    Evaluating methods to monitor tiger abundance and its prey in Indian Sunderbans
    (wildlife Institute of India, Dehradun, 2019) Roy, Manjari; Sankar, K.; Qureshi, Qamar
    This study conducted to test and evaluate different methods for estimating tiger and its prey population in Sundarban that can be adopted as part of a monitoring programme. For this study techniques were applied for the standard spatially explicit capture-recapture, tailored according to the local conditions to estimate tiger density in Sundarban for three years. Tiger densities were estimated at 4.08 (SE 1.51) in 2010, 5.81 (SE 1.24) in 2012 and 3.15 (SE 0.88) tigers/100 km2 in 2014. The tiger abundance for my camera trapped study area generated through conventional mark-recapture was 11 (SE 2), 24 (SE 3) and 16 (SE 3) tigers for 2010, 2012, 2014 respectively. Ungulates occupy a primary position in the diet of tigers and a monitoring protocol for tiger should inherently include a component of prey base estimation. Boat transect based distance sampling to generate density estimates for four years.
