Table 12 - Estimated tiger densities from photo-trapping rates 2001-2 Year Tiger photos Trapping effort Photos/trap night Trap nights/photo Density (tigers/100 sq.km) 2001 14 214 0.0700 15 11.98 2002 22 251 0.0700 11 16.66 Ranging patterns Ranging patterns were investigated using camera-trap data for all individuals and radio tracking from a single, adult male captured in 2003 and tracked for six months before his collar slipped off. Both methods showed extensive use of the plantation concession and forest concession by almost all resident tigers, the exception being Tiga Jari who lived on the border with the forest but was never detected outside the plantation concession. Calculated ranges were similar for both methods for the other three, showing tigers were ranging over at least 14km 2 . However, these results are likely to be highly limited by camera placement (which was not designed to measure home range) and tracking ability in forest (where the signal was never picked up) and these are not considered to represent complete ranges (Figure 23, Table 13).
