DNA sample analysis for wild elephant count

LAKHIMPUR KHERI: DNA sample analysis through elephant dung would be done to count the estimated number of pachyderms present along the Dudhwa Tiger Reserve (DTR).

“DNA analysis from dung is a non-invasive method that doesn’t require coming into contact with the wild elephant,” said Sanjay Kumar Pathak, field director, DTR.

“Dudhwa field staff has been engaged in collecting fresh samples of elephant dung to be sent to wildlife institute of India (WII) for DNA analysis and study,” he added.Generally, counting of wild elephants is carried out by sighting them and registering their data on the M-STrIPES app.

However, this time as elephant population count and tiger population count estimation are being carried out simultaneously, DTR authorities have decided to carry out population estimation through DNA analysis method also.

“Samples of 72 wild elephants in Kishanpur and its surrounding areas have been collected and sent to WII. The exercise is on in Dudhwa, Katarniaghat and the buffer zone areas,” Pathak said.“Gene sequencing through DNA study would not only help ascertaining the identity of an individual wild elephant and their accurate numbers, it would also help to study some more vital information about them,” he added. “DNA study would help to establish the family and ancestry of an individual wild tusker. It would also help study the food pattern, in-breeding, health and would further help in management and conservation of wild tuskers,” he added.

During the last estimation of wild elephants in DTR, 149 wild elephants had been reported in Dudhwa.This number excludes the 26 domestic elephants kept in Dudhwa for patrolling, mananimal conflict handling, tourism and other park activities in DTR.The whole of the Terai region including Dudhwa, Katarniaghat, Kishanpur, Pilibhit Tiger Reserve and the buffer zone besides adjoining forest areas of neighbouring Nepal provide an ideal corridor to wild elephants.
