Pench national Park is famous as home to 'Mowgli'-- the protagonist of Rudyard Kipling's 'The Jungle Book'.
In a letter to the State's Chief Wildlife Warden, the CZA said that no safari shall be established without its prior approval.
"As per records of the CZA, no approval has been granted for creation of safari at Pench tiger reserve or Bandhavgarh tiger reserve. Therefore, no construction work should be carried out," the communique said.
The move assumes significance as many wildlife activists have been objecting to the creation of tiger safari in Pench and in Bandhavgarh national parks claiming it harmful for the big cats.
