In a first of its kind, Telangana State will have eco-friendly bridges over a canal cutting across the tiger corridor linking the Tadoba-Andhari Tiger Reserve (TATR) in the Chandrapur district of Maharashtra with the forests in Telangana's Kumram Bheem Asifabad district. The intervention requires the laying of fertile soil to grow grass and plants over the structure, so that fragmentation of the reserve forest is camouflaged.

The ‘eco-bridges’ will be constructed at key spots along the 72 km-long, and at some places over a kilometre wide, right flank canal of the Pranahita barrage in the Bejjur and Dahegaon mandals, according to Chief Engineer (Projects) K. Bhagwanth Rao.

One of the locations tentatively earmarked for the eco-bridge is a spot close to Sulgupalli in the Bejjur forest range. Here, the canal is over a kilometre wide and the need to facilitate the movement of wild animals is quite necessary.

The concept emerged after visits by experts from the Wildlife Board of India and the Wildlife Institute of India. They were concerned about the large-scale destruction of pristine forest along the corridor, which would result in cutting off tiger movement between TATR and Bejjur.

The Telangana Irrigation Department has given its consent for the construction of the eco-bridges. Recommendations on the size and locations of the bridges are awaited from the National Board of Wildlife, Mr. Rao said.

In recent years, big cats from the TATR have ambled into the mixed and bamboo forests of the Bejjur range via the Sirpur forests. The TATR and its buffer area, which are contiguous with the Sirpur forests, boast of a speedily multiplying tiger population, the cause of the frequent migration of tigers into Sirpur and Bejjur.
