Jaipur: The number of big cats in Rajasthan's Sariska Tiger Reserve has increased to 40 after five new cubs were spotted recently, Chief Minister Bhajan Lal Sharma said on Thursday.

"We welcome new guests to Sariska," Sharma said in a post on Twitter. He shared the video and camera trap of the cubs with their mother 'ST22'.

The Chief Minister said that there has been a big increase in the number of tigers in Sariska and their number has reached 40 with tigress 'ST 22' giving birth to four cubs.

Sharing the video of the cubs, he said that the fourth cub of tigress 'ST 12' has also been captured in the camera trap and added that three of her cubs were seen in March.

He told that after the rehabilitation of tigers in 2008, tigress 'ST 12' gave birth to a child for the first time.

"Our government is fully committed to the conservation of the tiger, a symbol of speed and power, and to maintaining a balanced ecosystem for them," he wrote in his post.

The Sariska Sanctuary is spread over 1,213.34 square kilometers in the Aravalli Hills, the world's oldest mountain range.

In 2005 there were no tigers left in Sariska. To revive the tiger population here, a tiger rehabilitation program was started in 2008 by bringing two tigers and a tigress from Ranthambore National Park in Sawai Madhopu district.

Apart from tigers, Sariska also has a large population of leopards and other wild animals.
