If NTCA permits us to shift the cubs, we will initiate steps,” he said.The tigress has been missing since 20 days from the Antarasanthe division, Bisalawadi Range, in Nagarahole National Park.Tiger population** Bandipura National Park :110-112** Nagarahole National Park : 60-80** Biligirirangana Betta Tiger Reserve forest : 60 tigers.
