India’s wild tiger population has increased by more than 30 per cent in just four years, according to a new census released Monday, raising hopes for the survival of the endangered species.

The census found 2,967 tigers in the wild across the country, up from 2,226 four years ago in what Prime Minister Narendra Modi hailed as a “historic achievement”

“We reaffirm our commitment towards protecting the tiger,” Modi said in Delhi as he released the All India Tiger Estimation Report 2018.

“Some 15 years ago, there was serious concern about the decline in the population of tigers. It was a big challenge for us but with determination, we have achieved our goals.”

The massive surveys are conducted every four years, with the latest census using 26,000 camera traps that took almost 350,000 images across known tiger habitats, Environment Minister Prakash Javadekar said at the census release.

Images that showed the big cats were analysed using computer programmes to individually identify each creature. Wildlife and forestry officials also scoured 380,000 square kilometres of terrain.

In 1900, more than 100,000 tigers were estimated to roam the planet. But that fell to a record low of 3,200 globally in 2010.

That year, India and 12 other countries with tiger populations signed an agreement to double their big cat numbers by 2022.

Population numbers in the nation have risen steadily since falling to its lowest-recorded figure of 1,411 in 2006.

But they are yet to return to the figures recorded in 2002 when some 3,700 tigers were estimated to be alive in the country.

It is believed some 40,000 tigers lived in India at the time of independence from Britain in 1947.

Since then, the indiscriminate killing of the animal for its organs has led to a sharp decline, bringing them to the edge of extinction.

India’s growing population has also increasingly eaten into the territory of wild animals, pushing them into conflict with humans.

New Delhi has sought to improve its management of the predator, reserving 50 habitats — from Himalayan foothills in the northeast to regions in west and central India — exclusively for the animals.
