Camera trapping is a capture-recapture technique used to document the presence of warm-blooded wild animals. Infrared cameras are set up in the field and take photos whenever an animal passes in front of the camera. The cameras can identify individual tigers based on their unique stripe patterns. Camera traps are also effective for surveying small carnivores. Sites are selected after a reconnaissance survey to identify potential animal activity areas. Digital cameras with infrared and motion sensors are used and placed at heights of 30-40cm apart from each other. The cameras remain active for 10-20 days at each station to photograph animals and record the date and time.

1. Survey technique- CAMERA TRAPPING
Objective: To document the presence of warm-blooded wild animals
Principle: The technique is capture-recapture, infra-red cameras are set within the field. The
camera clicks whenever a warm blooded animal crosses the camera line. In case of a tiger, each
individual has distinctive stripe pattern using which the individual level identification can also be
possible, if we recapture the same individual. Camera traps are efficient for surveying small
carnivores also.
Site Selection
Reconnaissance survey in study location will help to identify the potential activity sites of
the animal.
Method
Camera trapping technique is the one of the best methods for species documentation.
Digital camera with infra-red sensors for heat and motion detection sensor (Model: Cuddeback
Attack C1) is generally used nowadays.
Based on the detection of indirect evidences of the animals total number of camera trap
stations can be fixed. The camera traps were set at a height of 30cm – 40cm above the ground
and at least 150m apart from each other. The cameras were set up in default mode. The camera
trap locations can be marked using a GPS. The cameras can be kept active for 24 hours a day and
remain working there for 10-20 days in each station, it can vary according to convenience. The
date and time of exposure are automatically recorded on the images, as and when the images are
taken.
Analysis: Computer programme MARK is sued for the analysis
