The estimated number of tigers in the wild has risen for the first time in a century.
The latest census by the World Wildlife Fund (WWF) and Global Tiger Forum has counted 3890 tigers - almost 700 more than in 2010.
In 1900, there were 100,000.
Heather Sohl from WWF said the latest figures showed that tigers and their habitats could be saved when governments, local communities and conservationists work together.
The tiger census was released before a meeting in Delhi this week of ministers from 13 countries whose aim is to double the global tiger population by 2022.
