The fourth cycle of the All India Tiger Estimation 2018, has entered the Guinness World Record for being the world’s largest camera trap wildlife survey. The citation at the Guinness World Record website reads- “The fourth iteration of the survey – conducted in 2018-19 – was the most comprehensive to date, in terms of both resource and data amassed. Camera traps (outdoor photographic devices fitted with motion sensors that start recording when an animal passes by) were placed in 26,838 locations across 141 different sites and surveyed an effective area of 121,337 square kilometres (46,848 square miles). In total, the camera traps captured 34,858,623 photographs of wildlife (76,651 of which were tigers and 51,777 were leopards; the remainder were other native fauna). From these photographs, 2,461 individual tigers (excluding cubs) were identified using stripe-pattern-recognition software.
Terming this achievement, a great moment, Union Environment Minister Prakash Javadekar in a tweet message said that India has fulfilled its resolve to double the tiger numbers four years before the target. The country now has an estimated 2967 tigers as per the latest census. With this number, India is home to nearly 75% of the global tiger population and has already fulfilled its resolve of doubling tiger numbers, made at St. Petersburg in 2010, much before the target year of 2022.
As well as unprecedented camera trap usage, the 2018 “Status of Tigers in India” assessment also conducted extensive foot surveys that covered 522,996 km (324,975 mi) of trails and sampled 317,958 habitat plots for vegetation and prey dung. It’s estimated that the total area of forest studied was 381,200 km2 (147,181 sq mi) and cumulatively the collection and review of data equated to some 620,795 labour-days.”
The All India Tiger Estimation done quadrennially is steered by the National Tiger Conservation Authority with technical backstopping from the Wildlife Institute of India and implemented by State Forest Departments and partners. The latest results of 2018 had shown that India now has an estimated 2967 tigers out of which 2461 individual tigers have been photo captured, a whopping 83 % of the tiger population, highlighting the comprehensive nature of the survey.
There is hardly any parallel of such a focused species-oriented program like Project Tiger across the world, which started with 9 Tiger Reserves, with 50 tiger reserves currently. India has now firmly established a leadership role in tiger conservation, with its bench marking practices being looked at as a gold standard across the world.
