India’s tiger count has gone up by more than 30 per cent in the past four years, according to a latest study on tiger population which was released on Tuesday. The study put the number at 2,226, up from 1,706 in 2010 when the last such tiger-counting exercise was undertaken. Experts involved in the exercise said the steep rise in the number was more than what they had expected. “We all knew that the tiger numbers have gone up. But none of us had expected this kind of number. We were expecting the number to be around 1,900,” said Yadvendradev Jhala of the Wildlife Institute of India, one of the lead authors of the study that is the third edition of a four-yearly exercise aimed at assessing the state of tigers and their habitats in India.
