In 2010, 13 tiger range countries set a target of doubling the population of tigers by 2022 – the day is celebrated as Global Tiger Day. Years of effort have brought fruits. The recent IUCN (International Union for Conservation of Nature) estimates the tigers' numbers have increased by 40 per cent – from 3,200 in 2015 to 4,500 this year. The recipe for it has been simple – government and community support, safe habitat, strict action on poaching, ensuring health and safety.
