Tiger population rises
The census, which was the most comprehensive and scientifically conducted exercise so far, used cameras installed at strategic points like water bodies in forests, as also in respective territories of big cats.
Computers were used to analyse and collate the data.
The 2006 Census had shown a sharp fall in the number of tigers in ?protected areas? – reserves, national parks and wildlife sanctuaries – in 19 states across the country.
According to it, India had only 1,411 wild cats left in its forests.
