Wildlife Institute of India released the
official ‘Great Indian Bustard’ population estimate for the first time since
2017-18
Wildlife Institute of India (WII) released the first
official Great Indian Bustard (GIB) population assessment since 2017-18 and
reviewed the progress of Project Great Indian Bustard at the 91st Standing
Committee meeting of the National Board for Wildlife.
Key Findings
¨
Population Status:
Estimated 130 (±21) GIBs remain in the wild.
¨
Population has remained
broadly stable since the previous estimate of 128 (±19) during 2017-18.
¨
Trend analysis showed
stable detections, encounter rate, abundance, and occupancy since 2017.
¨
Habitat Status: GIB
occupies only about 16% of the surveyed landscape, despite the availability of
larger suitable habitat.
¨
Most birds are confined
to relatively undisturbed grasslands around the Desert National Park and
Pokhran Field Firing Range.
¨
The species prefers flat
to slightly undulating grasslands with sparse fallows and generally avoids
agriculture and infrastructure.
¨
Major Threats: Habitat
fragmentation due to expanding power transmission lines, agricultural fencing,
roads, water sources, and solar plants.
¨
Increasing mortality from
collisions with overhead power lines, as GIB has poor frontal vision and
limited ability to avoid wires.
¨
Other threats include
habitat loss, poaching, and egg predation.
¨
The report stressed that
long-term survival requires stronger habitat protection, threat mitigation,
habitat restoration, and conservation breeding.
¨
Other Observations:
During the survey, 35 GIB flocks, 1,568 Chinkara herds, and 79 Desert foxes
were recorded.
¨
Non-native species such
as Nilgai, pigs, and free-ranging dogs were also observed.
¨
The Thar Desert remains
the last viable landscape for large-scale recovery because of its extensive
contiguous natural habitat.
