MATERIALS AND METHODS
❑ Between 2017 & 2019, we carried out annual surveys using camera
traps in 32 stations in comparable densities & various spatial coverages.
❑ In 2020, we established a monitoring site consisting of 52 stations, with a density of one station per 2 by 2 km grid cells.
❑ A pair of camera traps were installed in each station.
