The Guinness Book of World Records has all sort of records, some really weird, some totally silly and some truly awe-inspiring. One such record of sorts was made by the survey on tigers conducted in India in 2018-19. This survey, Status of Tigers in India 2018-19 has been recognised by the Guinness Book of World Records as one of the largest of its kind anywhere in the world. 

Conducted every four years, this is the largest camera trap wildlife survey conducted on earth. This is measured in terms of resources deployed, area covered and data gathered. It was conducted on behalf of the Government of India by the National Tiger Conservation Authority and Wildlife Institute of India. 

The survey concluded that India’s tiger population had increased by a third from 2,226 in the last survey done in 2014 to 2,927 (including tiger cubs) in 2018.

Here’s some mind boggling numbers:
