Deforestation, encroachment of habitat and poaching have devastated tiger populations across Asia, but countries with the big cats are working to increase their numbers.
Data compiled by the WWF and the Global Tiger Forum show that the global population of wild tigers has risen to an estimated 3,890 from an all-time low of 3,200 in 2010.
“For the first time after decades of constant decline, tiger numbers are on the rise,” Marco Lambertini, director general of WWF International, said in a statement.
It is the first time the number of the endangered cats has gone up since 1900, when there were 100,000 tigers.
India is home to more than half of the worldʼs tiger population with some 2,226 tigers roaming its reserves across 18 states, according to the last count in 2014.
Russia, Bhutan and Nepal also saw higher tiger numbers in their latest surveys.
However, experts cautioned that the numbers may be partly down to improved data gathering, with the inclusion of new sample areas and upgraded survey techniques as well as enhanced protection efforts.
Bangladesh registered a severe decline from 440 tigers in 2010 to 106 in 2015, though conservationists say this may have been due to an over-estimation of the population six years ago.
There has been a rapid fall in Indonesia because of heavy forest destruction to meet a growing global demand for palm oil, pulp and paper.

“Due to the concerted efforts of the government and other stakeholders, more than 70 percent of the global wild tiger population is in India,” Prakash Javadekar, Indiaʼs Environment, Forest and Climate Change Minister said in a statement.
Conference delegates are expected to discuss some of the key conservation issues including a unified anti-poaching strategy, monitoring protocols, habitat and landscape management.
Hollywood actor Leonardo DiCaprio, whose eponymous charitable foundation was also involved in the 2010 tiger conservation plan, voiced his elation at the increased numbers.
“Proud of @World_Wildlife and #LDFʼs efforts that have helped increase tiger populations for the first time in 100 yrs,” the Oscar-winner and environmentalist tweeted.
