Burning bright: on India’s tiger census

Mains Paper 3: Environment
Prelims level : India’s tiger census
Mains level : Environment impact assessment, Conservations
Context
- If India has increased its population of tigers to an estimated 2,967
individuals in 2018-19, putting behind fiascos such as the Sariska wipeout
15 years ago.
- It adds to its global standing as a conservation marvel: a populous
country that has preserved a lot of its natural heritage even amid
fast-paced economic growth.
Background
- Since the majority of the world’s wild tigers live in India, there is
global attention on the counting exercise and the gaps the assessment
exposes.
- The National Tiger Conservation Authority (NTCA) has asserted in its
report, ‘Status of Tigers in India 2018’, that 83% of the big cats censused
were individually photographed using camera traps, 87% were confirmed
through a camera trap-based capture-recapture technique, and other
estimation methods were used to establish the total number.
- Previous estimates for periods between 2006 and 2010 and then up to 2014
indicated a steady increase in tiger abundance.
Tussle regarding the numbers
- Such numbers, however, are the subject of debate among sections of the
scientific community, mainly on methodological grounds, since independent
studies of even well-protected reserves showed a lower increase.
- It is important to put all the latest data, which are no doubt
encouraging, through rigorous peer review.
- Conservation achievements — and some failures — can then be the subject
of scientific scrutiny and find a place in scientific literature to aid
efforts to save tigers.
About present time situation
- There are several aspects to the latest counting operation — a
staggering exercise spread over 3,81,400 sq km and 26,838 camera trap
locations — that are of international interest, because some tiger range
countries are beginning their own census of the cats.
- Moreover, even developed countries are trying to revive populations of
charismatic wild creatures such as wolves and bears through a more accurate
outcome measurement.
- For India’s tigers, not every landscape is welcoming, as the official
report makes clear.
Divergences in population
- The less accessible Western Ghats has witnessed a steady increase in
numbers from 2006, notably in Karnataka, and Central India has an abundance,
but there is a marked drop in Chhattisgarh and Odisha; in Buxa, Dampa and
Palamau, which are tiger reserves, no trace of the animal was found.
- It is imperative for the NTCA to analyse why some landscapes have lost
tigers, when the entire programme has been receiving high priority and
funding for years now at ₹10 lakh per family that is ready to move out of
critical habitat.
Conclusion
- Ultimately, saving tigers depends most on the health of source
populations of the species that are estimated to occupy a mere 10% of the
habitat.
- The conflict in opening up reserves to road-building has to end, and
identified movement corridors should be cleared of commercial pressures.
- Hunting of prey animals, such as deer and pig, needs to stop as they
form the base for growth of tiger and other carnivore populations.
- As some scientists caution, faulty numbers may hide the real story.
- They may only represent a ‘political population’ of a favoured animal,
not quite reflective of reality.
