Ecological Status and Conservation of Tigers in India
To address the pressing need for tiger recovery, at a time when ecological information on tigers and its prey species were sparse, WCS – India developed suitable methods to gather baseline data.
During the course of the project, two animal population sampling approaches were adopted to estimate the abundance of tiger and its prey species in nine ecologically representative nature reserves in India. From the year 1995 to 2000, tigers were photographed in nine sites using self-activated camera traps, and the capture-history was analyzed by capture-recapture sampling methods. This project proves using relatively more sophisticated and robust capture-recapture models work more effectively than camera-trapping methods. Based on the project and the study, many management recommendations concerning the monitoring of tiger populations in India were made.
