The number of wild tigers across the globe has increased for the first time in more than a century thanks to improved conservation efforts, wildlife groups said on Monday.
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 world's 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.
