The camera installation process has been completed in the first phase in the Sundarbans, one of the largest mangrove forests in the world.
The movement of the big cats will also be monitored for a month.

Technique
New technology replaced Pugmark method
-
Tiger estimation in the mangrove forest had traditionally been done by the pugmark method, the forest official said.
The last counting exercise was primarily based on camera trapping technique, he added.
The pugmark method was field-friendly, but due to some drawbacks, the Project Tiger authorities developed a new methodology for monitoring of tigers, co-predators, prey and habitat.

The camera trapping technique is more reliable than the traditional method of counting pugmarks, another forest department official said.
According to the All India Tiger Estimation Report 2018, India has emerged as one of the biggest and safest habitats for tigers in the world.
The tiger population in India had grown from 1,411 in 2006 to 2,967 in 2019, the last four-yearly tiger census report said.
