Abstract
Based on individual tiger monitoring of all re-introduced tigers in Sariska Tiger Reserve for two years, from 2016 to 2018, tiger kill data was analysed for demonstrating prey preference by the tigers. The observation of maximum number of tiger kills of livestock (77%) followed by Sambar Rusa unicolor (13.6%), chital Axis axis (3.6%), blue bull Boselaphus tragocamelus (2.4%) and wild pig Sus scrofa (0.95%) demonstrates very high livestock to natural prey ratio (L/N=3.3) indicating abundance of livestock population inside the reserve. The substantial increase of prey preference for livestock from 19.4% in 2011 (Mondal et al. 2012) to 77% can be corroborated with high observed increasing trend (y= 23.5x-7.43) of the cases of ex gratia relief for cattle killing by tigers from 2011 to 2017. We viewed this as evidence of increasing livestock pressure inside the reserve.
