This was disclosed by Minister for Environment and Forests Tariqul Islam in the Jatiya Sangsad yesterday. "Research is already going on under the project -- A study on behaviour and ecology of Tigers -- in the Sundarban Reserve Forests," he said in reply to a question from Begum Hosneara Gias (Daisy).

Besides, Tariqul said, the forest department is keen to see that no impediment is created in the way of natural growth in the number of tigers in the Sunderbans.

Arrangements have also been made to conserve the wildlife including tigers by digging canals (Khorma-Bhola-Aroarbar) to reach sweet water inside the Sundarbans, he said.

The Environment and Forests Minister further said that the people living on the fringes of the world's largest mangrove forests are being motivated to help the tigers go back to the jungle while they are seen in the human habitation.

Measures are also there not even kill any tiger if the animal is seen outside the Sundarbans, he told the House.
