THE CONTEXT: The Mahanadi Wildlife Division in Odisha announced on June 10 a cash reward of Rs 1,000 for rescuing gharials, a critically endangered crocodile species, and informing wildlife personnel. The division will also provide compensation to fishermen, whose fishing nets are destroyed by gharials.
Analysis:
- The announcement of the cash award is an effort to conserve the gharials in the Mahanadi river basin.
- The population of gharials in the area was on a decline over the last few years and had reduced to just eight in January 2021.
- It spiked to 36 when 28 gharials were born last month in the Satkosia gorge of Mahanadi at Tikarpada, Angul district.
- The breeding of these reptiles in their natural conditions occurred after years.
- The forest department has launched an awareness drive to save the crocodiles in over 300 villages spreading over five districts: Boudh, Angul, Cuttack, Sonepur and Nayagarh.
