A government survey of wild tigers in Nepal has found their number has increased by 63% since 2009.
The survey was carried out between February - June, to assess the Bengal tiger population across a 600-mile stretch in Nepal and India. It found numbers had increased in all of Nepal's national parks.
The survey covered tigers in the Terai Arc, which spreads across the north Indian states of Bihar, Uttar Pradesh and Uttarakhand and into southern Nepal.
The BBC reports Nepal's survey concentrated on five protected areas and three wildlife corridors.
The number of tigers there have increased to 198, a rise from 121 in 2009. In particular, the tiger population in the south-western Bardia national park has risen from about 18 in 2009 to 50 this year.
The BBC reports officials have also increased anti-poaching efforts in Nepal.
There are thought to be fewer than 2,000 tigers left worldwide, with 60% of them in India.
