Sampling comments: "Our camera trapping study targeted each year 20 rub trees... to ensure a representative coverage of the core area of the population (600 km2; Groff et al., 2015), we divided the area into four quadrants and selected five rub trees in each, ensuring that the distance between adjacent trees was greater than 3 km. This selection resulted in targeted rub trees (density of 0.05/km2)... Camera traps were set to function continuously... from April to November... We used UV565HD digital camera traps equipped with an infra- red LED flash for video recording... set to work... in continuous across the 24 hours"; there were "9302 camera days over the three years" and it is assumed that 1/3 pertain to 2012
