After failing to reunite the abandoned tiger cubs with the mother, the Andhra Pradesh Forest Department is almost on the verge of giving up efforts to prefer in-situ conservation, an official said. Forest officials attempted reunification of the all-female litter of four cubs, found more than four days ago at Gummadapuram village of Nandyala district, for about three hours in the early hours of Thursday. "I don't think so (reunification), too much time has lapsed. Based on the decision (of higher-ups), we will probably shift them to a zoo for in-situ (within the forest) conservation," said Allen Teron, deputy director, Atmakur, Wildlife Division, Nagarjunsagar Srisailam Tiger Reserve (NSTR).
