Flaws in a method commonly used in censuses of tigers and other rare wildlife put the accuracy of such surveys in doubt, a new study suggests. The study exposes, for the first time, inherent shortcomings in the 'index-calibration' method that means it can produce inaccurate results. Amongst recent studies thought to be based on this method is India's national tiger survey (January 2015) which claimed a surprising but welcome 30 percent rise in tiger numbers in just four years.
