of Rs. 9.25 crore.

Constitutional Provisions

Article 48A (Directive Principles of State Policy): Directs the State to protect and improve the environment and safeguard forests and wildlife. Article 51A(g) (Fundamental Duties): Imposes a duty on every citizen to protect and improve the natural environment including forests, lakes, rivers, and wildlife and to have compassion for living creatures. Both form the constitutional basis for India's wildlife protection legislation.

Legal Framework

Wild Life (Protection) Act, 1972 — GIB is listed under Schedule I, which provides the highest level of legal protection; killing, capturing, or trading in GIBs carries the most stringent penalties. GIB is also listed under Appendix I of CITES (Convention on International Trade in Endangered Species) and CMS (Convention on Migratory Species), prohibiting commercial international trade.

The conservation actions are governed by the Supreme Court judgment in M.K. Ranjitsinh & Ors. v. Union of India — WP(C) No. 838 of 2019. Key orders:

• April 2021: Blanket ban on overhead power lines over ~99,000 sq km; mandatory bird diverters on existing lines.
• March 2024: Blanket ban modified; targeted undergrounding of power lines in highest-risk zones.
• December 2025: 80 km undergrounding in Rajasthan, 79 km in Gujarat; CSR declared a constitutional duty for species protection; ban on new wind/solar projects over 2 MW in priority GIB areas.

Institutional Framework

• Ministry of Environment, Forest and Climate Change (MoEFCC) — nodal ministry for the programme
• Wildlife Institute of India (WII), Dehradun — scientific lead for captive breeding, population monitoring, and rewilding
• Rajasthan Forest Department — field implementation, habitat management, predator-free enclosure management
• Supreme Court Expert Committee — mandated by SC to guide GIB conservation actions
• IUCN SSC Bustard Specialist Group — international scientific advisory body
• IFHC (Abu Dhabi) — international knowledge-partner for captive management of bustard species

Environmental Dimensions

The GIB is a flagship species for India's dry grassland biome — an ecosystem recognised by IUCN as one of the most threatened on earth, yet underrepresented in India's protected-area network. The species acts as an umbrella for dozens of other grassland-dependent species including the Lesser Florican and the Indian Wolf. Restoring GIB populations therefore signals broader grassland health.

The rewilding initiative also aligns with India's obligations under the Kunming-Montreal Global Biodiversity Framework (GBF, 2022), specifically Target 4 (halt species extinction, prevent species decline) and Target 3 (30×30 — protect 30% of land and oceans by 2030). India submitted its National Biodiversity Strategy and Action Plan (NBSAP) update in 2024 citing GIB conservation as a flagship commitment.

Challenges

• Powerline density rising faster than undergrounding: Solar and wind energy expansion continues to increase transmission infrastructure in GIB habitat faster than court-mandated undergrounding progresses.
• Low reproductive rate: Even under ideal conditions, GIBs cannot rapidly replenish losses — population recovery will span decades.
• Captive adaptation: Reintroduced birds must learn anti-predator behaviour not acquired in captivity; the 3–6 month rewilding-aviary phase addresses this only partially.
• Habitat fragmentation: Isolated wild populations in Gujarat and Karnataka have no genetic linkage with the Rajasthan core, raising long-term inbreeding risks.
• Human-wildlife conflict: Local communities' agricultural and pastoral interests in DNP's buffer zones create friction with conservation interventions.

Government Initiatives

• Project GIB (2015–present): Centrally Sponsored Scheme for captive breeding and habitat management, administered through WII.
• Desert National Park (DNP): India's largest wildlife sanctuary by area (3,162 sq km), and the primary wild habitat for the species.
• Integrated Development of Wildlife Habitats: Central scheme under MoEFCC that funds grassland conservation and recovery programmes.
• National Action Plan for the GIB (2012, updated 2021): Multi-stakeholder framework covering habitat management, power-line mitigation, anti-poaching, and community engagement.

Way Forward

The IUCN SSC Bustard Specialist Group recommends expanding the captive population to at least 200 individuals before scaling up releases to ensure genetic diversity. The Supreme Court Expert Committee has advocated for creating wildlife corridors connecting DNP with the Pokhran and Barmer GIB landscapes. The 2nd Administrative Reforms Commission's emphasis on inter-agency coordination is relevant here — the MoEFCC–Rajasthan Forest Department–renewable energy regulator nexus needs a statutory coordination mechanism. A National Grassland Conservation Mission, recommended by multiple scientific panels, would provide the broader habitat security without which individual species recoveries remain fragile.

FAQ

What is the Great Indian Bustard and why is it so endangered?

The Great Indian Bustard (Ardeotis nigriceps) is a large ground-dwelling bird native to the dry grasslands of India, listed as Critically Endangered by IUCN. Its population has fallen from ~1,000 birds in 1969 to ~130 today due to powerline collisions, grassland conversion to farmland and solar parks, and a naturally slow breeding rate (one egg per year).

What happened on October 4, 2026?

Two captive-bred male GIBs were soft-released into a 200 sq km predator-free grassland enclosure within Desert National Park, Jaisalmer, marking India's first rewilding of captive-bred GIBs after a decade of the programme.

Which court order governs GIB conservation?

The Supreme Court case M.K. Ranjitsinh & Ors. v. Union of India (WP(C) 838/2019) has issued a series of landmark orders since 2021 mandating undergrounding of powerlines in GIB habitat, restricting new renewable energy projects in priority areas, and directing conservation actions through a court-appointed Expert Committee.
