Sampling comments: sampling was in May and June
"We used 2 digital camera trap models: Wildview Xtreme 2.0 and Wildview Xtreme 5.0... Cameras were placed on trails identified as wildlife passing points, oriented in a north–south direction. We fixed them to trees at a height ranging from 50 to 100 cm... we placed a bait consisting of oats, corn, sardines, and vanilla essence at a distance between 3 and 5 m from each camera... As an independent event for a given species, we considered a single record of that species at a site, within a 24-h period... each individual was considered as an independent record during the 24-h period"
