"According to a census conducted recently in seven forest ranges in the STR, the tiger population has increased to 60, as against 50 during the previous census," Director of the reserve, Rajkumar told reporters here.
He said only one tiger on an average died every year -- due to illness, while crossing the water courses with its cubs, or during a fight with other tigers.
He said no poaching of tigers has taken place in the reserve and no feline has attacked a human so far inside the forest area.
