In September 2004, a group of students from the Wildlife Institute of India (wii), Dehradun, went to the Sariska Tiger Reserve of Rajasthan for training. Excited about their work, they painstakingly trekked through the hilly 866 square kilometres (sq km) reserve. They couldn't spot a single tiger. Alarmed, they informed A J T Johnsingh, dean, department of animal ecology and conservation biology, wii.
