BHUBANESWAR: The annual tiger enumeration is set to commence in March and this time around, camera trap technique will not be the only method to be used to count the big cats. The last enumeration at Similipal where camera trap methodology was used and yielded in a low count had led to a huge uproar. Orissa lodged a protest with National Tiger Conservation Authority (NTCA) and some other states too joined in. This seems to promote NTCA and Wildlife Institute of India (WII) to adopt a more comprehensive methodology. In fact, state heads of wildlife wings met at Corbett National Park last week and discussed the matter threadbare. According to Chief Wildlife Warden PN Padhi, camera trap will be part of the enumeration methodology but not the only one. While GPS techniques would also be used to get a clearer view of the entire exercise, conventional methods of pug mark will be assessed too.
