Sariska, which a few years ago was discovered to be the grave of the endangered tiger rather than its sanctuary, is now ready to adopt the big cat again, possibly within a month. The tiger would come from Ranthambhore reserve currently experiencing a boom in the population of the animal, chief wildlife warden of Rajasthan R N Mehrotra told UNI. "Initially we would put just one animal, and its companion would be introduced a few months later, and this was being done to see how the newcomer was finding its new habitat,' he said.
