‘Deficiency in method of tiger enumeration' by R Krishna Kumar

Renowned wildlife biologist and tiger expert Ullas Karanth expressed serious reservations about the methodology adopted in the national tiger population estimation exercise. The results were released in Delhi on Monday, as per which the number of tigers across the country had increased from 1411 in 2006, to 1706.

He called for an end to the government monopoly on tiger monitoring, and suggested that outside expertise and resources be harnessed so as to ensure greater reliability, transparency and credibility in monitoring the fate of the national animal.

Responding to the national tiger estimation figures, Dr. Karanth, Director, Centre for Wildlife Studies, said that it was difficult to justify claims that the decline of the tiger population had been reversed when the various threats faced by the animal had not diminished in the last four years. “The full process of how these tiger numbers are generated for individual tiger populations and landscapes has not been made public in a scientifically acceptable manner. Only one scientific paper, which explains only a part of this protocol, has been published in 2011, based on data from the last round of estimation in 2007,” said Dr. Karanth. In a release, he said the monitoring of tracks by forest guards was not a substitute for more reliable methods of monitoring — using camera traps or DNA sampling — as had already been proven earlier in cases where tigers had vanished despite guards having done similar patrol-based monitoring. “To me the most serious flaw in the present government effort is the basic futility of trying to generate all-India-level tiger counts once in four years, even while ignoring the critical task of intensively monitoring key source populations year after year,” said Dr. Karanth.
