New Delhi: The first generation of the reintroduced cheetahs in India may have to be monitored for their entire life and “success will take a lot of time” as bringing an animal back from extinction in a country is not an easy process, says Cheetah Conservation Fund (CCF) founder Dr Laurie Marker.The cheetahs being brought from Africa are used to other predators such as leopards and lions. However, there can be losses due to the interaction between the species in India, the American zoologist and researcher told PTI in an interview.The CCF has closely assisted Indian authorities in re-introducing cheetahs in the country. Since 2009, Marker has been to India several times to conduct site assessments and draft plans.(PTI)
