Discuss the significance of ex-situ breeding programmes in the conservation of critically endangered species, with reference to the Great Indian Bustard.

Ex-situ conservation means breeding and maintaining a species outside its natural habitat to create an "assurance population". With the Great Indian Bustard (Ardeotis nigriceps) reduced to barely a few hundred birds and uplisted to Critically Endangered [3], such intervention has become the last line of defence for India's grassland fauna.

Why ex-situ breeding matters

• Insurance against extinction: a captive stock buffers the species when the wild population falls below a viable threshold, as with the GIB's fragmented Thar population [3].
• Genetic reservoir: managed pairing preserves genetic diversity and avoids inbreeding depression in small, isolated groups.
• Scientific capacity: egg collection, artificial incubation and assisted reproduction generate reproducible protocols transferable to other threatened birds like the Lesser Florican [2].
• Restocking the wild: the stated objective of the MoEFCC–Wildlife Institute of India–Rajasthan programme is to release captive-bred chicks to rebuild wild numbers [2].
• Flagship value: a charismatic species sustains funding, and grassland protection for it shelters the wider desert ecosystem.

The GIB experience

• Project Great Indian Bustard, launched by the Rajasthan Forest Department in 2013, anchors conservation of the state bird, Godawan [1].
• The Sam (Jaisalmer) facility, with technical support from the International Fund for Houbara Conservation, Abu Dhabi, has been followed by a larger centre at Ramdevra [2]; captive-bred chicks now hatch annually [5].
• In July 2026, three chicks entered a purpose-built ₹9.25-crore rewilding tunnel at Ramdevra — four months of CCTV-monitored, human-contact-free conditioning before release into Desert National Park [4].

Limitations

• Captive rearing risks human imprinting and loss of predator-avoidance skills — precisely what the rewilding tunnel seeks to correct [4].
• High cost and long gestation demand uninterrupted Centre–State funding.
• Releases fail unless in-situ threats — power-line collisions, grassland conversion — are simultaneously addressed [3].

Ex-situ breeding is therefore not a substitute for habitat protection but a bridge that buys time for it. The GIB model shows its promise when paired with rewilding science and secured release habitat. Sustaining it — with bird diverters, grassland restoration and community stewardship — would advance both the Wildlife (Protection) Act's mandate and SDG 15 on life on land.
