A scientific paper, which appeared in conservation journal Oryx in 2007, points out that an earlier attempt to translocate lions in India failed because it wasn’t “monitored” enough. “An attempt to establish such a population in Chandraprabha Sanctuary, Uttar Pradesh, in 1957 failed because of a lack of monitoring and the small size of the Sanctuary (96 sq km) and because lions moved outside the sanctuary, leading to conflicts with people and poisoning and poaching of the lions,” said the paper.
