Explanation:
For the first time in India, 4 states have conducted a synchronised elephant census in May 2017.
These 4 states are Odisha, West Bengal, Chattisgarh and Jharkhand.
These 4 states have a maximum number of human-elephant conflict prone regions in India.
These states will conduct the census based on an identical set of rules using the direct and indirect counting methods.
The direct counting method is based on sighting of elephants while the indirect method uses the elephant ‘dung decay’ formula, in which the analysis of dung is used to estimate the population.
The indirect method has already been used by Karnataka and Tamil Nadu.
Direct method can be used alone because it is not possible to cover entire area during the census.
As per the 2015 census, Odisha has 1,954 elephants while Jharkhand has 700, Chhattisgarh and West Bengal had approximately 275 and 130 elephants, respectively.
