Sampling comments: "Camera-trapping was carried out from 5th November 2015 to 8th June 2016... The entire study area was divided into 4 km 4 km grid cells to ensure even camera coverage... In each grid, two to three stations (with one camera trap per station) were placed along trails with animal signs. A total of 62 camera stations (LTL ACORN-5210 & 6210) were set up across the 400 km2 area. Cameras were placed with a minimum spacing of one km in order to increase independence of detection, with exceptions of 11 cameras... The infrared sensor was set to 50 cm above ground... To avoid pseudo replication, we considered consecutive images as independent images when the same species was photographed more than once during a period of less than 30 minutes... 57 camera traps were collected with a total sampling effort of 10171 camera workdays, 5 camera traps were lost or destroyed"
