Govt credits conservation with increase of wild tigers

India's latest tiger census shows a sharp increase in the number of the endangered cats in the wild, raising hopes that conservation efforts are working, officials said on Tuesday.

The census conducted in 2014 found at least 2,226 tigers in forests across the country, up from 1,706 counted in 2010.

Environment Minister Prakash Javadekar described the figure as a huge success story and said it was the result of sustained conservation efforts.
