Descriptif
The present study was conducted in 400 km2 area which is the notified National Park area of Sariska Tiger Reserve from July 2008 to June 2012 covering all the three seasons monsoon (July to October), winter (November to February) and summer (March to June) with the following objectives : a) to evaluate the prey availability for the reintroduced tigers, b) to assess the prey selection patterns of the reintroduced tigers, c) to study the movement and ranging patterns of the reintroduced tigers and d) to assess the habitat utilization patterns, resource selection and response of tiger to various anthropogenic pressure in the study area.

Prey species availability was estimated by line transect method under distance sampling technique. A total of 52 line transects were walked. In total nine potential prey species were recorded on line transects. These were four wild ungulate species (chital, sambar, nilgai and wild pig), one primate (common langur), one small mammal (hare), two livestock (cow and buffalo) and one bird (peafowl). On each sighting of the target species, group size, age and sex composition, radial distance and sighting angle were recorded.
