Sampling comments: "Camera trapping was conducted during December 2015 - February 2016... we created a systematic sampling grid in the political boundary of TTSF with cell sizes of 1 km2 and generated sampling points at the center of each cell, resulting in 23 camera-sites... At each camera-site we deployed four digital remote camera traps" and totals for two or four cameras per site are also reported, but counts recorded here pertain to one camera per site
"We used a threshold of 60 minutes to temporally distinguish independence of unique photographic events of the same species... Camera deployment was passive in that no bait or lure was used at the camera-sites"
