In 2003, 16 tigers lived in the reserve. In 2004, it was reported that no tigers were sighted in the reserve, and that no indirect evidence of tiger presence was found such as pug marks, scratch marks on trees, scats. The Rajasthan Forest Department explained that "the tigers had temporarily migrated outside the reserve and would be back after monsoon season". Project Tiger staff backed this assumption. In January 2005, it was reported that there were no tigers left in Sariska.
