Since a lot of the southern area of the district is dense forest, it had provided a good refuge to the notorious bandit Veerappan, responsible for the death of over a hundred policemen. He was shot dead in an encounter with the specially formed Special Task Force (STF) on 18 October 2004 in Dharmapuri district, Tamil Nadu. He had been on the run for over two decades.
The presence of illegal quarrying for black stone imposes a great threat to the forests in the region.
