If these warnings are disregarded, the blame for any injury inflicted rests entirely with the intruder”

Photographs or plaster casts made/analysed
Study of pug marks can provide the following information reliably if analyzed skillfully:
• Presence of different species in the area of study.
• Identification of individual animals.
• Sex ratio and age (young or adult) of large cats
Cameras with motion sensors installed in the forest to capture the tigers.
Cameras could be left in dense forests for several days
No certainty that the tiger would walk into a camera’s range.
New method adopted by Wildlife Institute of India in Tiger Census 2015.
Forest department staff collect evidences of tiger presence such as pugmarks, scat, scratches on trees or other such unmistakable signs of tiger presence.
The next stage involved camera trapping – based on ground surveys.
