3,682 Tigers, and Three Reserves With None: India Rewrites the Map
Eighteen years after Sariska's reintroduction, a new roadmap targets 25 priority reserves — because a dozen of India's 58 hold fewer than three tigers each
What happened
The tiger number is the most quoted conservation statistic in India and the least informative one. A national total tells you nothing about whether the population is one connected whole or a set of crowded islands surrounded by empty ones — and the roadmap exists precisely because it is the latter. Learn the source–sink and metapopulation framework here, because it converts a headline count into an argument about connectivity, which is what the exam actually rewards.
Growth at the Top, Emptiness at the Bottom
India's Tiger Population
| Total reserves | 58 · ~85,000 sq km |
| 10–12 reserves hold | ~36% of all tigers |
| Reserves with <3 tigers | 12 |
| Reserves with zero tigers | 3 — Kawal, Kamlang, Dampa |
Corbett · Bandipur · Kaziranga — produce surplus animals
Sariska · Panna · Satkosia · Mukundara Hills

Project Tiger was launched in 1973 with nine reserves; India now has 58 tiger reserves covering roughly 85,000 sq km.
●The National Tiger Conservation Authority (NTCA) was given statutory status by the Wild Life (Protection) Amendment Act, 2006, and conducts the All-India Tiger Estimation every four years jointly with the Wildlife Institute of India (WII). The population rose from 1,411 in 2006 to 3,682 in 2022, growing at about 6 per cent annually.
●Distribution, however, is highly skewed: 10–12 reserves hold about 36 per cent of all tigers; 12 reserves have fewer than three tigers each; and three — Kawal (Telangana), Kamlang (Arunachal Pradesh) and Dampa (Mizoram) — have none, with Dampa recording zero in both the 2018 and 2022 estimations.
●Sariska (Rajasthan) is the landmark case: after local extinction, tigers were reintroduced from 2008 — the world's first successful scientific reintroduction into a landscape where the species had been extirpated — followed by Panna, and later Satkosia and Mukundara Hills.
●Reserves are conventionally classified as source populations (Corbett, Bandipur, Kaziranga) that produce surplus animals, and sink populations that cannot sustain themselves without immigration.
●The new roadmap identifies 25 priority reserves for habitat recovery, prey restoration, security enhancement and targeted reintroduction.
A national total of 3,682 conceals the operative fact: a dozen reserves have fewer than three tigers, and three have zero. Conservation now is a distribution problem, not a numbers problem.
◎ In Simple Words
India has far more tigers than it did twenty years ago — about 3,682, up from 1,411 in 2006. But they are not spread evenly. A handful of reserves are packed with tigers, while a dozen have almost none and three have zero. That is a problem, because tigers crowded into a few places compete with each other and eventually spill into villages, while empty forests stay empty. The government has now picked 25 reserves to fix — restoring prey animals, improving habitat and, where needed, moving tigers in, as was done successfully at Sariska eighteen years ago.

Frequently Asked
· People also askHow many tigers does India have, and how is the roadmap responding?
India's tiger population rose from 1,411 in 2006 to 3,682 in 2022, growing at about 6 per cent a year across 58 reserves covering roughly 85,000 sq km. The new roadmap identifies 25 priority reserves for habitat recovery, prey restoration, security enhancement and targeted reintroduction.
Prelims · GS3It was released to mark eighteen years since tigers were reintroduced into Sariska Tiger Reserve in Rajasthan.

Why is the distribution of tigers a problem?
Because growth has concentrated. Between 10 and 12 reserves hold about 36 per cent of all tigers, 12 reserves hold fewer than three each, and three — Kawal, Kamlang and Dampa — hold none. Dampa recorded zero in both the 2018 and 2022 estimations.
GS3 · EnvironmentSaturated reserves push dispersing sub-adults into human-dominated landscapes, raising conflict and mortality, while empty reserves deliver no conservation return despite absorbing management expenditure.
SOURCE All-India Tiger Estimation
What makes Sariska significant?
Tigers were reintroduced there from 2008 after local extinction, in what is described as the world's first successful scientific reintroduction of tigers into a landscape where the species had been extirpated. Panna, Satkosia and Mukundara Hills followed as reintroduction sites.
GS3 · EnvironmentIt is also the cautionary precedent: the original loss occurred because monitoring failed to detect decline until the animals were gone, and the reintroduced population has needed continued intensive management ever since.

What are source and sink populations?
A source population produces more individuals than it loses, generating surplus animals that disperse outward — Corbett, Bandipur and Kaziranga function this way. A sink population cannot sustain itself and persists only through immigration. The distinction underpins reintroduction strategy.
GS3 · EnvironmentThe long-term objective is a metapopulation — reserves connected by functional corridors so that genetic exchange continues, since small isolated populations lose diversity regardless of how well they are guarded.
SOURCE Wildlife Institute of India
Why can't tigers simply be moved into the empty reserves?
Because tiger density depends primarily on prey density. A reserve without ungulates cannot hold tigers regardless of habitat or protection, so reintroducing animals into a site whose prey base and protection have not been restored simply relocates the mortality.
GS3 · EnvironmentThis is why the roadmap sequences habitat recovery, prey restoration and security enhancement before translocation, and why the causes of emptiness at Kawal, Kamlang and Dampa must be diagnosed separately.
SOURCE NTCA roadmap
Which institutions manage tiger conservation in India?
Project Tiger, launched in 1973 with nine reserves, is implemented through the National Tiger Conservation Authority, which was given statutory status by the Wild Life (Protection) Amendment Act, 2006. The NTCA conducts the All-India Tiger Estimation every four years jointly with the Wildlife Institute of India.
Prelims · GS2The architecture is well developed, which is why India can identify its own failures this precisely. The weakness lies below it — reserve-level staffing, vacancies and field infrastructure vary enormously.
